Dr. Deb Muth 00:00:09 Hi there, how are you? Bob Miller 00:00:10 Excellent! Pedaling as fast as humanly possible, but doing okay. Dr. Deb Muth 00:00:14 Good, good. Well, I’m looking forward to our conversation today. This should be amazing. Bob Miller 00:00:20 Yeah, it should be a lot of fun. Dr. Deb Muth 00:00:22 Yeah, anything that’s off-limits for you in, our conversation? Bob Miller 00:00:28 No. Dr. Deb Muth 00:00:29 Okay, anything you want me to make sure we cover for you? Bob Miller 00:00:33 Well, I mean, is it okay if we put a little plug-in for our software? Dr. Deb Muth 00:00:35 Absolutely. Bob Miller 00:00:36 Yeah. Dr. Deb Muth 00:00:37 Absolutely. Bob Miller 00:00:36 Yeah. Dr. Deb Muth 00:00:37 Absolutely. Bob Miller 00:00:38 Hey, can we… can we do a screen share? Yes, we can. Yeah, because I want to show you some maps, and… Dr. Deb Muth 00:00:43 Okay. Things like that, yeah, so… Perfect. So just let me know when you want to do screen share. Bob Miller 00:00:48 Okay. Dr. Deb Muth 00:00:49 And yeah, feel free to plug your software wherever you want to. Bob Miller 00:00:53 Okay, well, good. Let me pull up a, a slide for that, and give me one second, I just want to shut the door to my office to get the noise down. Dr. Deb Muth 00:01:01 No worries. Bob Miller 00:01:16 And, how should I refer to you? Dr. Debb? Dr. Muth, what do you like? Dr. Deb Muth 00:01:18 Dr. Deb is great, or Deb, either way, I’m pretty informal, so… Bob Miller 00:01:22 Yeah, and… Bob is fine for me. Okay. Yeah. Yeah, there you go. Why people feel like they need this, son. Special name, it’s like, seriously. Dr. Deb Muth 00:01:33 Right? I agree. Bob Miller 00:01:35 When I work with my clients, it’s like, Dr. Millison, just, just bop, just, just bop. Dr. Deb Muth 00:01:41 Yep, that’s how I am, too. Just call me Deb, it’s good. Dr. Deb Muth 00:01:44 They feel a little awkward with that, you know? They’re not used to that, but… Bob Miller 00:01:48 Alright. And you’re a naturopath, medical doctor. Dr. Deb Muth 00:01:52 A nastropathic doctor and a nurse practitioner. Oh, nice. Yeah, so I got the best of both worlds, right? Bob Miller 00:01:58 Yeah, damn. Okay. Alright, so here we go… There we go. Alright, so I got that ready, and then I will do a, I will do a screen share. I think you’re gonna really, appreciate what we’ve come up with. We’ve come up with the concept of, Cellular CPR. Dr. Deb Muth 00:02:23 Oh, nice! Bob Miller 00:02:24 And that is, construct the cell membrane, Protect the cell membrane. And restore it if it’s damaged. Dr. Deb Muth 00:02:32 Love that. Bob Miller 00:02:34 I love that. Yeah, so that’s what we’re focusing on, and then how, You know, we want to get to the point that, you know, most people think of genetics, they think of, like, 23andMe or Ancestry. Dr. Deb Muth 00:02:44 Yeah. Bob Miller 00:02:45 And then you have the professional geneticists who are looking at, you know, odd things that could create a disease. We’re looking at functional genomics. Dr. Deb Muth 00:02:54 Which is so much better. Bob Miller 00:02:56 Yeah. Are you familiar with what we do here, or… Dr. Deb Muth 00:02:58 A little bit, a little bit. So, it’ll be new to me, too, so I’m excited. Bob Miller 00:03:03 And how much time do we have? Dr. Deb Muth 00:03:04 We have an hour, give or take a little bit on either side. Do you have a hard stop anywhere? Bob Miller 00:03:10 No, no, I put a, I moved my clients around, and I don’t have anybody till, 3.30, so we’re good. Okay. Dr. Deb Muth 00:03:16 Perfect. Alright. Bob Miller 00:03:18 It’s like we’re getting started early as well, so… Dr. Deb Muth 00:03:19 Yeah, we’re getting started a little bit early, so that’s good. Bob Miller 00:03:22 Yeah, I just got my office cleaned up, so… Dr. Deb Muth 00:03:23 Okay, good. All right, are you all set to get started? Bob Miller 00:03:28 I’m good to go, my friend. Dr. Deb Muth 00:03:29 I’m gonna just record a little intro and a little bit of a, hook for people, and then we’ll get started. I’ll ask you to kind of tell us a little bit about yourself, and then we’ll just take this conversation wherever it’s supposed to go. Bob Miller 00:03:39 Okay, you got it. Dr. Deb Muth 00:03:40 Alright, sounds good. So what if the reason you’re not healing isn’t your diet, your supplements, or your labs, but it’s actually your genes? Dr. Bob Miller is uncovering how genetic variants, when combined with modern toxins, explain why some of us stay sick no matter what we try. Today, we’re talking genetic pathways, detox blocks, and the new science every wellness warrior needs to know. Welcome back to Let’s Talk Wellness Now, the show where we uncover the root causes of chronic illness, exploring cutting-edge regenerative medicine, and empower you to heal from the inside out. I’m Dr. Deb, your medical detective, and today, our guest, Dr. Bob Miller, is a true pioneer in functional genomics. He’s a board-certified traditional naturopath and the founder of Neutrogenetic Research Institute. And he’s the leading groundbreaking research on how genetic variants influence chronic illness, inflammation, and detoxification. His work has been recognized on international stages, uncovering links between genetic expression and conditions like Lyme disease, mast cell activation, or MCAS, and mitochondrial dysfunction. I’m so excited to talk to Dr. Bob today. He is gonna reveal some things that even I don’t know about, so I’m excited to learn alongside of you guys. So… Dr. Bob, let’s get started. Tell us a little bit about yourself, and kind of how you got on this journey. Bob Miller 00:05:04 Well, that’s, that’s interesting. I was sort of like a mid-career coming to the natural health field, because in my early 30s, I found myself with a severe case of ulcerative colitis. Bob Miller 00:05:15 And I was in the hospital for 21 days. probably within hours of death, pleading to death. And they told me I’ve got one option, and that is cut out the colon and wear a bag. Didn’t sound like a lot of fun. Dr. Deb Muth 00:05:27 Not an option I would want. Bob Miller 00:05:29 So, you know, the medical folks wasn’t real happy with me, but I said, yeah, I’d like to explore some alternative things.Never thinking that I’d get into this field, and then I just, you know, worked with some herbalists and things that I found absolutely fascinating. So, that’s how I got into this around 30 years ago. And, haven’t looked back since, and just having a… having a blast as we now move into how our genetics impacts things. So, that’s what we’re gonna… that’s what we’re gonna talk about today. Dr. Deb Muth 00:05:58 I’m excited to talk about this genetic thing. When you started over 30 years ago, what kind of patience and problems first inspired you to dig deeper into that root cause healing and kind of get into the genetic piece of it? Bob Miller 00:06:10 Sure. Well, you know, as a… now, I’m in a part of the country called Lancaster County, Pennsylvania, where there’s a lot of Amish and Mennonite, and they gravitate towards these things.So, this is their first thing to do, and that doesn’t work, then they’ll go other routes. So, you know, back then, we just saw typical, you know, a little tired, constipation. You know, a little bit of fatigue, arthritis, those kind of things. But things have changed dramatically over the years, as people are now getting more chronically sick. You know, it’s worse than it’s ever been. And what we’re finding is the, the culprits Primarily is mold exposure and Lyme disease. When people get those two together, they’re just… it’s an inflammatory cascade that nobody can seem to unravel. So that’s where we spend a lot of our time. And we’re also spending a lot of time looking at mental health, like ADD, ADHD. And, we give… this year I’ll be speaking at three autism conferences. And we can dig into that a little bit as to why we think we’re seeing such a dramatic increase. And aside from autism, that used to be 1 out of 1,000, now it’s 1 out of 33, or 23. You know, we’re also seeing dramatic increases in ADD, ADHD. People are stressed out. And today, I think we’ll have the time to actually go through and show how environmental factors combine with genetics to cause that to happen. So we’ll… we should have a fun visit here today. And today, I think we’ll have the time to actually go through and show how environmental factors combine with genetics to cause that to happen. So we’ll… we should have a fun visit here today. Dr. Deb Muth 00:07:37 This should be a fun visit. We can cover lots of topics. I am so excited. So, you founded Nutri Genetic Research Institute in 2015. What did you hope to accomplish, and what kind of surprised you in your findings so far about that? Bob Miller 00:07:51 Well, you know, let’s back up at what, you know, genetics is used for. Everybody’s familiar with 23andMe and Ancestry that, you know, tells you where your ancestors came from. Then you have your professional geneticists. I mean, these are people with a degree in genetics. And they’ll look for, you know, very odd sort of things that are prone to relate to a disease. So there are disease-related genetics. Well, in functional, we don’t look at either of those. We look at For example, how you’re breaking down your fats and utilizing them. How you’re recycling your glutathione. How you might be handling your iron. And none of those are disease-causing on their own.And none of those are disease-causing on their own. But when they pile up on you, and then combine that with environmental factors, that’s when things start to go south on us. So, that’s what we’re doing, we’re looking at patterns. And our first foray into this was, we did studies on Lyme disease. And our first foray into this was, we did studies on Lyme disease. So, we looked at, like, I think 50 people with Lyme disease. We looked at their genome. So, we looked at, like, I think 50 people with Lyme disease. We looked at their genome. And we found patterns that were more evident in those with Lyme. Now, this doesn’t… these genetics don’t mean you get Lyme, it just means if you get Lyme, you react worse to it. And we found patterns that were more evident in those with Lyme. Now, this doesn’t… these genetics don’t mean you get Lyme, it just means if you get Lyme, you react worse to it. So, as you know, some people get Lyme, they go on a round of antibiotics, and they’re done. So, as you know, some people get Lyme, they go on a round of antibiotics, and they’re done. Others have a little more struggle, and then others are struggling terribly for years. So there’s an old adage of genetics loads the gun, environment pulls the trigger. Dr. Deb Muth 00:09:14 Yeah, that is so true, and I think when we’re talking about Lyme and mold and things like that, we forget sometimes that our genetics can predispose us to be more sensitive to those things, and if we have genetic pathways where we don’t clear things properly, it’s harder for us to get them out of the body. And then you add on that whole rain barrel effect that we’ve always used as a functional medicine term, right? If the barrel’s half full, you’re okay. If it’s full, and now it’s spilling over, it’s a bigger problem. Have you guys found, too, that some of these environmental things actually are changing the genetics of people, or how they’re processing their own genetics? Bob Miller 00:09:53 Well, let’s go back to, Genetics 101. But we’ll go back a little bit further. So, what an interesting mechanism, what a miracle the body is. Bob Miller 00:10:03 Fats, carbohydrates, proteins, drink water, breathe air, expose the sunlight, and somehow everything gets made. I mean, when you just step back and think about that, it’s like, It’s pretty darn amazing. Dr. Deb Muth 00:10:15 I always tell women, you know, the fact that we get pregnant and we have healthy pregnancies and births is a miracle, because if we had to try to control that, that wouldn’t work so well. Bob Miller 00:10:25 Right. Well, that’s another miracle. These microscopic sperm and egg, human being, 9 months later, it’s like. But even inside of us. We are making our hair, our skin, our nails, our blood vessels, our ATP, our energy, it’s all being created. Well, that gets created by enzymes. So, enzymes take one substance, combine it with something else, and make something new. Then another enzyme comes along and does the same thing. Your DNA is the instructions on how to make the enzymes. So, when we are conceived. If it’s a, if it’s a female, of course, it’s the XX, the two chromosomes. You know, we’ve… everybody’s seen those… the genetics that… Listed pair. So, if it’s a female, the father donated the X enzyme. And the mother has no choice but to give the eggs, so that’s female. If the father donates the Y, you have a male that’s in chromosome number 1. Then 2 through 23 is the rest of the instructions on how to make enzymes. So, what can happen? We can get what are called SNPs, single nucleotide polymorphisms. And SNPs just mean that the instructions to make the enzyme’s not quite as good. So, if one parent gives a SNP on the making of an enzyme, The enzyme’s fine. It works. But, general rule of thumb, It may only work at 70-80% of efficiency. Now, a good analogy is think of an 8-cylinder and a 6-cylinder car. If parents give you good information, that’s like having an 8-cylinder car. If one parent gives you that snip, it’s like having a 6-cylinder car. Now, is a 6-cylinder car a fine car? Sure. It’ll get you from point A to point B, but it’s just going to have the power of an 8-cylinder. Then if both parents give you a SNP on the same enzyme, it may be 30-40%, and that’s like having a 4-cylinder car. Sits in the driveway, looks the same, puts gas in it, everything. But if you’ve got a 4-cylinder car. Probably not a good idea to go cross-country pulling a trailer behind you up and down mountains. Dr. Deb Muth 00:12:29 This is true. Bob Miller 00:12:32 So… We can get an 8-cylinder, 6-cylinder, or 4-cylinder enzyme. Now, if it’s not under a lot of stress, if that 4-cylinder car is just taking you to the bank and the grocery store. It’s just as good as an 8-cylinder car. But if you gotta pull that trailer, and there’s a lot of stress on it, being mountains, it’s gonna struggle. Now, there’s one other little caveat to this, and that is some genetic mutations are gain-of-function. They actually work faster. Now, we have enzymes that do all kinds of things. We have enzymes that make and recycle our antioxidants, but we also have enzymes that make inflammation. No, that’s a good thing, because if we get a virus or bacteria, if you didn’t make inflammation to kill it, well, we’d all die of infection. So, you know, we tend to think of free radicals as bad, antioxidants as good. They both play an important role. But interestingly, some of the major enzymes that make inflammation, they can be overactive. They can be turbocharged. And when they’re stimulated by environmental toxins, they overreact. Bob Miller 00:13:40 And therein lies the problem. When they overreact, we have a problem. Bob Miller 00:13:46 So, if we have genes that overreact when stimulated. And then the enzymes that take care of inflammation are underactive. Then you’re gonna be more inflamed. You know, the majority of people that, you know, come for functional medicine Or naturopathic help, or… Inflammation that they can’t seem to get under control. Dr. Deb Muth 00:14:06 Right. Bob Miller 00:14:07 And we will be, you know, during this hour, we’re going to look at some of the pathways that make that happen. So, what we can do then, we can’t change our genetics. When you’re conceived, that’s the hand you’re dealt. When your life would be over, if someone would take some tissue and measure, it’d be exactly the same as conception. Does it change. Bob Miller 00:14:28 The enzyme’s ability to do its job may be compromised. Because remember I said there’s a, the enzyme takes a cofactor. So an enzyme takes substance A, cofactor, make substance B. Well, if that cofactor’s not there, the enzyme’s not going to work either. So, you could have an 8-cylinder car, and if there’s no gas in it, it’s not going anywhere. So… It’s the strength of the enzyme, it’s the cofactor to do the A to B conversion. And that’s what we’re going to get into. So, many people say, well, where did these SNPs come from? Nobody knows for sure. Sometimes they’re what’s just called de novo, when the sperm and egg go together, the instructions get mixed up a little bit. We do believe a lot of it came from a long time ago, when we were almost wiped out by sexually transmitted diseases. And those STDs were altering the genes when the conception, in other words, when the sperm went into the egg, the STDs were interfering. And causing the problem, so… I often joke, if you want to blame somebody. Blame your great-great-great-great-great-great-great-grandparents for, being a bit promiscuous, so… Dr. Deb Muth 00:15:31 Yeah, for being… having a little too much fun, right? Bob Miller 00:15:35 So, we don’t know for sure, but, you know, there are some that, But most of the SNPs that we get inherit from our parents. So, if you look at a child. And you look at the SNPs. 99.9% of the time, it came from one of the parents. Dr. Deb Muth 00:15:50 In identical twins, do they have the exact same identical makeup? Bob Miller 00:15:54 Yep, Dr. Deb Muth 00:15:56 But not in fraternal twins, correct? Bob Miller 00:15:59 No, no, those could be different, Jeff. Dr. Deb Muth 00:16:00 It could be different because they have different sacs, they’re not sharing that same genetic makeup. Bob Miller 00:16:04 Yeah, so keep in mind, both your mother and your father have, you know, the two And so you get one from one parent, one from another. Dr. Deb Muth 00:16:13 So… Bob Miller 00:16:14 Interesting situation. I had, 3, 3 boys. And, we were looking at an enzyme related to breaking down oxalates. Now, the mother and father each had one SNP, and that’s called heterozygous. Three boys, and they all come together, they’re Amish boys, they’re a lot of fun. And I looked at their genomes, and the one boy didn’t have any SNPs at all. And one had won. And the other one had two. Dr. Deb Muth 00:16:41 Interesting. Bob Miller 00:16:42 So, we don’t quite know how these things get handed off, but with the parents each having one, you could have a child with none, one, or two. So, the one, his ability to break down oxalates, which is fine. The other one was slightly impaired, and the other one was dramatically impaired. So, you can have 3 children, and it all depends what the parents have. Now, if a parent has a homozygous, or 2 copies. And the other parent has nothing. Every child will have one. Okay. If both parents are homozygous, that they both have two, Every child will have two. Dr. Deb Muth 00:17:19 too. Bob Miller 00:17:20 Yes, so that’s the way it works, but, you know, but it’s somewhat rare that both parents are homozygous on an enzyme, but it can happen. Dr. Deb Muth 00:17:27 Do we think that infections today, like Lyme disease or mold exposure, things like that, if the parent, the woman, primarily, I’m thinking, is pregnant, and she actively has these infections. Can those infections affect the genetics, kind of like a past sexual transmission did where we thought back in the day? Bob Miller 00:17:47 Yeah, I… I mean, I’m not that much of a geneticist to answer that for sure, but my thought would be no, that at conception, the pattern’s made. Dr. Deb Muth 00:17:55 Okay. And then that’s… that’s the hand you’re dealt. Bob Miller 00:17:58 Yeah. So, I tell people we have good news and bad news. The good news is we can compensate for the weakness. The bad news is we can compensate for the weakness. Dr. Deb Muth 00:18:09 That is so very true. Bob Miller 00:18:11 Yeah, we can’t, because I often get asked, so we’ll do some things now, and we’ll check my genes again, and they’ll be better. It’s like, nope. Dr. Deb Muth 00:18:18 Oh, – – Bob Miller 00:18:19 You gotta play the hands you’re dealt, so… Dr. Deb Muth 00:18:21 That’s right. Bob Miller 00:18:22 You can test your genetics… if you’re looking at the same enzyme, you can test it every year. It’s not gonna change. It’s like the blueprint. Dr. Deb Muth 00:18:30 It’s good and bad, right? It’s the one test you only have to do once in your lifetime. Bob Miller 00:18:34 No, unless, you know, like, our. Dr. Deb Muth 00:18:36 All the time. Bob Miller 00:18:37 Yeah, now our test looks at, called the Functional Genomic Analysis Test of your genomic Resource. We look at 220,000 steps. Dr. Deb Muth 00:18:46 Wow, that’s a lot. Bob Miller 00:18:47 That’s not all of them. Dr. Deb Muth 00:18:49 Right. Bob Miller 00:18:50 So, maybe in the next year, we’re gonna come out with our third version of the chip. And then, if someone wants to get those new things that weren’t on it, they’d have to repeat. But whatever we measured is gonna stay the same. Dr. Deb Muth 00:19:03 That’s a lot of SNPs to look at. Bob Miller 00:19:05 Keeps us busy. Dr. Deb Muth 00:19:06 But there’s still, but there’s still SNPs that we. Bob Miller 00:19:09 That we’d like to have that we don’t have, so… Bob Miller 00:19:11 We started out with version 1 on our genetic test, then we worked with version 2, and we’re already compiling a list of what version 3 would look like. So if somebody has our version 2, And we’re saying, you know what, it’d be nice if we could see these, well, then you’d repeat, but it won’t change what you already know, so… Dr. Deb Muth 00:19:29 Got it, got it. So, when you started out, and you started looking at the research of Lyme disease and chronic infections, which detox pathways are most important for people who struggle with those conditions? Bob Miller 00:19:43 Okay. You know what might make sense as we do a screen share, and I’ll actually show you the pathway. Does that make sense? Bob Miller 00:19:48 Alright, so… let’s see if I… let me just press the share… Dr. Deb Muth 00:19:52 Yep, you should just be able to press share. Bob Miller 00:19:54 And… number 2. Okay. Are we seeing the screen there? Bob Miller 00:20:01 Okay. Dr. Deb Muth 00:20:02 So, this is a map that we made. Bob Miller 00:20:05 And by the way, this is not… All-inclusive of all the things we look at, but we believe this is a core issue. So, where we’re going to start here, there’s something called the microglia. And the microglia are glial cells. They’re in the brain and the central nervous system. And they’re very interesting little creatures, because most of the time, and this is just a drawing of what they sort of look like. Most of the time, they’re in what’s called the M2 anti-inflammatory mood. What that means, these little guys pick up dirt, debris, Recycle them. Turns on an enzyme called interleukin-10 that’s anti-inflammatory. And just kind of does general housekeeping. And just kind of does general housekeeping. However, when a trigger comes along. However, when a trigger comes along. They… it’s the same glial cell, but it moves over to a very pro-inflammatory enzyme. A pro-inflammatory glial cell. And it triggers these 3 enzymes, Actually, these four. That are pro-inflammatory. Tumor necrosis vector alpha, Interleukin-6. NF Kappa B, Inos. Now, these create inflammation. So you might think, well, why is that good? Well, if you have some foreign invader, virus, bacteria coming in, parasite. If you didn’t have these guys coming to the rescue, you would just die of infection. So, these guys are your friend unless they’re your worst enemy. Because TNFA, and we’ll show you when we actually do a demo account, TNFA can be overactive. So, in other words, it over-responds. Interleukin-6 can be overactive. And if Kappa-B can be overactive. The INOS, and I’ll explain each of these as we go through a demo, can be overactive. Now, what that means is, you’re very good at killing virus and bacteria. But this is where autoimmune disease comes in, and just inflammatory conditions. Now, this is just speculation, but we think what happened is, as you know. Thousands of years ago, we didn’t have refrigeration, we didn’t have sewer, we didn’t have pure water, and we didn’t have antibiotics. So, if you made it to 40, you were an old-timer, because everybody was dying of infection. So, what we believe happened is, by what’s called natural selection, Having these overactive. A thousand years ago was to your advantage. Dr. Deb Muth 00:22:31 Hmm. Bob Miller 00:22:32 But now… We have pure water, we have refrigeration, we have sewers, we have antibiotics. But now we have environmental factors that are stimulating them. Now it’s to our disadvantage. And we’ll talk about that a little bit as it relates to the hemochromatosis genes and maybe the G6PD. Dr. Deb Muth 00:22:48 Yep. Bob Miller 00:22:49 Now, why are we becoming so inflamed? Let’s look at the triggers. Now, one of my, favorite expressions is. I was born all the way back in 1954. Dr. Deb Muth 00:23:01 And it was a different world back then. Bob Miller 00:23:05 These are some of the triggers. And we’ll get into these, but right now, high fructose corn syrup, And the high-fat diet. High fructose corn syrup only came about in 1968. So now we’re being exposed to high fructose corn syrup. Then… we didn’t have these, these viruses like COVID. Dr. Deb Muth 00:23:26 Yeah. Bob Miller 00:23:27 Now, there’s now pretty strong evidence that COVID Was actually, you know, made as a gain of function. It’s debated, and I’m not taking an opinion on it, but there’s some people who believe Lyme disease was also a part of experimentation. Dr. Deb Muth 00:23:40 Go. Bob Miller 00:23:41 Then we have molds, and it appears as though mold is getting stronger. you know, 20 years ago, when I was seeing folks, mold wasn’t on the radar. I would say 7 out of the 10 folks we speak to today have mold problems. Yeah, 20 years ago, we talked more about mold allergy being an issue versus mold toxicity being an issue. Right. So… I know some folks are, you know, speculating what’s happening, but one of the theories out there is that EMF is strengthening mold. I don’t know if you ever heard that theory, and I don’t… Dr. Deb Muth 00:24:13 I have. Bob Miller 00:24:14 I’m not claiming it’s true, but it’s an interesting theory. Then even, you know, your black mold from water-damaged buildings. Then our air pollution is getting worse. We’re getting more toxic metals. Dr. Deb Muth 00:24:26 You know, if we have a… Bob Miller 00:24:27 You know, we’re gonna look back someday and say, what were we thinking, smearing aluminum into our armpits? The, what were we doing putting mercury in our teeth? Then, you know, glyphosate. When I was a kid, there was no glyphosate. So, all of these herbicides and pesticides. Polychlorinated biphenols, And then EMF. So, we love our cell phones, you know, and I think unless you, or in the middle of the desert, or down in a cave, you’re being exposed to EMF somewhere. So, you know, we have our cell phones with us, we have, We have Wi-Fi, the towers are everywhere. And we don’t know long-term, but we may find that this can… this creates some inflammation. And I don’t know if you get any folks, but do you have any folks that have… are they EMF sensitive? Dr. Deb Muth 00:25:16 Oh yeah, we have a whole bunch of them. Bob Miller 00:25:18 Yeah, and then if you have any TBIs, So, plenty of things here. that will stimulate into the microglia, M1. Now, you could say, well. We’re all pretty much exposed to the same thing. Why do some people get hit harder than others? So here’s where we’re gonna start. There’s an enzyme called Nrf2 and RF2. And Nrf2 is the enzyme that senses when there’s inflammation. And turns on hundreds of anti-inflammatory enzymes. We’ll show when we do the demo, you can have genetic weakness on NERF2. And NERF2 inhibits and slows down microglia M1. supports M2. Now, if it’s not complicated enough, there’s an enzyme called KEEP1. And KEEP1 inhibits NRF2. And you can actually have gain of function on keep 1, that makes Keap 1 stronger. So… A lot of the people who land on my doorstep So… A lot of the people who land on my doorstep Both parents gave a mutation on KEEP1, making it overactive. Both parents gave a mutation on KEEP1, making it overactive. Dr. Deb Muth 00:26:31 Hmm. Dr. Deb Muth 00:26:31 Hmm. Bob Miller 00:26:32 Suppressing Nrf2, nerve 2 might be weak. So, nobody’s putting the brakes on, M1. And by the same token, Nerve 2 supports M2. Then there’s a process called mTOR and autophagy. mTOR stands for mammalian tard of rapamycin, the growth of new cells. And then autophagy, taking our dead cells and recycling them. We need a balance between the two of them. If we didn’t have mTOR, the sperm and the egg would never become the baby, the baby would never become the adult, we wouldn’t make new cells. But our cells are constantly, you know, the old cells dying off. Autophagy is where we take that debris from the cell and recycle it, just like a farmer Plows the crop under at the end of the year. The dead plant then becomes the fuel for the spring, your dead cell becomes the fuel for the spring, and that’s autophagy. So we’re gonna look back someday and say, what were we thinking? We give our animals growth hormones so they get fatter faster. Oh my. So, we consume those animals, and inventory runs faster. Now, for anybody who’s, You know, maybe above 40, 45 years old. Think back when you were 12, and what did girls look like? They were primarily flat-chested little girls. Now they look like 16-year-olds. Because environmentally, we’re jacking up mTOR. So, mTOR stimulates microglia M1, suppresses microglia M2. Probably 80% of the folks we visit with. This is the part of the problem. NRF2 is weak. mTOR is strong. Environmental factors come along. And this guy gets carried away. He doesn’t do that burst and move back. Stays here. We’re calling that How environmental factors create a locked-in, pro-inflammatory. and neurotoxic phenotype. In other words, once it starts, it just keeps… Feeding upon itself. Alright, so what happens now when microglia is overactive. it triggers these 3 enzymes, TNFA, N of kappa B, And interleukin-6. Each one of these can have genetics that make them run stronger. Then it stimulates an enzyme called NLRP3, Which makes what are called inflammasomes. Now, guess what inflammasomes can be? Your best friend or your worst enemy? Because they will, if you’ve got, again, a virus or bacteria, or possibly even some bad cells in the body. They will zap them. Well, that’s good. Unless it’s overactive. Unless it’s overactive. And then what it does, through interleukin-1 beta, makes excess glutamate. And then what it does, through interleukin-1 beta, makes excess glutamate. Anxiety, gut inflammation, OCD, ADD, autism. And, you know, glutamate, we’ll talk about that a little bit, but glutamate makes you intelligent, highly motivated go-getter. but can also be excitatory. And then, look what it does. Let’s see, do I have the drawing tool here? Yes, I do. Okay. So, it comes down through here, Makes the glutamate. Comes back up through here. through the ADORA 2A enzyme, Then we’ve got a feedback loop that feeds upon itself. Then, through interleukin-18, we make histamine. and mast cells. And then through histamine receptor site number 1, we come back and spin it. And now you’ve just got this spinning feedback loop. So, the glutamate will make you anxious, the histamine will give you allergies and make you anxious. And you’re allergic to everything, and you’re feeling horrible. Now, it doesn’t end there, Dr. Dad. It then goes on to make something called gast dermins that creates pyroptosis, where it actually starts punching a hole in the cell membrane. And you’re only going to be as healthy as your cells are. Just a little background. You know, we’re made up of trillions of cells, and each one of them has what’s called a lipid bilayer, made from lipids, which comes from fats. And you’re only going to be as healthy as those membranes are. So that’s why we coined an interesting phrase. Cellular CPR. Construct the cell. Protect the cell. And restore the cell membrane. And we believe that’s going to be revolutionary in the functional medicine world. So… It’s not hard to figure out that if you start punching holes in the cell membrane, that’s not a good thing, okay? Bob Miller 00:31:22 Now… There’s an interesting molecule called NAD. Thicotide adenoside dinucleotide. And anybody who’s in the, you know, listening to the health podcasts and things, they’re… They’re, they’re learning about NAD. And I’m going to show you a chart later, all the good things that NAD does, but For the most part, it helps what’s called sirtuins. And sirtuins are quite interesting. If anybody’s looking at longevity. The sirtuins is where they’re looking at.Because sirtuins turn on good things. Turn off bad things. And I’ll show some charts on that later. So for right here, this sirtuin uses NAD, to slow down NF-kappa-B. CERT 2 uses NAD to slow down an ORP3. So, if we’ve got genetic weakness on these, or we don’t have enough NAD, We don’t hold this pathway back. Make sense? Dr. Deb Muth 00:32:24 Yeah, makes perfect sense. Bob Miller 00:32:25 Now, I’ll show this a little bit later. So, people are like, oh, well, I’m gonna start taking some NAD. Dr. Deb Muth 00:32:31 Right. Bob Miller 00:32:32 And there’s functional doctors who give NAD intravenous. It was just this morning, I was talking to a woman who said, Oh my gosh. I went and got intravenous NAD, and it took me a month to recover from that. Dr. Deb Muth 00:32:45 Hmm. Bob Miller 00:32:46 what happens is, and I’ll show this in a little more detail, there’s an enzyme called CD38, that’s stimulated by NF-kappa-B. And it takes NAD, To make intracellular calcium. that stimulates NLRP3 and actually makes things worse. So, if we have this guy upregulated, and I’ll show a chart what does that. taking NAD will make you worse. Again, when I go into the software, I’ll show you that whole pathway, so… I would encourage people, you know, just don’t go out and start taking massive amounts of NAD, you know, stick your toe in the water, see how you do. Because everything you’ve heard about, how good it is, is true, unless this guy says, oh, thank you very much, let me make more inflammation. Now, this might be part of our innate immune system, that if we have some pathogen that’s gonna kill us. By golly, we want that to happen. But if this is happening by environmental factors, Then it’s detrimental. So the immune system that protected us a thousand years ago now might be turning on us because of the environmental factors that we showed earlier. All right. Then there’s an enzyme called PARP that’s NAD-dependent, and that actually repairs strain breaks in your DNA. Now, the next thing that happens… is there’s an enzyme called NADPH oxidase that gets stimulated. and something called INOS. Now, I’m sure most people know about nitric oxide. It’s a gas that dilates your blood vessels. That’s why sometimes they’ll even give people drugs, nitroglycerin, to boost their nitric oxide. That’s why people are doing beetroots and other things to boost their nitric oxide. But there’s an OS3 enzyme that makes the nitric oxide that’s good for blood flow. But there’s an INOS That makes nitric oxide to kill pathogens. probably might be the third or fourth time I’ve said this. That’s a good thing, unless it isn’t. So, if it’s killing some pathogen, great. It was just misfiring. it combines… With superoxide that’s made by this enzyme, and makes something called peroxynitrite, which is one nasty free radical that chews you up and spits you out. So, the NOx enzyme, NADPH oxidase, uses NADPH, To make this free radical called superoxide. If we have time, we’ll get into it. NADPH is what your body needs to recycle your antioxidants.So, I coined the phrase, the NADPH steel. Where the NOX enzyme takes this very important NADPH, And rather than being useful, makes superoxide. Now, again, is that fine if you’ve got some bacteria to kill? Of course. But if it’s just chronically running, it’s just making all this chronic inflammation. Then it makes something called hydrogen peroxide. And we need to clear hydrogen peroxide by 3 enzymes, catalase, thyroid reduction. And glutathione peroxidase. If we have genetic issues on here, or we don’t have the cofactors. There’s something called the Fenton reaction, discovered in 1895 by Dr. Fenton. Where hydrogen peroxide combines with iron to make what are called hydroxyl radicals. And guess what they do? They create lipid peroxides, That damages your cell membranes. Now, again, the body’s pretty darn amazing. We have glutathione, And here’s where your body’s taking glutathione and recycling it. But look who’s needed to recycle it. NADPH. So, if this guy up here is chewing it up, We don’t recycle our glutathione. And then an enzyme called glufon peroxidase 4, Takes this damaged lipid and repairs it. So, here we’ve got this protecting, we want to protect it by not having this happen. But then we also need this guy to do the restoration. So, there’s a lot that can go wrong in here, Dr. Deb. Dr. Deb Muth 00:37:07 There’s a lot that could go wrong. And I can imagine some of my listeners are thinking that lipid peroxidase, is that the same thing as what they’re thinking of when we talk about lipids and cholesterol? Is that the same process that’s happening there? Bob Miller 00:37:22 Well, no, no, the lipids can be used to make cholesterol, but here we’re talking about where they’re going to build the cell membrane. And they’re being… and they’re being, destroyed. If anybody would like to see a visual representation of this, just go on YouTube. And type in, ferrooptosis Animation. cool little video, it’s about 3 minutes long, and it shows the lipids coming over, being oxidized, and now GPX4 fixes them, so… YouTube, Pharaoptosis Animation, cute little video. It’s just that really… Shows vividly what we’re… what we’re talking about here. Now, this is… Dr. Deb Muth 00:37:59 And so this is very common, too. Like, a lot of people do hydrogen peroxide IVs. Dr. Deb Muth 00:38:04 And so, if somebody doesn’t know their genetics, they could have a problem with doing those, just like they could doing the NADHIVs, correct? Bob Miller 00:38:13 Sure, yeah, yeah, yeah. So, I’ve talked to so many, you know, of course, the hydrogen peroxide kills pathogens. I mean, that’s what it does. So… but I’ve spoken to so many people that said. I had one client that said they’ve never been the same after having one hydrogen peroxide infusion. Dr. Deb Muth 00:38:30 Interesting. Bob Miller 00:38:31 Yeah. So… it can be… I see why people use it, because it. Bob Miller 00:38:36 pathogens, But on the other hand. And now’s a good time to speak about… I don’t have it on here, but there’s a, there’s an enzyme called the HFE gene. And that is what causes you to absorb iron. And there’s mutations in it that cause something called hemochromatosis. Were you overabsorb iron? Now, true hemochromatosis is when both parents give you a mutation. But there’s now growing evidence even a heterozygous can cause a little bit more iron absorption, not to the human chromatosis point, but overabsorption. So, if you overabsorb iron, And you have too much hydrogen peroxide that’s not cleared, All kinds of inflammation. Now, what’s happened is sometimes this inflammation Will damage the red blood cells. And some well-meaning doctor says, oh, you need some iron. And they take iron and it makes it worse. So, can’t tell you how many people I’ve said, you’ve got the overabsorption of iron, and they say, well, that can’t be right, because I’m low in iron. Well, that could be because it’s being chewed up here. Dr. Deb Muth 00:39:40 Sure. GPX1 and TXN turn it into, to water. The, catalase turns it into water and oxygen. Dr. Deb Muth 00:39:58 Now, I see a lot of my clients who have mutations or SNPs on that GPX gene, on that glutathione gene. And they really struggle to clear a lot of their toxins. Bob Miller 00:40:12 Sure. Dr. Deb Muth 00:40:14 Yeah, absolutely. Well, GPX4. Bob Miller 00:40:18 is what, repairs, but you can see GPX1 Is what uses glutathione. To turn hydrogen peroxide. So, but it all depends upon having enough glutathione. Dr. Deb Muth 00:40:30 Yeah. Bob Miller 00:40:31 Well, guess who controls making a glutathione? Dr. Deb Muth 00:40:34 Nerf 2. Bob Miller 00:40:37 So, if you have a keep one weakness, or strength to two… I’m sorry, keep one is too strong. Nrf2 is too weak. You don’t make glutathione. So, when a lot of people do that, it’s like, well, I’m gonna take glutathione. Dr. Deb Muth 00:40:51 Right. Bob Miller 00:40:52 And some do great, and some do poorly. You know, because… and I’ll show this on one of the other charts. You can see here that the, The glutathione has to be recycled. And if we don’t recycle it, it actually turns into superoxide free radical. So… NADPH are the cofactors, For taking the oxidi… here’s oxidized glutathione, here’s reduced. So, this is a good glutathione. After it does its job, you can see it becomes oxidized.We need to recycle it. Well, if we have weakness on the enzyme that does that, or a weakness in Nrf2, or not enough NADPH. The oxidized glutathione never gets recycled. So, I’ve talked to a lot of people who said, oh, glutathione made me so sick, and say, well. Dr. Deb Muth 00:41:43 Yeah. Bob Miller 00:41:44 You need it, but you need to recycle it. Dr. Deb Muth 00:41:46 Can you speak for just a brief moment, too, about MTHFR? That is a very popular gene, it’s all over social media as the major gene, but can you speak to a little bit about that, and how that fits into this whole process of things? Because it is just such a small piece. Dr. Deb Muth 00:42:04 understanding genetics. Bob Miller 00:42:06 Yeah, to be honest, it drives me nuts. Dr. Deb Muth 00:42:08 Me too. Bob Miller 00:42:11 Alright, so… You know, there are people on social media I won’t say what I think, I’ll be kind. But… But the, And, you know, they might mean well. But they talk about, if you have MTHFR and COMT and PEMT, that’s… oh my goodness, that’s horrible, and we’ll fix that for you, and you’ll be fine. Bob Miller 00:42:36 it just irritates me to no end. And it really could get anybody who’s doing this legitimately in trouble. I mean, I’m afraid someday, you know, there might be some cracking down on this kind of nonsense. Now, to answer your question about MTHFR. Dr. Deb Muth 00:42:51 I mean, it really is, but I’ll tell you what, why don’t we hold that thought until I go to another map and I can actually… Okay. Bob Miller 00:42:56 But the real… the cliff notes is the MTHFR puts a methyl group on your folate, which is needed, but it has gotten way, way, way too much attention. And people learn they have MTHFR, and they start taking a multivitamin with methylfolate, then they take a B vitamin with methylfolate. Dr. Deb Muth 00:43:13 And they’re pushing it too hard. Bob Miller 00:43:15 Yeah. So I can’t tell you how many people I’ve helped by saying, stop it. Dr. Deb Muth 00:43:20 Yeah, take less of it. Bob Miller 00:43:21 Take less of it, yeah. So, yeah. Yeah, there’s a… If somebody, say, ranked the enzymes at their level of importance, MTHFR might be 40 or 50 on a scale of 100, you know. Keep one Nerf two. big deals. Dr. Deb Muth 00:43:40 deals. Bob Miller 00:43:41 NQO1 that I didn’t even talk about yet, NQO1, takes your, NA… your NAD goes into NADH, To make electrons for the electron transport chain. you need NQ01 to bring that back. If that’s not working, and I’ll show you on the NAD map how disastrous that can be. Now, the next piece is here, and I think You know, if you talk to any school teachers and say, if you’ve taught for more than 10 years, how are the kids today? Every one of them says, more ADD, ADHD, more autism. Just look at human beings, we’ve never been so agitated. You know, everybody, and it might be a social media thing, but people take a position on something, and if anybody doesn’t share that position, they view them as the enemy. Dr. Deb Muth 00:44:29 And it’s kind of scary what’s happening to us. Bob Miller 00:44:33 So, we can’t agree to disagree anymore. We see anybody who has a differing opinion as the enemy. And, you know, there was… there’s people that didn’t have Christmas dinners together, because they had political differences, like… Dr. Deb Muth 00:44:44 Excuse me. Bob Miller 00:44:45 can’t you put your political differences aside to have Christmas together, you know? Dr. Deb Muth 00:44:49 Right? Bob Miller 00:44:50 become that, you know, no matter what your position is, and I’m not saying anyone’s right or wrong, I’m just saying. You know, in the old days, they used to say that the Republicans and Democrats in Congress would argue policy and then go have dinner together. And now everybody’s all up in arms, angry. Dr. Deb Muth 00:45:05 Yeah. Bob Miller 00:45:06 So… There’s likely multiple reasons for that. But let me show you one of them. That, you know, to what degree this is… very important, we don’t know, but I think We’re beginning to believe this is very important. So, there’s something… there’s a neurotransmitter called GABA. And God buys the don’t worry, relax, be happy. Chill. Okay. Dr. Deb Muth 00:45:31 Nobody has enough of that anymore. Bob Miller 00:45:33 Well, yeah, you’ll be surprised what I’m gonna show you. So, let me see if I can find a, Let me see if I can find the right slide here. Let me look for it here. So, there’s something called a GABA receptor site. And here you can see… This is a neuron, and this is where you, The neuron normally is excitatory. However, there’s normally low chloride in the neuron. Dr. Deb Muth 00:46:09 Hmm. Bob Miller 00:46:10 So, GABA itself is neither relaxing. For excitatory, all GABA does, it opens up what’s called a chloride channel. And then chloride, which has a negative charge, will flow into the neuron. Follow me there? Dr. Deb Muth 00:46:26 Yep. Bob Miller 00:46:27 And as it does, it changes this from a positive charge to a negative charge, And it’s relaxing. and inhibitory. Dr. Deb Muth 00:46:34 Hmm. Bob Miller 00:46:36 Now, on the other hand, there’s enzymes called NKCC1, That will push chloride in. and KCC2 that will bring chlor… oops and bring chloride out. And then there’s a sodium channel. And, sodium has a positive charge. And glutamate will push that in. So, as long as this is happening. And GABA says, receptor sites, open, chloride goes in, Chill. However, If NKCC1 Pushes extra chloride in. KCC2 doesn’t pull it out. and GABA hits the receptor site, the GABA comes flowing out, Sodium comes in, And now it’s excitatory. So Gabba didn’t change. GABA just opened the receptor site, that’s all it does. Dr. Deb Muth 00:47:33 Yeah. Bob Miller 00:47:34 But it’s the chloride balance that’s going to determine whether this is relaxing or not. Now, these are the things that go along with when they lose that KCC2 or gain NKCC1. Pain and sensitivity, burning electrical, neuropathic pain. Normal touch hurts. Sound and light sensitivity. Tinnitus can flare. Headaches and migraines. Seizure tendency. Body jolts. Spasticity, cramps, stiffness, startle reflex. Trouble falling asleep, non-restorative sleep. Anxiety, stress, reactivity, that’s what we have now. Hyperarousal, panic-like surges, irritability, racing thoughts. Brain fog, slowed processing, working memory slip-ups. Mental fatigue. Episodes of racing hearts, sweaty palms, guts on edge. Those are all the things that happen when this GABA switch occurs. Now, here’s what happens, and this is what I’m going to be presenting at an autism conference. When you have a newborn, they need that NKCC dominant to develop. By early childhood, it should… or, sorry, early adulthood. we should move over to the KCC dominant, that’s the taking the chloride out. Nice-looking 25-year-old boys, functioning very well. However, when we get microglia M1 upregulated. Because of environmental toxins, processed foods, Tylenol, aluminum. they stay in NKCC1 dominant, and there’s ADD, ADHD, Autism, the whole spectrum. because… They’ve not moved over to the… They’ve not moved over to the KCC2. And again, this is caused by… Environmental factors. Stimulating the microglia. And then, interleukin-1, interleukin-18 weakens KCC2, interleukin-1 beta, Strengthens NKCC1. high chloride. We open up the chloride channel, In Rebell Excitatory. So, I think when, When the pediatricians get ahold of this, they’re going to be very excited to know that This could be why we’re seeing such a rise, and not just autism, but ADD, ADHD, anxiety, the whole shit mess. Dr. Deb Muth 00:49:58 thing. Bob Miller 00:49:59 Yeah, so… and you can see NF-kappa-B stimulates that. These stimulate it, and I think that’s why everyone’s getting so anxious. Now, there’s a little bit more to it, and we’ll get into this when we look at some of the maps, but… The, the glutamate, Which is excitatory. will stimulate the NMDA receptor, make more glutamate, And glutamate will inhibit KCC2. And then we also need an astrocyte To, take both ammonia And glutamate, and… Turn them back into glutamine. And I’m going to talk to you a little bit about arachidenic acid, and if we have too much arachidenic acid. or TNFA is upregulated, that doesn’t happen. Ammonia goes up, and there may be multiple reasons for this, but this is a reason why some of the autistic kids do flapping. Dr. Deb Muth 00:50:49 Hmm. Bob Miller 00:50:50 Because they’re not clearing their ammonia. And you can tell if somebody has high ammonia by… they get that old person smell, you know. Dr. Deb Muth 00:51:00 Yup. Bob Miller 00:51:01 your vehicle cycle’s not taking out the, the ammonia. Now, last pathway here. There’s growing interest in mast cell activation. So, back here, we talked about peroxynitride. And that will stimulate mast cells, and those are white blood cells that are your best friend, unless they’re your worst enemy. Then it’ll make histamine. And there’s enzymes called histidine decarboxylase that’ll make more. Dr. Deb Muth 00:51:28 I’m sure everybody’s heard of DAO, the enzyme that degrades histamine. Yep. Bob Miller 00:51:31 We can have genetic weakness, we don’t make that. There’s an enzyme called histamine and methyltransferase, That, That breaks down the histamine. Then if we don’t do that, it’ll get stuck in the histamine receptor site. And then it’ll make something called, renin. Which will cause angiotensinogen to turn into angiotensin. One, that turns into angiotensin II,And that’s where people make aldosterone, where they’ll get the, The swollen ankles and high blood pressure. But interestingly, there’s an enzyme called ACE2, that takes this guy and turns it into angiotensin 1-7, Which is anti-inflammatory and also inhibits… TNFA. Now, you can have weakness on ACE2, But… and anybody’s saying, that sounds familiar? Dr. Deb Muth 00:52:25 That’s where COVID comes in, using ACE2. Bob Miller 00:52:28 And now we just found there’s literature that if you get COVID long enough, it can actually make ACE2 not be able to work as well. So look what it does. It comes down here, stimulates the NADPH oxidase, More superoxide. More peroxynitrite. And we’re on a cycle here. We’ve actually named this the Home Cycle Hypothesis, the proposed feed-forward loop. That just keeps feeding on itself. All being caused by… Primarily, The environmental factors. But hitting those who have genetic weakness the hardest. That’s why. Dr. Deb Muth 00:53:08 To the people. Bob Miller 00:53:09 Don’t live in a moldy house. One person is sick as can be, and the other person says, well, you must be imagining things, because I don’t feel anything. Dr. Deb Muth Yeah. Same thing with long haul, right? Two people can both get sick, one gets sick and never seems to recover, and somebody else gets sick, and they have absolutely no problems with it at all. Bob Miller 00:53:30 Sure. Well, think about it, if you get COVID, and ACE2 is weak, and some of this other stuff is going on. This thing just starts feeding upon itself. Dr. Deb Muth 00:53:38 Keep creating more inflammation, more complications, nothing’s calming down. Bob Miller 00:53:43 Yeah. Now, you, you ask about, MTHFR. So, this is the, this is the, the software called Functional Genomic Analysis. There’s a demo report we have. So, let’s talk a little bit about, MTHFR. So, we actually have a map called a methylation map. Now, what happens is, when you do your saliva test, you, you know, you spit, you put some saliva. in a collection kit, goes to a lab, takes out the DNA data, sends it to the computer, and now you can actually see it visually. Okay. So, it’s gonna take a second for this, data to load up, it’s, and each of these Circles, each of these ovals, is an enzyme. And the data gets loaded up to see where it is. So, until it gets loaded up here, I didn’t preload this. There it goes. So… The primary thing about methylation is There’s a nasty substance called homocysteine that, if it’s too high, can really be detrimental. The body takes methylfolate, and combines with methyl B12, To bring this back up to methionine. And then through the MAT genes, we make SAMI, S-adml methionine. Which is involved in so many processes. Then after it does its thing, it turns back into homocysteine. And this thing needs to keep spinning around. That’s why, you know, it’s a good idea to keep homocysteine at, do you have a number that you’d like? 7, 8? What do you like for a number? Dr. Deb Muth 00:55:24 Yeah, I like mine below 7. Bob Miller 00:55:26 Yeah. So if the homocysteine goes too high. It, caused all kinds of problems. So, here’s where you ask about the MTHFR. So, here you can see on this individual. I click on MTHFR, and you can see it comes up here, here’s the C677. And you can see here where it says, variants. I’ll… I’ll draw in case somebody’s having a hard time seeing that. So, you can see there’s nothing in there. That means there’s no genetic mutations. If one parent would have given a mutation, there’d be a 1. If both parents did, there’d be a 2. Now, here’s why Yes, methylation is important, I’m not saying it isn’t important, but look at this MTHFRC677. In my software. Only 42.5% of the population does not have a mutation. 44.7% have won. 12.9 have 2. So, this isn’t some rare, oh my god, I’m gonna die… Kind of thing, yeah. Dr. Deb Muth 00:56:27 Right. Bob Miller 00:56:28 So, And then what happens is that, and again, I’m not dismissing methylation, I… we could do a whole show on methylation. Bob Miller 00:56:36 get it. But I think that what people are doing is they’re, they’re learning about MTHFR, they get it measured, they panic. They start taking massive amounts of methylfolate, which many times is to their detriment. Dr. Deb Muth 00:56:50 Well, it’s… and isn’t it true, too, with MTHFR, like, you have to also look at MTR, MTRR, and the more we stack up of those, the more complicated than MTHFR can be. It’s not… it’s not as simple as just saying MTHFR 677 versus 1298. It’s more complex than that, kind of like what you’ve already shown with some of the other things. There’s more to it than just that one little sliver. Bob Miller 00:57:17 Oh, sure, well, let’s take a look. So, remember I said there’s a cofactor? One of the cofactors is called FAD. Just a Bob Miller observation, that’s all. But when people have trouble with their riboflavin and they don’t have enough FAD, They’re doing much worse than people who have just a C677. So, right here, you could have perfect C677th. And if you don’t have the cofactor, it’s not gonna work, okay? Dr. Deb Muth 00:57:48 And as you said, there’s an MTR enzyme. Bob Miller 00:57:51 that takes methylfolate and methyl B12, to spin it around. So, here on this individual. here’s your… here’s your B vitamins, or I’m sorry, your B12s. There’s an enzyme called TCN1 that takes it from the stomach into the blood. Then there’s other enzymes that take it from the blood into the tissue. And if you’re having trouble here. Well, then you’re not going to have this working, so… Even if you don’t have MTHFR, And you have MTR, like this, no, I’m sorry, this person doesn’t. But they have the MTRR, and then they don’t have enough B12, this isn’t gonna work, aside from that. And then there’s a middle pathway. And then there’s enzymes called the MAT1. they take the methionine to the salmon. If that’s not working, we stick… we get stuck in methionine. So, it’s, it’s not just an MTHFR. And then, one of the things that people forget about. is through these CBS enzymes and CTH, We make cysteine, which is needed to make glutathione. The master antioxidant. So, it really is that… I call it the, The 3D chess game played underwater. Dr. Deb Muth 00:59:07 It really is. I mean, I see people who have CVS, COMT, glutathione, MGHFR genes. And some of them function just fine. Like, they have Like, I look at this person and I’m like, oh my gosh, I don’t know how they’re functioning because they’re double mutated on so many pathways, but yet they don’t have a lot of symptoms, they don’t have a lot of complications. Somehow their body has figured out a way to adapt to what it has so it can stay alive and it can function at a high functioning level. Bob Miller 00:59:36 Yeah, and they may be, you know, eating right? Yeah. Staying out of a moldy house. reducing stress. So, it’s diet, it’s stress, it’s genetics, environmental factors. So, yeah, we can’t just say somebody’s gonna be good or somebody’s gonna be bad. You know, some people get scared, oh, I got all these, it’s like, well… Bob Miller 00:59:56 Are you living in a moldy house? You know, and if you live in a moldy house and your glucuronidation pathway doesn’t do well, or if you’re, you know, a smoker, or you’re constantly eating junk food, I mean, all. Bob Miller 01:00:07 things come together. Although, you know, when we focus on genetics, we’re well aware that this is just a piece of it. You know, you could have identical twins, Genetically, and if one… Is exposed to mold and smokes and drinks and stressed out. They’re gonna be a whole lot sicker than their sibling. Bob Miller 01:00:28 Yep. Dr. Deb Muth 01:00:29 Yeah, it’s that concept of taking twins, and one gets raced with one family, and one gets raced with another family, and they don’t have the same… problems that… that each other have, you know? It’s a very unique situation, we don’t think about that enough. Bob Miller 01:00:44 Alright, so again, genetics loads the gun, environment pulls the trigger. So, if you’ve got a loaded gun, but you don’t have the triggers, you’re okay. Dr. Deb Muth 01:00:53 Yeah. Bob Miller 01:00:54 Yeah. So, remember I said I was going to talk about NAD? So, here’s NAD, and what it does, it turns into NADH. And what NADH does, it, Comes down this pathway, what’s called the electron transport chain. And that makes your ATP, that’s your energy. So, if this wasn’t working, we wouldn’t be alive, because we wouldn’t have energy. So it donates an electron, that’s why it’s called electron transport chain. So, we need NAD, To make this, to make the energy. But remember I said that NQ01, this would probably be, like, on my top 10 list of… Bob Miller 01:01:36 Much more important than MTHFR. This one takes NADH back to NAD. If we’re stuck over here, We’re low in this NAD+, But what happens is, NQO1 also provides CoQ10. And CoQ10 Is what’s needed for the electron transport chain to flow. So if we get too many electrons up here. And they don’t turn them into energy. They make a nasty free radical called superoxide. Okay. Now, NAD plus also makes NADPH, And that is needed. Remember I said we need to recycle our antioxidants. So, if we have a problem with FAD from riboflavin. Yeah, we don’t have enough NADPH, Glutathione’s not getting recycled, and you’re gonna be inflamed. And you take glutathione, you’ll feel worse. There’s another enzyme called thimoredoxin. Same thing, needs NADPH and FAD. And same way with your nitric oxide, there’s an enzyme called NOS3, That makes the nitric oxide that dilates your blood vessels. And if we don’t have enough NADPH or fat, You’re gonna make superoxide. Rather than nitric oxide. Now, remember

V., Saurat, N., Mehta, S., Garippa, R., Betel, D., Studer, L. Abstract: Ongoing, first-in-human clinical trials illustrate the feasibility and translational potential of human pluripotent stem cell (hPSC)-based cell therapies in Parkinson's disease (PD). However, a major unresolved challenge in the field is the extensive cell death following transplantation with less than 10% of grafted dopamine neurons surviving. Here, we performed a pooled CRISPR/Cas9 screen to enhance the survival of postmitotic dopamine neurons in vivo. We identified p53-mediated apoptotic cell death as a major contributor to dopamine neuron loss and uncovered a causal link of TNFa-NFkB signaling in limiting cell survival. As a translationally applicable strategy to purify postmitotic dopamine neurons, we performed a cell surface marker screen that enabled purification without the need for genetic reporters. Combining cell sorting with adalimumab pretreatment, a clinically approved and widely used TNFa inhibitor, enabled efficient engraftment of postmitotic dopamine neurons leading to extensive re-innervation and functional recovery in a preclinical PD mouse model. Thus, transient TNFa inhibition presents a clinically relevant strategy to enhance survival and enable the engraftment of postmitotic human PSC-derived dopamine neurons in PD.

P., Osuna-Almagro, L., Wu, M.-L., Johnson, C., Shah, A., Haskard, D. O., Buxton, A., Willis, E., Wheeler, K., Turner, S., Chlebicz, M., Scott, R., Kovats, S., Cleuren, A., Birdsey, G. M., Randi, A. M., Griffin, C. T. Abstract: Background: During infectious diseases, pro-inflammatory cytokines transiently destabilize interactions between adjacent vascular endothelial cells (ECs) to facilitate the passage of immune molecules and cells into tissues. However, in the lung the resulting vascular hyperpermeability can lead to organ dysfunction. Previous work identified the transcription factor ERG as a master regulator of endothelial homeostasis. Here we investigate whether the sensitivity of pulmonary blood vessels to cytokine-induced destabilization is due to organotypic mechanisms affecting the ability of endothelial ERG to protect lung ECs from inflammatory injury. Methods: Cytokine-dependent ubiquitination and proteasomal degradation of ERG was analyzed in cultured Human Umbilical Vein ECs (HUVECs). Systemic administration of TNFa or the bacterial cell wall component lipopolysaccharide (LPS) was used to cause a widespread inflammatory challenge in mice; ERG protein levels were assessed by immunoprecipitation, immunoblot, and immunofluorescence. Murine Erg deletion was genetically induced in ECs (Ergfl/fl;Cdh5(PAC)-CreERT2), and multiple organs were analyzed by histology, immunostaining, and electron microscopy. Results: In vitro, TNFa promoted the ubiquitination and degradation of ERG in HUVECs, which was blocked by the proteasomal inhibitor MG132. In vivo, systemic administration of TNFa or LPS resulted in a rapid and substantial degradation of ERG within lung ECs, but not ECs of the retina, heart, liver, or kidney. Pulmonary ERG was also downregulated in a murine model of influenza infection. Ergfl/fl;Cdh5(PAC)-CreERT2 mice spontaneously recapitulated aspects of inflammatory challenges, including lung-predominant vascular hyperpermeability, immune cell recruitment, and fibrosis. These phenotypes were associated with a lung-specific decrease in the expression of Tek, a gene target of ERG previously implicated in maintaining pulmonary vascular stability during inflammation. Conclusions: Collectively, our data highlight a unique role for ERG in pulmonary vascular function. We propose that cytokine-induced ERG degradation and subsequent transcriptional changes in lung ECs play critical roles in the destabilization of pulmonary blood vessels during infectious diseases.

A new research paper was published in Aging (listed as "Aging (Albany NY)" by MEDLINE/PubMed and "Aging-US" by Web of Science) Volume 15, Issue 1, entitled, “Genetic deficiency and pharmacological modulation of RORα regulate laser-induced choroidal neovascularization.” Choroidal neovascularization (CNV) causes acute vision loss in neovascular age-related macular degeneration (AMD). Genetic variations of the nuclear receptor RAR-related orphan receptor alpha (RORα) have been linked with neovascular AMD, yet its specific role in pathological CNV development is not entirely clear. In this new study, researchers Chi-Hsiu Liu, Felix Yemanyi, Kiran Bora, Neetu Kushwah, Alexandra K. Blomfield, Theodore M. Kamenecka, John Paul SanGiovanni, Ye Sun, Laura A. Solt, and Jing Chen from Harvard Medical School, UF Scripps Biomedical Research and University of Arizona showed that Rora was highly expressed in the mouse choroid compared with the retina, and genetic loss of RORα in Staggerer mice (Rorasg/sg) led to increased expression levels of Vegfr2 and Tnfa in the choroid and retinal pigment epithelium (RPE) complex. “Here, we investigated whether RORα regulates CNV using a mouse model of laser-induced CNV, mimicking the neovascular features of wet AMD. We found that expression of RORα was enriched in the mouse choroid/RPE complex and upregulated in laser-induced CNV.” In a mouse model of laser-induced CNV, RORα expression was highly increased in the choroidal/RPE complex post-laser, and loss of RORα in Rorasg/sg eyes significantly worsened CNV with increased lesion size and vascular leakage, associated with increased levels of VEGFR2 and TNFα proteins. Pharmacological inhibition of RORα also worsened CNV. In addition, both genetic deficiency and inhibition of RORα substantially increased vascular growth in isolated mouse choroidal explants ex vivo. RORα inhibition also promoted angiogenic function of human choroidal endothelial cell culture. “Together, our results suggest that RORα negatively regulates pathological CNV development in part by modulating angiogenic response of the choroidal endothelium and inflammatory environment in the choroid/RPE complex.” DOI: https://doi.org/10.18632/aging.204480 Corresponding Author: Jing Chen - jing.chen@childrens.harvard.edu Keywords: age-related macular degeneration, angiogenesis, choroidal neovascularization, inflammation, nuclear receptors, RORα, VEGFR2, TNFα Sign up for free Altmetric alerts about this article: https://aging.altmetric.com/details/email_updates?id=10.18632%2Faging.204480 About Aging-US: Launched in 2009, Aging (Aging-US) publishes papers of general interest and biological significance in all fields of aging research and age-related diseases, including cancer—and now, with a special focus on COVID-19 vulnerability as an age-dependent syndrome.

Gut Immune Body Brain Axis.Dr Gundry:Leaky Gut, gut microbiome and dietRenowned Cardiovascular Surgeon who realised that all he was doing was treating thesymptoms so he studied the underlying causes.The lining of the gut is one cell thickAs bacteria break down the gut that is when ageing startsIbuprofen or roundup disastrous the bacteria populationSkin is a mirror of the lining of the gutJoints do not naturally wear out.Animal model C Elegans as bacteria begin to break down the wall of the gut that is whenageing starts105 year old people have a diverse set of bugs identical to a healthy 30 year old. It is notattacking the wall of the gut.Ecermansia musinophilia. Lives in the mucous layer whose job is to trap lectins plantproteins looking for sugar molecules and to protect the wall of the gut from harmful bacteria.Ecermansia musinophilia eats mucus which in turn makes more mucus.Metformin works by increasing mucous and this change in bacteria makes some peoplehave mild diarrhoea as the bacteria change.If we damage this lining eg ibuprofen or food with roundup destroys the bacteria populationand gut lining.Glyocosade an antibacterial damages Ecermansia Musinophilia even though it does notdirectly affect human cells.Antibiotics in food or direct prescription eg ladies who take low dose for UTI have a higherincidence of heart disease.Heart disease is an autoimmune disease starting in the gut.Cholesterol is an innocent bystander which gets sucked into the inflamed wall of a bloodvessel.Infants with heart transplants have coronary artery disease with pathology identical withtypical coronary artery disease.Lectins which are a foreign protein which can stick to sugar molecules on the surface ofblood vessels are the cause of atherosclerosis and removing lectins reduces those markers.Lectins are one of the plant defence systems. Sticky proteins that look for specific sugarmolecules to stick to which insights an inflammtory response.Joints do not normally wear out. Usually you can find bacterial particles in the joint fluid ofarthritisBecauseLectins broke down the wall of the gut. 65% of the immune system is behind the wall of thegut because the gut is where the outside word gets through. A reason why we store fat inthe gut is to provide energy to the immune system. Similarly fat on the outside ofatherosclerotcic blood vessles correlates with the severity of inflammation.Fat is not the cause . It is there because of the inflammation and the inflammation is theredue to the leaky gut.The immune system responds to antigens on bacteria of viruses. Lectins have antigens withcross reactivity with other proteins in the body. Eg thyroid.Nightshade vegetables or peanutsLectins disrupt the microbiome and break up the lining of the gut allowing entry by lectinsand by bacteria or bacterial particles.Hence if you inject a bacterial lipopolysaccharide into a person you can induce septic shock.Alzheimers Parkinsons is neuroinflammation.Most amyloid is produced by bacteria in the gut. Therefore 40 billion dollars invested inantiamyloid drugs has been a waste because amyloid is produced by the amyloid producingbacteria inthe gut fet by western diet. Then the amyloid has to get through the wall of the gut.Once they get through the gut wall and goto the brain it will produce more amyloid.Cholesterol and amyloid coexist in dementia in those with the apoE gene.The apo E gene codes for a carrier molecule because it is less efficient at transportingcholesterol. It cannot get out of the cell after it has been attracted by inflammation.Faecal microbial transplant:1970s broad spectrum antibiotics came out which made it much quicker to treat infectionsbut it also wiped out the gut bacteria. Normally 10000 species of bacteria.Pseudomembranous colitis was caused by Clostridium Difficile over growing. Initial studydone from the faeces of medical students.Faecal enemas treated the pseudomembranous colitis.Meat with animals treated by antibiotics can also cause problems.60% of faeces is bacteriaOral microbiome and cloud of bacteria around us –Holobiome . This defines our personalspace.Kissing is a human and ape characteristic. Exchanging oral microbiome. Bacteria decidewhether the other person's bacteria are compatible with them.Women have a gut feeling because they are more capable of listening to their microbiome. We inherit our microbiome from our mother. All of the mitochondria are involved with bacteriainherited from our mother. Bacteria communicate to their ‘sisters 'ie the body's mitochondria.Autism: kids have a different microbiome than ‘normal'The placental microbiome is important in educating the foetal immune system.Oral faecal transplants for 6 weeks in autistic kids. Almost immediately 50% autismsymptoms reduced.Ecermansia like tubers, mushrooms, -study in Asia find 90% reduction in Alzheimers withtwo cups of mushrooms a week.Inulin containing compounds eg chicory, radicchio, jerusalem artichoke.Exercise women who exercise routinely from midlife have a 90% reduction in Alzheimers. Inthose who get AD it happens 11 years later. Housework can be important part of exercise.Meditation and yoga also changes the gut microbiome.Lymph system in the brain in deep sleep -early in the sleep cycle-shrinks by 20% and thesebad proteins are squeezed out. You need a 3-4 hour window between sleep and dinnerbecause blood flow diverts to the gut.Olive oil /walnuts / mediterranean low fat diet: first two groups improved memory after 5years. 3rd group lost memoryThose with CVD had a 30% reduction in events, the low fat group continued CVS events.Polyphenos in olive oil grow proteinsTMAO is made by gut bacteria primarily from animal protein especially choline eg egg yolkand carnitine . TMAO damages blood vessels. Polyphenols in certain olive oil and red winebalsamic vinegar that paralyse enzyme systems in the bacteria so they do not make TMAO.However the logical error here is that eggs which are high in choline are not associated withincreased morbidity.Vitamin D at least 5000 units a day . Almost all cancer patietns and autoimmune pateitnshave low vitamin D. HIgher your VItamin D the longer your telomere. Stem cells in the gutare simulated by vitamin D.VItamin CLectins are present in most plant foods but especially high in:legumes, such as beans, lentils, peas, soybeans, and peanutsnightshade vegetables, such as tomatoes and eggplantdairy products, including milkgrains, such as barley, quinoa, and riceThe Roll of Inflammation in Depression and FatigueFrontiers In Immunology:CH Lee 2019:Immune system link to depression first noticed with immunotherapy eg INFa (which activates an inflammatory antiviral response) for Hepatitis C : associated with raised proinflammatory cytokines and depression and fatigue.20% of patients treated with INFa developed depression which resolved on discontinuationbut also increased the risk of depression in future.Also people with higher IL6 aged 9 were more likely to have depression aged 18 in a dosedependent manner.Innate immune system seems to be lower in depression eg NK cells and also less antiinflammatory regulatory T cells whereas inflammatory monocytes are activated.There is commonality in immune activation from autoimmune disorder such as multiplesclerosis or immune reactions in sepsis.Antidepressants reduce inflammation while a higher baseline level of inflammation predicts apoorer treatment response.People with depression have been shown to have higher inflammatory markers which canbe used to predict treatment efficacy and future recurrences of depression.Elevated inflammatory markets eg TNFa after an MI disrupt the blood brain barrier causingdepression.Inflammatory changes in the brain with raised TNFa in the hippocampus and striatumprecede development of depressive symptoms.Neurogenesis is inhibited by the kynurenine pathway which is rescued by both inhibitors ofthis pathway and traditional antidepressants.TNFa also increases glutamate release causing exocytotic damage to surroundingsneurones.Conditions associated with chronic immune activation such as asthma, atopy, diabetes mMS, RhA, SLE are all associated with raised levels of depression eg 36% of asthma havedepression who also had higher TNFa than those who were not depressed. 75% in RhAMS up to 50% risk of depression.Acute inflammation with sepsis also causes depression and raises the risk of depression infuture which in animal models can be reduced by using steroid during the acute sepsis.Antidepressants reduce inflammatory markers perhaps SNRI more effective than SSRI andalso ECT adds in return to normal of NK activity.Directly reducing the immune response eg anti TNF a or Caspase Inhibitors have beenshown to reduce depression. Rituximab which is an antibody that targets and depletes Bcells in the treatment of RhA also reduces depression.Aspirin can reduce depression but can also reduce the effect of an SSRI.
Getting to the Heart of Cannabis Health Risks Cell Press Cannabis has deleterious effects on cardiovascular physiology. Wei et al. (Cell 185, May 12, 2022) confirm that important inflammatory markers increase transiently after a single marijuana joint and prove a mechanistic link between THC induced vascular inflammation, endothelial dysfunction, cellular oxidative stress, and atherosclerosis using cell-based and mouse models of atherosclerosis. They provide a pharmacological model in which THC-mediated activation of CB1 receptor signaling pathways converge on MAP kinase, TNFa, and NF-kB outputs to create a proinflammatory and atherogenic environment in endothelial cells. That genistein can antagonize the negative effects of THC with minimal central effects is exciting because genistein is a common component of soy and is already a widely consumed dietary product. Electronic Cigarettes Versus Nicotine Patches for Smoking Cessation in Pregnancy: A Randomized Controlled Trial Nature Medicine Pregnant smokers were randomized to use either nicotine replacement therapy with patches (NRT, n=571) or e-cigarettes (n=569) for smoking cessation. For the primary outcome, validated prolonged quit rates at the end of pregnancy, the results were 4.4% for NRT and 6.8% for e-cigarettes (P=0.08). However, 25 participants in the NRT arm who reported abstinence also used e-cigarettes. When these participants were excluded from data analysis the quit rates were 3.6% for NRT and 6.8% for e-cigarettes (P=0.02). Low birthweight was less common in the e-cigarette arm, 9.6% versus 14.8% for NRT (P=0.01). The authors conclude that “e-cigarettes were markedly more effective than patches” and do not pose more risk. Daily Cannabis Use, Cannabis Use Disorder, and Any Medical Cannabis Use Among US Adults: Associations Within Racial, Ethnic, and Sexual Minoritized Identities in a Changing Policy Context Preventive Medicine Reports Cannabis use has steadily increased in the United States, with daily and medical use associated with cannabis use disorder (CUD) and the negative consequences more frequent among marginalized groups. In this study, the authors use the National Survey on Drug Use and Health (NSDUH) to examine medical and daily use and CUD across the intersections of racial, ethnic, and sexual minorities. They found that sexual minorities were more likely to have medical and daily use and CUD than their heterosexual counterparts within each racial and ethnic group. However, when examining the intersection of race, ethnicity and sexual identity, there was more heterogeneity across these groups. In addition, they found that in states with medical cannabis laws (MCL) daily cannabis use was higher across all intersectional groups. Effect of AXS-05 (Dextromethorphan-Bupropion) in Major Depressive Disorder: A Randomized Double-Blind Controlled Trial AJP Psychiatry Altered glutamatergic neurotransmission is implicated in the pathogenesis of major depressive disorder. AXS-05 (dextromethorphan-bupropion) is an oral NMDA receptor antagonist and sigma-1 receptor agonist, which utilizes inhibition of CYP2D6 to increase its bioavailability. This phase 2 trial assessed the efficacy and safety of dextromethorphan-bupropion in the treatment of major depressive disorder. In patients with major depression, dextromethorphan-bupropion (AXS-05) significantly improved depressive symptoms compared with bupropion and was generally well tolerated. The most common adverse events were dizziness, nausea, dry mouth, decreased appetite, and anxiety. Dextromethorphan-bupropion was not associated with psychotomimetic effects, weight gain, or sexual dysfunction. Mental Health and Substance Use Among Homeless Adolescents in the US JAMA Network This study evaluated mental health and substance use outcomes among homeless and non-homeless adolescents in 2019. Alcohol, cigarette, marijuana, and binge drinking during the prior 30 days was assessed, along with lifetime use of cocaine, methamphetamine, heroin, ecstasy, and injection drugs or prescription opioid misuse. Results found current substance use ranging from cigarettes to alcohol were higher among homeless adolescents. Lifetime cocaine use was significantly higher among homeless adolescents, as were methamphetamine, heroin, ecstasy, and injection drug use. Homeless adolescents experience worse mental health outcomes, including depression and suicidality, and struggle with more SUDs than their counterparts. The Importance of Federal Action Supporting Overdose-Prevention Centers NEJM In this prospective piece, the authors discuss the need for new approaches to harm reduction and substance use disorder treatment in the face of substantially increasing overdose deaths, particularly since the start of the COVID-19 pandemic. One such strategy they discuss is overdose-prevention centers, which operate in other countries and are associated with significant reductions in opioid-overdose morbidity and mortality. However, under Section 856 of the Controlled Substances Act, such facilities may be subject to federal legal sanctions. The authors recommend that the Biden administration declare they will not interfere with such public health interventions or declare that section 856 does not apply to legally sanctioned centers. Further, Congress should modify the Controlled Substance Act to exempt overdose-prevention centers. Complex Persistent Benzodiazepine Dependence—When Benzodiazepine Deprescribing Goes Awry JAMA Psychiatry Benzodiazepines remain popular medications among patients due to rapid symptom relief and reinforcing effects. As clinicians and patients become more aware of potential risks, and clinical guidelines increasingly urge caution in prescribing, guidance for benzodiazepine deprescribing is needed. The authors propose a new clinical concept for patients experiencing significant psychological or functional decline during or after a benzodiazepine taper—complex persistent benzodiazepine dependence (CPBD). CPBD can be described as symptomatic or functional decompensation with or without the development of aberrant medication behaviors in the setting of benzodiazepine deprescribing–in the absence of a benzodiazepine use disorder. Further research is needed to validate this concept. What is Success in Treatment for Opioid Use Disorder? Perspectives of Physicians and Patients in Primary Care Settings JSAT Opioid abstinence and treatment retention are typically used as measures of success of MOUD treatment. This study sought to identify other important treatment outcomes and patient-centered measures of success. Qualitative, structured interviews were conducted with physicians (n=14) and patients (n=18) in 2 family medicine residency programs. The physicians (7 faculty and 7 residents) were experienced buprenorphine prescribers. Both patients and physicians identified 5 themes: staying sober, and improvement in physical health, mental health, relationships, and role functioning. Patients, but not physicians, identified 2 additional themes: tapering off buprenorphine, and decreased stigma and shame. The authors conclude that “clinicians and researchers need to consider a broader scope of success indicators.”
These tests are required if you want to test for inflammation in your body. These tests check for systemic or whole body inflammation. Inflammation is something that you don't want going on in your body. High levels of inflammation in the body increase your risk of developing almost every major disease including autoimmune disease, cancer, heart disease, stroke, and much more. Inflammation has also been associated with accelerated aging! No matter how you look at it, it's not something you want in your body. The good news is that you can test for inflammation in your body by looking at some simple blood tests. These blood tests help identify the presence of both acute and chronic inflammation but they don't tell you WHY the inflammation is present. These tests are so important that I order them in just about every patient that I see. They are especially helpful if you have thyroid problems or just want to stay in optimal health. These tests include: - ESR - CRP - Ferritin - Antibody testing (optional) - IL6, TNFa, and fibrinogen (optional) Learn why these tests are so important and what they mean for you in this video.

There are a ton of "functional" labs out there today. In this podcast, I cover the most important labs for managing autoimmunity. If there is one takeaway from this episode, it is: FOCUS ON THE BASICS FIRST! So often someone brings me in a fancy methylation panel, hormone panel, or stool sample and they don't know their basics. I divide these labs into 3 categories:1. Basics - Basic blood markers are the foundation, and often people have them from multiple practitioners and you can compare apples to apples. These include CBC and CMP (which I discuss how important these are!), iron/TIBC, ferritin, homocysteine, vitamin D, thyroid markers, LDH, HbA1C, inflammatory markers like CRP, TGFbeta, GlycA, TNFa, and more. 2. Autoimmune-Specific Tests - antibodies including ANA, thyroid, rheumatoid factor, gut tissue, neurological tissue; barrier integrity such as gut barrier and blood-brain-barrier; advanced immune tests such as T & B Lymphocytes. In this section I give a special focus to Cyrex labs, who is in my opinion the leader in autoimmune reactivity testing. 3. Drivers - Foods, Toxins, Stress, Hormones, and Hidden Infections. This includes food sensitivities, stool testing, toxin testing, and more. I discuss some of my favorites, which include Cyrex again, Great Plains, GI Map, Dried Urine Hormones from Meridian Valley, and more.
Rheumatology describes 'aches & pains' which really includes over 200 autoimmune (and auto-inflammation- what is this?! Listen in!) diseases and, since HIV-AIDs blew open the doors on research into re-discovering the immune system, now includes science ranging from tolerance to the trillions that live in and on us as our microbiome, cancer, autoimmune disease, auto-inflammation (like with chronic inflammatory response syndrome), allergies and mast cell activation, and pathogenic and/or sub-occult infections. What a 'specialty’! In today’s Podcast for Healing Neurology episode, classically-trained and triple-board certified (internal medicine, pediatrics and rheumatology) physician, Anthony Padula, brings his experience to bear on this complicated topic. Gain insight into some of the pharmacology history, like how TNFa medications were 'designed' to treat sepsis (severe infection) but resulted in elevated mortality and then were found useful for inflammation in other realms. It's similar for methotrexate designed to treat cancer can be useful as a once weekly treatment for autoimmune disease. This is foundational information we need to better understand how to address our immune system, with all of the current-day 'new' triggers like light, noise and heavy metal pollution, like microplastics in our air and water (and baby bottles-ugh!) and so many others to which we haven't evolved. It's these 'vague' irritants that can light up our system and persist chronic disease.

Abstract: Traumatic spinal cord injury (SCI) produces a complex syndrome that is expressed across multiple endpoints ranging from molecular and cellular changes to functional behavioral deficits. Effective therapeutic strategies for CNS injury are therefore likely to manifest multi-factorial effects across a broad range of biological and functional outcome measures. Thus, multivariate analytic approaches are needed to capture the linkage between biological and neurobehavioral outcomes. Injury-induced neuroinflammation (NI) presents a particularly challenging therapeutic target, since NI is involved in both degeneration and repair. Here, we used big-data integration and large-scale analytics to examine a large dataset of preclinical efficacy tests combining 5 different blinded, fully counter-balanced treatment trials for different acute anti-inflammatory treatments for cervical spinal cord injury in rats. Multi-dimensional discovery, using topological data analysis (TDA) and principal components analysis (PCA) revealed that only one showed consistent multidimensional syndromic benefit: intrathecal application of recombinant soluble TNFa receptor 1 (sTNFR1), which showed an inverse-U dose response efficacy. Using the optimal acute dose, we showed that clinically-relevant 90 min delayed treatment profoundly affected multiple biological indices of NI in the first 48 hrs after injury, including reduction in pro-inflammatory cytokines and gene expression of a coherent complex of acute inflammatory mediators and receptors. Further, a 90 min delayed bolus dose of sTNFR1 reduced the expression of NI markers in the chronic perilesional spinal cord, and consistently improved neurological function over 6 weeks post SCI. These results provide validation of a novel strategy for precision preclinical drug discovery that is likely to improve translation in the difficult landscape of CNS trauma, and confirm the importance of TNFa signaling as a therapeutic target.

Abstract: Previous studies demonstrated that retinal damage correlates with a massive remodeling of extracellular matrix (ECM) molecules and reactive gliosis. However, the functional significance of the ECM in retinal neurodegeneration is still unknown. In the present study, we used an intraocular pressure (IOP) independent experimental autoimmune glaucoma (EAG) mouse model to examine the role of the ECM glycoprotein tenascin-C (Tnc). Wild type (WT ONA) and Tnc knockout (KO ONA) mice were immunized with an optic nerve antigen (ONA) homogenate and control groups (CO) obtained sodium chloride (WT CO, KO CO). IOP was measured weekly and electroretinographies were recorded at the end of the study. 10 weeks after immunization, we analyzed retinal ganglion cells (RGCs), glial cells and the expression of different cytokines in retina and optic nerve tissue in all four groups. IOP and retinal function was comparable in all groups. Although less severe in KO ONA, WT and KO mice displayed a significant loss of RGCs after immunization. Compared to KO ONA, a significant reduction of {beta}III-tubulin stained axons and oligodendrocyte markers was noted in the optic nerve of WT ONA. In retinal and optic nerve slices, we found an enhanced GFAP+ staining area of astrocytes in immunized WT. In retinal flat-mounts, a significantly higher number of Iba1+ microglia was found in WT ONA, while a lower number of Iba1+ cells was observed in KO ONA. Furthermore, an increased expression of the glial markers Gfap, Iba1, Nos2 and Cd68 was detected in retinal and optic nerve tissue of WT ONA, whereas comparable levels were observed in KO ONA post immunization. In addition, pro-inflammatory Tnfa expression was upregulated in WT ONA, but downregulated in KO ONA. Vice versa, a significantly increased anti-inflammatory Tgfb expression was measured in KO ONA animals. Collectively, this study revealed that Tnc plays an important role in glial and inflammatory response during retinal neurodegeneration. Our results provide evidence that Tnc is involved in glaucomatous damage by regulating retinal glial activation and cytokine release. Thus, this transgenic EAG mouse model offers for the first time the possibility to investigate IOP-independent glaucomatous damage in direct relation to ECM remodeling.

Activation of immune cells is the all-important first step in mounting an immune response. Immune cell activation is a popular area of research because so much happens that is key to the downstream goal of fighting infection, cancer, and disease. There are many ways to measure immune cell activation, and they all have utility. Methods can be grouped into four main categories: Proliferation Assays, Cytokine Measurement, Surface Antigen Expression, and Cytotoxicity. In this webinar, we'll discuss specific assays in each of these categories, the joys and pitfalls of each assay, and recommendations on how to choose the best method. You will learn tips and strategies for successful assay development using the following methods: Proliferation: - 3H-Thymidine Uptake - Bromodeoxyuridine Uptake (BrdU) - ATP Luminescence - Fluorescent Dye Reduction (CFSE) Cytokine Measurement: - Multiplex vs. Single Cytokine - Choice of Cytokine (IFNg, TNFa, IL-6, IL-1?, etc.) - Kinetics of Cytokine Release Surface Antigen Expression: - CD69, CD25, PD-1, etc. - Combine with CFSE, Ki67 or BrdU - Kinetics are Important Cytotoxicity: - Two-Label Flow Cytometry - Calcein AM Dye Release - Luciferase Transduced Targets - Annexin V

Gallensäuren stellen potente Signalmoleküle dar, die schon in geringen mikromolaren Konzentrationen, wie sie beim Menschen im Serum beobachtet werden, zentrale Leberzellfunktionen auf transkriptioneller und posttranskriptioneller Ebene beeinflussen. Die hydrophoben und potentiell toxischen Gallensäuren Lithocholsäure (LCA) und Chenodeoxycholsäure (CDCA) induzieren Apoptose und Cholestase, während hydrophile Gallensäuren hepatoprotektiv wirken können. Unter ihnen ist die antiapoptotisch und anticholestatisch wirksame Ursodeoxycholsäure (UDCA) von besonderer Bedeutung. UDCA stellt derzeit das einzige wirksame Therapeutikum bei chronischen cholestatischen Leberkrankheiten dar. Die vorliegende Arbeit untersuchte die Bedeutung intrazellulärer Signaltransduktionswege für die choleretischen, (anti-)cholestatischen und (anti-)apoptotischen Wirkungen physiologischer Gallensäuren in verschiedenen experimentellen Modellen. Hauptziel der Arbeit war die genauere Charakterisierung (i) der für den klinisch bedeutenden anticholestatischen Effekt des Taurinkonjugats der Ursodeoxycholsäure (TUDCA) verantwortlichen Signaltransduktionswege, und (ii) der zentralen Stellung von PI3-Kinasen in der intrazellulären Signalvermittlung der biologischen Effekte hydrophiler und hydrophober Gallensäuren. Im Modell der isoliert perfundierten Rattenleber untersuchten wir die anticholestatische und hepatoprotektive Wirkung der TUDCA in der intakten Leber unter Einsatz pharmakologischer Enzyminhibitoren. Als Leberfunktionsparameter dienten quantitativer Gallenfluß, Sekretion des Modellsubstrats der Konjugatexportpumpe Mrp2, GS-DNP, in die Galle und als Marker der Leberzellschädigung die hepatovenöse LDH-Freisetzung. Simultane Hemmung der cPKCa und der PKA, nicht aber Hemmung von cPKCa oder PKA allein antagonisierte bei Taurolithocholsäure (TLCA)-induzierter Cholestase die protektive Wirkung der TUDCA. Gallenfluß und GS-DNP-Sekretion waren unter gleichzeitiger Hemmung beider Signalwege signifikant reduziert, wohingegen die LDH-Freisetzung deutlich erhöht war. Die Ergebnisse zeigen, dass der posttranskriptionell vermittelte anticholestatische Effekt der TUDCA im etablierten Modell TLCA-induzierter Cholestase durch einen kooperativen cPKC- und PKA-abhängigen Signalweg vermittelt wird. Mitogenaktivierte Proteinkinasen Erk1/2- und p38-abhängige Signalwege hingegen, die als Vermittler von TUDCA-induzierter Cholerese unter nicht-cholestatischen Bedingungen beschrieben wurden, waren im untersuchten Modell ohne Bedeutung für die anticholestatische Wirkung der TUDCA. Mit Hilfe der neu etablierten Biotinylierung von Membranproteinen konnten wir in Ntcp-transfizierten humanen Hepatomzellen (HepG2-Ntcp) zeigen, dass TUDCA unter Cholestase die Insertion von MRP2 in die Hepatozytenmembran anregt. Dieser für die klinische Wirksamkeit der (T)UDCA potentiell bedeutende und im Tiermodell von uns vorbeschriebene Wirkmechanismus konnte damit erstmals in einem humanen Modell nachvollzogen werden. Ein weiterer in vitro Ansatz untersuchte die Phosphorylierung von aus HepG2-Ntcp immunopräzipitiertem MRP2 durch die als Gallensäureneffektoren diskutierten Proteinkinasen cPKCa, nPKCe und PKA. Alle drei Proteinkinasen phosphorylierten, durch den PKC/PKA-Inhibitor Staurosporin hemmbar, MRP2. Diese Phosphorylierung könnte, wie für die Gallensäurentransporter BSEP und NTCP bereits gezeigt, Einfluss auf Aktivität und Membraninsertion von MRP2 haben. Der funktionellen Bedeutung der PI3-Kinasen, welchen in den bisher entschlüsselten Signalwegen sowohl hydrophober/toxischer wie auch hydrophiler/protektiver Gallensäuren eine zentrale Rolle zugesprochen worden war („PI3-Kinasen-Paradoxon“), galten unsere in vitro Untersuchungen zur Aktivität der Isoformen der Klasse I PI3-Kinasen p110a, p110b und p110g nach Stimulation von primären Rattenhepatozyten mit TLCA, GCDCA, TCA und TUDCA in einem neu etablierten isoformspezifischen Kinaseassay. Dabei zeigte sich für jede Gallensäure ein für sie spezifisches Aktivierungsmuster unterschiedlicher PI3-Kinase-Isoformen. PI3-Kinase p110g wurde dabei spezifisch durch die cholestatisch und apoptotisch wirkenden Gallensäuren TLCA und GCDCA aktiviert. In HepG2-Ntcp-Zellen untersuchten wir daher die Bedeutung von p110g für Gallensäuren-induzierte Apoptose nach deren pharmakologischer Hemmung bzw. nach Transfektion mit siRNA gegen p110g. Die apoptotische Wirkung u.a. der Gallensäuren TLCA und GCDCA war unter beiden Methoden der p110g-Antagonisierung deutlich reduziert, wie sowohl in einem Caspase3/7-Assay als auch morphologisch evaluiert. Gallensäuren-unabhängige Apoptose, durch Etoposid bzw. TNFa ausgelöst, war p110g-unabhänig. Die Bedeutung der Aktivierung der PI3-Kinase-Isoform p110a durch TUDCA ist durch weitere experimentelle Untersuchungen zu klären. Die Erkenntnisse der vorliegenden Arbeit tragen zum Verständnis der komplexen Signalgebung im Rahmen cholestatischer Leberschädigung und der therapeutischen Wirkung der (T)UDCA bei und sind damit für die Entwicklung neuer Therapiestrategien bei cholestatischen Leberkrankheiten potentiell von Bedeutung.
Objectives: To study the clinical outcome, treatment response, T-cell subsets and functional consequences of a novel tumour necrosis factor (TNF) receptor type 1 (TNFRSF1A) mutation affecting the receptor cleavage site. Methods: Patients with symptoms suggestive of tumour necrosis factor receptor-associated periodic syndrome (TRAPS) and 22 healthy controls (HC) were screened for mutations in the TNFRSF1A gene. Soluble TNFRSF1A and inflammatory cytokines were measured by ELISAs. TNFRSF1A shedding was examined by stimulation of peripheral blood mononuclear cells (PBMCs) with phorbol 12-myristate 13-acetate followed by flow cytometric analysis (FACS). Apoptosis of PBMCs was studied by stimulation with TNFa in the presence of cycloheximide and annexin V staining. T cell phenotypes were monitored by FACS. Results: TNFRSF1A sequencing disclosed a novel V173D/ p.Val202Asp substitution encoded by exon 6 in one family, the c.194–14G.A splice variant in another and the R92Q/p.Arg121Gln substitution in two families. Cardiovascular complications (lethal heart attack and peripheral arterial thrombosis) developed in two V173D patients. Subsequent etanercept treatment of the V173D carriers was highly effective over an 18-month follow-up period. Serum TNFRSF1A levels did not differ between TRAPS patients and HC, while TNFRSF1A cleavage from monocytes was significantly reduced in V173D and R92Q patients. TNFa-induced apoptosis of PBMCs and T-cell senescence were comparable between V173D patients and HC. Conclusions: The TNFRSF1A V173D cleavage site mutation may be associated with an increased risk for cardiovascular complications and shows a strong response to etanercept. T-cell senescence does not seem to have a pathogenetic role in affected patients.

The cardiovascular hormone ANP is known to exert anti-inflammatory properties in macrophages and endothelial cells. This work provides new insight into the inflammatory signalling pathways influenced by the ANP in the lung. For these purposes, the effects of ANP on both alveolar epithelial cells and a model of LPS-induced lung inflammation were characterized. In alveolar epithelial cells, ANP was shown to inhibit the activation of two major transcription factors, NF-kB and AP-1, in response to TNFa. Astonishingly, this did not result in a reduced expression of the adhesion molecule ICAM-1. ANP was also capable to diminish the activation of AP-1 and NF-kB in lung tissue in vivo using a mouse model of LPS-induced septic shock. The inhibition of NF-kB activation was caused by a delayed phosphorylation and subsequent degradation of IkBa. In addition, ANP treatment elevated total protein levels of IkBa. p38 MAPK and Akt are important mediators in LPS-induced signalling. We demonstrated an activation of these kinases in lung tissue in response to i.p. LPS challenge. ANP treatment was able to lessen this activation. Furthermore, exclusive ANP treatment resulted in an increased p38 MAPK activation, which might contribute to the observed impact on other pathways. ICAM-1 expression was not impaired in whole lung tissue. ANP strongly decreased TNFa serum levels dose-dependently, but had only a slight effect on TNFa tissue levels. Interestingly, TNFa mRNA expression was not significantly reduced. Taken together this work demonstrates that ANP is able to diminish several important inflammatory pathways which are involved in the development of acute respiratory distress syndrome in LPS-induced sepsis.

Diese Dissertation handelt von der TNFa Freisetzung von isoliert, reperfundierten Mäuseherzen nach 15 min Ischämie und 90 min Reperfusion im Vergleich zu normoxisch perfundierten Mäuseherzen. Zudem sollte mit Hilfe von k.o.-Mäusenherzen und pharmakologischen Interventionen versucht werden, Rückschlüsse auf den zellulären Ursprungsort des TNFa zu bekommen und über dessen Freisetzungsmechanismus. TNFa wird nach 15 min Ischämie in zwei Phasen während der Reperfusion freigesetzt: direkt nach der Ischämie und nach 60-90 min. Normoxisch perfundierte Herzen zeigten dagegen einen Basaltonus des TNFa von 1,5pg/min über den gesamten Versuchsablauf. Der erste Gipfel der TNFa Freisetzung konnte als rein kinetisches Phänomen -wash-out- identifiziert werden, während es sich beim zweiten Gipfel um eine de-novo Synthese des TNFa handelt. Interleukin-6 und die Matrix-Metalloprotease-7 sind essentielle Faktoren für die TNFa Freisetung nach 60-90 min. Mastzellen können als Ursprungszelle des zweiten Gipfels ausgeschlossen werden.Sie sind neben Makrophagen und Endothelzellen am Basaltonus der TNFa Freisetzung beteiligt.

During my PhD thesis I was working on the identification of novel apoptosis-inducing genes by using a novel genetic expression screen (Grimm and Leder, 1997). One of the identified genes turned out to be a evolutionary conserved cDNA that codes for a novel BH3-only protein of 219 amino acid residues which was named Spike, for Small protein with inherent killing effect. Spike was then in the course of my PhD thesis extensively characterised, molecularly and biochemically. In summary, upon overexpression in mammalian cells Spike efficiently leads to all features of apoptosis, such as phenotypic alterations, cytochrome c release, caspase activation and DNA degradation. It was shown that Spike localised to the endoplasmic reticulum, where it interacts with a recently identified apoptosis regulating protein complex, consisting of Bap31, Bcl-2, Bcl-XL and an ER-specific isoform of caspase-8: pro-caspase 8L (Breckenridge et al. 2002). Although no direct interaction with anti-apoptotic members of the Bcl2-family could be observed, the importance of the BH3-like sequence for the apoptosis-inducing activity of Spike was demonstrated by using point mutations of conserved amino acid residues of this motif (Mund et al. 2003). Instead of directly interacting with anti-apoptotic members of the Bcl-2 family Spike is able to interfere with the complex formation between Bap31 and Bcl-XL. Based on these data I proposed a model according to which the complex on Bap31 is controlled by Bcl-2/Bcl-XL as long as they are associated. Displacement of Bcl-2/Bcl-XL from Bap31 by Spike leads to the formation of a pro-apoptotic complex. In addition, Spike appears to be implicated in the cell death signal of the Fas receptor. I observed that a dominant-negative version of Spike and a highly effective anti-sense oligonucleotide significantly reduced Fas-mediated DNA fragmentation whereas no reduction was detected in TNFa-induced cell death (Mund et al. 2003).
Primary biliary cirrhosis (PBC) is considered an autoimmune disease characterized by destruction of small intrahepatic bile ducts by lymphocytes. Altered functions of these lymphocytes might reflect an abnormal immune response leading to tissue damage. We investigated lymphokine secretion by mitogen-stimulated T lymphocytes from the liver biopsies of patients with PBC and for comparison also peripheral blood. In PBC, diminished synthesis of lymphotoxin (TNFP), tumor necrosis factor (TNFa) and interferon-y (IFIVy) was found both in T-cell lines from liver tissue and in peripheral blood. The reduction was most prominent for TNFP in early histological stages of PBC, and appeared to be a stable phenomenon when T cells were tested after long-term tissue culture. Analysis of mRNA levels indicates a possible link between reduced TNFP production and a defect in interleukin-2 transcription. The data suggest that diminished lymphokine production in patients with PBC may play ;In important role in the immanopathogenesis of this disease.
