Fungal diseases are becoming more common, more dangerous, and more difficult to treat. There's concern that they may cause the next global pandemic. Rising global temperatures, better survival rates for vulnerable patients, and increased medical interventions contribute to the rise in fungal infections. Access to effective diagnostics and treatment remains limited, with significant disparities between high and low-income countries. Treating fungal infections is becoming more challenging as they build resistance to the drugs used to treat them. New therapies are being developed, including treatments that disrupt fungal DNA replication or interfere with essential proteins, offering some hope for long-term control.Contributors: Adilia Warris, Professor in Paediatric Infectious Diseases, University of Exeter, UKRita Oladele, Professor of Clinical Microbiology, University of Lagos and Lagos University Teaching Hospital, NigeriaArturo Casadevall, Professor and Chair of Molecular Microbiology and Immunology, Johns Hopkins Bloomberg School of Public Health, USMichael Bromley, Professor in Fungal Disease, University of Manchester, UKPresenter: Tanya Beckett Producer: Louise Clarke Researcher: Maeve Schaffer Editor: Tara McDermott Technical Producer: Richard Hannaford Production co-ordinator: Tammy Snow(Image: Aspergillus fumigatus, seen under an optical microscope.

Sabina Kaczanowska's research focus is to understand the role of the immune system in shaping the microenvironment of metastasis during cancer progression. Specifically, she is investigating how myeloid cells orchestrate the immunosuppressive program in the pre-metastatic niche and how we can apply this knowledge of myeloid biology to design new immunotherapeutic strategies for the treatment of solid tumors. She joined us on OsteoBites to discuss her recently published paper on Immune determinants of CAR-T cell expansion in solid tumor patients receiving GD2 CAR-T cell therapy.https://pubmed.ncbi.nlm.nih.gov/38134936/Chimeric antigen receptor T cells (CAR-Ts) have remarkable efficacy in liquid tumors, but limited responses in solid tumors. The NCI conducted a Phase I trial (NCT02107963) of GD2 CAR-Ts (GD2-CAR.OX40.28.z.iC9), demonstrating feasibility and safety of administration in children and young adults with osteosarcoma and neuroblastoma. Patient samples were evaluated by multi-dimensional proteomic, transcriptomic, and epigenetic analyses. The data uncover mediators of CAR-T biology and correlates of expansion that could be utilized to advance immunotherapies for solid tumor patients.https://clinicaltrials.gov/study/NCT02107963Dr. Sabina Kaczanowska received her Ph.D. in Molecular Microbiology and Immunology from the University of Maryland, Baltimore for her dissertation work on T-cell immunotherapy at the UM Marlene and Stewart Greenebaum Comprehensive Cancer Center. She joined the Tumor Microenvironment and Metastasis Section of the Pediatric Oncology Branch at the National Cancer Institute as a postdoctoral fellow in 2017 with Dr. Rosandra Kaplan. Dr. Kaczanowska was appointed as a Staff Scientist in the Pediatric Oncology Branch in 2022 to continue her work evaluating the responses of solid tumor patients to immunotherapy and translating new immuno-oncology approaches into the clinic.

Dr. Emma Allen-Vercoe is back for a second episode and we chat about the influence of probiotics and antibiotics on the gut microbiome. Could there be missing microbes contributing to food intolerances? And why researching the microbiomes of honey bees is helping our understanding of their survivability and social behaviors. Dr. Emma Allen-Vercoe obtained her BSc (Hons) in Biochemistry from the University of London, and her PhD in Molecular Microbiology through an industrial partnership with Public Health England. Emma started her faculty career at the University of Calgary in 2005, with a Fellow-to-Faculty transition award through CAG/AstraZeneca and CIHR, to study the normal microbes of the human gut. In particular, she was among the few that focused on trying to culture these ‘unculturable' microbes in order to better understand their biology. To do this, she developed a model gut system - the Robogut - to emulate the conditions of the human gut and allow communities of microbes to grow together, as they do naturally. Emma moved her lab to the University of Guelph in late 2007, and has been a recipient of several Canadian Foundation for Innovation Awards that have allowed her to develop her specialist anaerobic fermentation laboratory further. This has been boosted by the award of a Tier 1 Canada Research Chair in Human Gut Microbiome Function and Host Interactions. Emma's research focuses are very broad, although they are all united under the banner of microbial culture and the microbiome. She has current projects focused on the human gut microbiome, on colorectal cancer, diabetes, xenobiotic metabolism, and 'missing microbes'. More recently Emma has entered the fascinating realm of the insect gut microbiome - specifically the microbes that colonize bees!
News of a slight bump in COVID-19 cases is raising concerns about new variants of the virus. The number of confirmed COVID-19 cases remains far below the low points seen earlier in the pandemic, but the uptick is a reminder that the virus, which killed over a million people in the U.S., continues to circulate. Andrew Pekosz is vice chair of the Department of Molecular Microbiology and Immunology at the Johns Hopkins Bloomberg School of Public Health. He joined us to talk about the emerging COVID-19 variants and the expected release of another round of vaccine boosters.

With the widespread presence of artificial sweeteners in the food system, scientists and consumers want to know about their safety. Safety concerns have been expressed for years, and lots of research has been done, but relatively new on the scene is work examining the effect of sweeteners on the microbiome. This interview is part of a series on the impact of artificial sweeteners. Our guest today, Dr. Jotham Suez, is doing fascinating work on this topic. He's Assistant Professor of Molecular Microbiology and Immunology and the Public Health Johns Hopkins University. Interview Summary So most everyone knows of the microbiome, but not everybody knows exactly what it is and how it works, so I'm hoping we might start with a quick overview of the microbiome. Could you help us with that? Sure, so I would say there are three really important things to know about the microbiome. We know that there are trillions of microbes, bacteria, and viruses living in our body. What everyone should know is that most of the systems in our body require these microbes for their proper development and proper function throughout our lifespan, so without these microbes, our immune system, and even our brain, would not develop properly, and if the microbiome is perturbed, this can lead to development of various diseases. That is the first thing. Already this implies that the microbiome is amenable to change, which is actually something that is attractive facet about the microbiome. If we know that the microbiome is involved in the pathogenesis of various diseases, then we can use that to our advantage, and we can think of way to change this microbial community to help protect us against disease, or even treat diseases in which the microbiome plays a role in the pathogenesis. The third thing that we should all think about is that the microbiome is some sort of a fingerprint. Each one of us has a unique microbial community in their body, and we can use that person-to-person difference in the microbiome on one hand, to predict disease risk. This is because some people would harbor the microbes that make them prone to diseases. We can also use that to tailor various drugs or various diets, or various therapeutics, to that community, because we would be able to say, based on your microbiome, how you would respond to a certain therapy or a certain diet. Heterogeneity in the microbiome plays an important role in personalized medicine. Thanks for helping establish how important the microbiome is, and also, how it can be affected in both positive and negative ways. So in that sense, what got you interested in the impact of artificial sweeteners on the microbiome? Yes. I think it was the person-to-person heterogeneity, and how that can lead to differential responses to diets or therapeutics. Just like you said, there have been decades of studies on efficacy of artificial sweeteners or potential safety concerns about whether they are helping us lose weight, helping us maintain healthy blood glucose levels, or they are actually doing the opposite. The studies are really all over the place. You would see studies that support a beneficial impact and studies that demonstrate detrimental impact. We were wondering as we started this research, if it's possible that this heterogeneity in outcomes of the studies is related to heterogeneity of the microbiome. Is it possible that some people are negatively impacted and some people are positively impacted, whether this is related to the differences in their microbiome. That's a fascinating area, and interesting to think that the same substance may have much different effects on people. So how have you gone about studying this yourself, and what have you found? We started very naively. I started when I was still a PhD student. I went to the supermarket, I purchased sachets of the most common artificial sweeteners that are out there, and we added that to the drinking water of mice. We saw that mice drinking these artificial sweeteners developed glucose intolerance, meaning they had poorer response to a simple sugar, which is how you would predict or diagnose pre-diabetes or diabetes in the clinic, for humans. We were able to show for the first time that sweeteners can actually cause negative impact on the metabolic health of an animal. What was more interesting is that we saw that these sweeteners also changed the microbiome of the mice drinking the sweeteners. What we've done then is take the microbiome of the animals that were drinking sweetener and we transplanted these microbes into mice that don't have any microbiome of their own. Just by giving them the microbes of mice that were drinking sweeteners, these mice also had a poorer metabolic response. We were able to show for the first time that the impact of sweeteners on the microbiome can result in a negative impact on our metabolic health. After a lot of experiments in mice, where we proved beyond any doubt that mice should not drink artificial sweeteners, we were really wondering what would be the impact on humans. We started a study in healthy individuals, so people that are not overweight and are without diabetes. We asked them to supplement their diet for two weeks with common artificial sweeteners, so sucralose, aspartame, saccharin, or one natural non-caloric sweetener stevia, and we followed up on glucose tolerance and also on their microbiome before, during, and after the exposure to the sweetener. We saw that two sweeteners, saccharine and sucralose, had a detrimental impact on their glucose tolerance. So just during two weeks of exposure to the sweetener, they had poorer responses to glucose. That would already put them on the path to potentially developing pre-diabetes and diabetes. We saw that all four sweeteners altered the microbiome. Again, when we took microbiomes of these people and transplanted them into germ-free mice we saw that the stronger the impact the sweetener had on your microbiome - that means that you would have a poorer metabolic response when you transplant these microbiomes into mice. This was really showing that there are person-to-person differences in the responses to sweeteners, and this depends on how much a microbiome is impacted by the sweetener. That was amazing summary in a short time of really complex and fascinating science. It's interesting that some sweeteners are having a stronger effect than others, which I guess makes more sense, because they're not all chemically alike. Is it possible to know when you get an effect on something like glucose tolerance from the use of the sweeteners, whether the microbiome is the main mechanism, the only mechanism? How does it fit in there when you start thinking about the impact of sweeteners on something like the glucose tolerance? That is a really great question, and I think the short answer would be that we don't know for sure. There have been multiple other groups that have been studying the impact of sweeteners on metabolic health or other parameters related to our health that have found fascinating mechanisms that are not related, or at least, not directly related to the microbiome. So for sure, sweeteners can have a broad impact on our body, not just for their impact on the microbiome, but what we are seeing, actually, is that's the impact that they have on the microbiome is sufficient to produce detrimental impact on metabolic health without any other measurable impacts, at least, in our studies. Many, many people have been using these artificial sweeteners in one form or another for many, many years, and in some cases, they're introduced into the food supply in ways that people may not even be aware of. Is there any way of knowing what happens if animals or humans have used these for a long period of time and they stop? Does whatever the impact on the microbiome reverse itself? That's a fascinating question. In the short term, that is something that we have measured in our studies, and others have done similar works in animal models. In a study like what we have done, which is two weeks of exposure, then one week of follow-up, you see some reversion of the microbiome to what it was before the exposure to the sweetener. But we should say that these individuals were recruited to the study precisely because they're habitually not drinking artificial sweeteners, so their body saw sweeteners potentially for the first time. So then if they immediately stopped after two weeks, in that scenario, we can say that the microbiome reverts. What happens after years of exposure to sweeteners, that's a study that we're definitely interested in doing, or I would be really happy to see the results if some is already doing such a study, but I am not aware of long-term studies where people just stopped taking sweeteners and then their microbiome was profiled. My mind is sort of firing with ideas of ways to study that question, but it's heartening to know that at least in the short term, at least some of the whatever damage is done starts to revert. That's very good news for people who have been using these products who choose to stop them for one reason or another, there may be a benefit to the microbiome. Let me ask about children. So many parents, they're concerned about the effect that the sweeteners might have on their children. Is anything known about this? Yes, I think this is a good point in the conversation to talk about the various types of evidence that we have about the detrimental impact of sweeteners. If we look at associative studies, most of these studies would find some sort of association between drinking artificial sweeteners and a negative impact on weight or on diabetes risk. So the associative studies are, for sure, pointing to a negative impact, but they don't provide evidence that the sweeteners are causing these negative impacts. So they might be a result of, you know, the changes in weight or the risk of diabetes rather than the cause. And then when you go to studies that actually provide causality, so these would be, for example, randomized controlled trials when you give the individual the sweetener then see what happens to their metabolic health, these types of studies are all over the place in terms of benefit versus risk, both in adults and in children. So unfortunately, there is no good answer to that question. There are studies that show a risk, but even studies that show a benefit. Even if there is risk from the artificial sweetener, some people may feel that the benefit, in terms of weight control, is more important, and they might say, "Well, I'm willing to accept the risk because of the benefit," but we've heard from others that whether these products actually help people control their weight is in question as well. What do you think about that topic? Yes, so what you would do when you have all of these studies that show even opposing results, and you try to find the truth, you would do a meta-analysis. When you perform meta-analysis on specifically the question of impact on weight, you find a very modest beneficial impact on weight. And even then, the quality of the evidence for that impact are low. Even if there is a benefit, it's very mild, and the evidence for such a benefit are not very strong. I think that's why organizations such as the World Health Organization have recently said that this may not be the best strategy for assisting individuals to lose weight. You mentioned that the two compounds that had the strongest effect on the microbiome were saccharin and sucralose. Is that correct? In our study, yes. So saccharin, I'm not sure how much that's used in the food supply still. It may be there, but it's been around forever. Maybe I'm wrong, but I figure that it's been displaced by lots of newer advances. But sucralose, which I think is marketed under the brand named Splenda, is a much more recent development in the field. It's interesting that that's having a negative effect too. So do you think that there's reason to believe that those two would be substances to avoid? I would say that you would never want to make public health decisions based on one study. I would say that that goes both ways, I think. I wouldn't advise avoiding saccharine just based on one study, and I wouldn't say that aspartame and stevia are safe just based on one study. I would say that others have found negative impacts for aspartame and for stevia that we have not seen very strongly in our study, whereas others have found both negative and neutral, or even beneficial effects for sucralose in other studies. So I would not make recommendations based on just our own study, but considering everything that is out there, I would say that all four sweeteners that we studied, and others, including Ace K, that we have not studied in a recent human study could pose a risk for some individuals. Unfortunately, right now, we don't have any good tools of predicting who would be those individuals, so it's a question of whether people should take that risk or not. Thank you for being appropriately cautious with the result, because as you said, the work is relatively recent, but why I'm really happy you're working on this topic. So summing this all up, what do you think is most important for people to know? I think, at this point in the research, and just recently, another group provided really interesting evidence about a different sugar substitute, erythritol, also posing a risk for cardiovascular disease, at this point in the research of artificial sweeteners and sugar substitutes, I think we cannot say that these substances are innocuous. They can pose a risk for at least some individuals, and we and others are definitely working hard on being able to help people know whether or not they are in those risk groups. But then the question is what can people do? I think what people should definitely not do is switch back to sugar. I think that if the evidence for the impact of artificial sweeteners are still something that requires further research. I think that the detrimental impacts of added caloric sugars in our diet, in our beverages, are beyond doubt linked to detrimental impacts on our metabolic health. So people should not switch back from diet soda to regular soda, that's for sure. But we and the industry alike should find ways of reducing the intake of sweeteners, and both caloric and non-caloric sweeteners in our diet to levels that hopefully don't pose as great a risk as what we are currently consuming. Bio Dr. Jotham Suez is a Feinstone Assistant Professor at the Johns Hopkins Bloomberg School of Public Health. Dr. Suez's work on non-nutritive sweeteners was instrumental in understanding how these popular food additives can counterintuitively disrupt glycemic control. During his graduate work at the Weizmann Institute, he demonstrated that sweeteners are not inert and can alter the gut microbiome, and causally linked those impacts to impaired glucose tolerance. He further showed that in humans, the microbiome mediates individualized responses to sweeteners, potentially underlying the conflicting literature on their impacts. Similarly, Dr. Suez's research on probiotics offers an opportunity to resolve the contradictory literature on their efficacy. His work highlighted the microbiome's importance in modulating probiotics colonization and downstream impacts. Inspired by these discoveries, Dr. Suez is fascinated by the potential of harnessing microbiome heterogeneity in precision medicine and personalized nutrition. In 2020, Dr. Suez received the NIH Director's Early Independence Award.

Antibiotics stopped providing big gains for pharmaceutical companies decades ago, but as bacteria become more resistant to drugs, the world needs new classes of antibiotics to be discovered if we want to prevent the next global health crisis. Dr Tina Joshi, Associate Professor of Molecular Microbiology at the University of Plymouth explains that it's more likely antimicrobial resistance will kill large numbers of human beings before climate change does. Kasim Kutay, CEO of the investment fund Novo Holdings tells us that for big pharma companies, antibiotics are seen as a contribution to society rather than an investment that can provide a profit. How can firms be convinced to invest in an unprofitable product? We hear how Netflix might provide a good model and we explore research in Phages - a bacteria specialised in eating other bacteria. Phages are being championed by some as a potential substitute for antibiotics. One patient in Minnesota tells us Phages saved his life.

Welcome to the latest episode of the podcast. This week I am talking to Alison Mowbray, former Olympic medal winning rower in the British Rowing Team, and current leadership development consultant and coach. Alison initially pursued an academic career in microbiology, got her PhD, became a science teacher… and then tried out for national selection in the British Rowing Team. She's competed at the Olympics twice and won silver as part of the quad sculls team in 2004. After retiring Alison continued to set and achieve her goals that included ultra-marathons, an autobiography, becoming a rowing coach, hiking, dancing tango, and more! Phewf! Join us to hear more about how Alison pursues her goals and what she has learnt about ikigai and her life's purpose along the way.If you enjoyed this episode and it inspired you in some way, we'd love to hear about it and know your biggest takeaway. In this episode you'll hear:How Alison pursued an academic path in Science, getting her PhD and becoming a science teacher before making the British Rowing Team at the age of 27How Alison decided what to do next after retiring from international rowingWhat marathon running taught Alison about how we can limit ourselves by the goals we setAbout the importance of doing things for yourself rather than always waiting for an external motivationAlison's advice on not judging what gives your life purpose, or comparing it to other people'sAbout Alison:Alison was on the British Rowing team for seven years and competed in five World Championships and two Olympic Games. Not being particularly sporty at school and having not even stepped in a boat until she went to Liverpool University at the age of 18, Alison then kept rowing on the back burner for many years while she pursued an academic career. Having achieved a 1st Class degree in Microbiology from Liverpool and a PhD in Molecular Microbiology from Cambridge University, Alison moved to London to train as a science teacher and attempt National selection. She made the British Rowing team that year at the age of 27. Two years later, she achieved last minute qualification for the Sydney 2000 Olympics, where she finished 10th in the single sculls event. Alison worked part-time as a science teacher while training full-time towards the Athens Olympics and in 2004, at the age of 33 and in the last race of her career achieved an Olympic silver medal in the final of the quad sculls. Retiring from international sport, Alison was a science teacher for several years alongside a developing career in Inspirational Speaking. She now works as a Leadership Development Consultant and Coach, hikes long-distance trails, runs marathons and ultra-marathons, dances tango and sings in a local choir. Alison also still coaches rowing, including to local children in Zambia in 2022.Alison wrote and published her autobiography: Gold Medal Flapjack.

Dr. Emma Allen-Vercoe, a foremost researcher on the human microbiome joins the Two Nobodys for a fascinating conversation. Emma shares what we do and do not know about the microbiome, some of the characteristics of a healthy microbiome, how it may have changed over history, the effects of COVID, and what foods may be beneficial. Dr. Emma Allen Vercoe's research page: https://www.uoguelph.ca/mcb/people/dr-emma-allen-vercoe Twitter: @EmmaAllenVercoe -- Dr. Emma Allen-Vercoe obtained her BSc (Hons) in Biochemistry from the University of London, and her PhD in Molecular Microbiology through an industrial partnership with Public Health England. Dr. Allen-Vercoe started her faculty career at the University of Calgary in 2005, with a Fellow-to-Faculty transition award through CAG/AstraZeneca and CIHR, to study the normal microbes of the human gut. In particular, she was among the few that focused on trying to culture these ‘unculturable' microbes in order to better understand their biology. To do this, she developed a model gut system to emulate the conditions of the human gut and allow communities of microbes to grow together, as they do naturally. Dr. Allen-Vercoe moved her lab to the University of Guelph in late 2007, and has been a recipient of several Canadian Foundation for Innovation Awards that has allowed her to develop her specialist anaerobic fermentation laboratory further. This has been recently boosted by the award of a Tier 1 Canada Research Chair in Human Gut Microbiome Function and Host Interactions . In 2013, Dr. Allen-Vercoe co-founded NuBiyota, a research spin-off company that aims to create therapeutic ecosystems as biologic drugs, on a commercial scale. The research enterprise for this company is also based in Guelph.

Two recent studies conducted at Oregon Health and Science University give some answers to questions about variants and vaccines. One study shows that people who have been infected with COVID-19, and therefore have natural immunity, are still vulnerable to new variants. And the Pfizer vaccine can help protect people with natural immunity against variants. At the same time, another study showed that the Pfizer vaccine is less effective at offering protection against variants in general than it is against the “wild-type” strain of the virus that originated the pandemic. This means people will probably have to get booster shots at some point. Marcel Curlin is an associate professor of medicine within OHSU's infectious disease division and co-senior author of both studies. He says the hope is that we can learn to live with the coronavirus in the same way we live with influenza. We hear from Curlin and co-senior author Fikadu Tafesse, who is also an assistant Professor of Molecular Microbiology and Immunology at the OHSU School of Medicine.
Ben is joined by Revive MD‘s Dr. Domenic Iacovone to discuss the Revive MD's present and future. Dr. Dom has a Bachelor's degree in Molecular Microbiology and went to Atlanta to get his Doctorate, completing his residency at the Synergy Sports Institute which is utilized by NFL players. With such a background, he's always trying to be innovative, and this episode shows just how much he's committing to that. Dr. Dom is extremely excited to announce Revive MD is now providing blood tests for free to those with insurance and heavily discounted for those without insurance The video and audio feeds are below, with more show notes after that: Video: Watch Dr. Domenic Iacovone Talk About Revive MD's Future https://www.youtube.com/watch?v=qYoFRlk0MG4 More than just a supplement brand, Revive MD is one of the only fully franchised medical facilities in the world, and every facility has an MD, a nurse practitioner, and a full-time nurse. They go where your standard primary care office is afraid to go, and where some are afraid to ask. For instance, they're not just a company providing hormones, they offer a myriad of additional services beside hormone replacement such as non-surgical facelifts, stem cell therapy, IV vitamin therapy, weight loss hormone replacement therapy, and more. Dr. Domenic explains that they staff physical therapists, and chiropractors. Big on peptide therapy However, Revive MD does not push hormones heavily, and is very big on peptide therapy. They're also very big on non-controlled substances to push the body to do what it's naturally supposed to do in the first place. Revive MD is research and science driven, but they work with athletes, and are coming hard at the “legal performance enhancement” side of the game. Will Wallace hired on As they're moving towards the future as an extremely unique company in the industry, Revive MD hired Will Wallace from Life Extension, who is worth his weight in gold. They continue to move very talented people to Florida, and Dr. Dom strives to ensure their entire business is built on education and intellectuals. Looking to the future, Dr. Dom wants to be better than a brick and mortar store, he wants to be a “Whole Foods” of his niche. He doesn't mind the brick and mortar model, but his vision for Revive MD is bigger than that. They are planning some very exciting things for the future and will release products to brick and mortar before they are released to the public. They also have a goal of supporting small businesses, which is critical in 2021. Additionally, Revive MD is working and collaborating with several professional athletes along with Will Wallace to bring out a big release that will be divulged at a later date. This was a phenomenal episode, and we can't wait to hear more from Dr. Iacovone and his partner at Revive MD and RAW Nutrition, elite bodybuilding coach Matt Jansen.

Hugo Rosen, MD is the Chair of Medicine and a Professor of Medicine, Immunology, and Molecular Microbiology at Keck School of Medicine of USC. Dr. Rosen completed his medical school from the University of Miami—Miller School of Medicine, his residency in internal medicine at Beth Israel Deaconess Medical Center at Harvard Medical School, followed by a fellowship in gastroenterology and transplant hepatology at UCLA. As a highly accomplished physician scientist, Dr. Rosen has more than 180 original peer reviewed manuscripts investigating the cellular and molecular underpinnings of a wide spectrum of innate and adaptive immune responses and developing novel paradigms in liver diseases. Dr. Rosen is an elected member of the American Society of Clinical Investigation and the American Association of Physicians, and currently serves as the deputy editor of the journal Hepatology. There is a formula for finding a great mentor: Talent x Accessibility. Today, Dr. Hugo Rosen explains that we should look for mentors who are not only talented in their field, but who are also accessible—and invested in you as the trainee. When one of these factors is diluted, it weakens the overall product. Dr. Rosen also reminds us that the lack of mentorship leads to missed opportunities. And it is up to us, as mentees, to not only seek out these relationships, but to prove that we are ones to invest in. “Think of it as an audition,” says Dr. Rosen. He explains that every interaction we have is a chance to display our work ethic, our willingness to learn, our humility—and the fire in our belly that drives us each day. Pearls of Wisdom: 1. Mentorship is not just about career development, it's about personal development. If a mentor is truly invested, the relationship becomes personal by default. 2. Finding a great mentor is about talent times accessibility. If the mentor is extremely talented but not accessible, the product will be zero. 3. Mentorship has to be driven by us, as the mentee. Show your mentor that you have vision and a fire in your belly, and use that to drive the interaction. 4. Every interaction is an audition.
Show Notes for Episode Fifteen of seX & whY: Sex Differences in Immunology and Drug Therapy Host: Jeannette Wolfe Guests: Evelyne Bischof MD, Associate Professor of Medicine at Shanghai University of Medicine and Health Sciences and internist at University Hospital of Basel Switzerland Sabra Klein, PhD, Professor of Molecular Microbiology and Immunology at Johns Hopkins Bloomberg School of Public Health This podcast focused on sex differences in immunology and pharmacology and its relevance to the Covid-19 pandemic. Key points Males are more likely to be admitted to the ICU and die from COVID-19 compared to females Males and females have differences in both innate and adaptive immunity (which likely are a combo of chromosomal, hormonal and epigentic differences) One difference in Innate immunity (the initial non-specific reaction to a foreign pathogen) is Toll-like receptor 7 (TLR7) This is a major player in the initial physiological response to a foreign pathogen and the gene for it is on the X chromosome. X-lined genes (like Ace-2 which is the receptor which SARS-Cov-2 initially binds to in the body) are interesting because they immediately bring up two considerations. First, if someone has a specific variant of that gene, it could change their susceptibility to certain pathogens. Males, as they have an XY pair of sex chromosomes, only have one X chromosome and thus could be more adversely impacted than females (XX) who have a second copy of the gene (which may or may not express the same variant) from their other X chromosome. The second consideration is that in the cells of most females, one of the X chromosomes is automatically turned off (X inactivation). It appears however, that some X-linked immune cells- like TLR7- don't do this, leading to the possibility of increased expression of the gene like getting an “extra dose”. In adaptive immunity (which involved B and T cells), females generally have a greater immunological response to most pathogens. As such, females generally exhibit a more robust immune response to natural infections and vaccinations. The flip side, however, is compared to men, women are also at greater risk for autoimmune diseases and are more likely to get local and systemic reactions after a vaccination. When testing the effectiveness and side effects of SARS-CoV-2 vaccines it would be ideal to consider the variables of biological sex and age. In an influenza study, when women were given a ½ dose of the flu vaccine, they mounted a similar immune response to males who got full dose. If the same held true for developing SARS-Cov2 vaccinations, it could potentially increase the amount of vaccine available (though it is unclear if this is even being considered in early vaccine trials). Aging can also impair the immune response and older adults may require higher doses of booster doses of some vaccines to optimize their immune response The use of Artificial Intelligence in drug development may revolutionize the pharmaceutical research industry by allowing more predictive drug modeling leading to more successful drug development. This could also be used to better identify potentially important biological sex- based pharmacodynamic and pharmacokinetic differences earlier in drug development. Two unexpected findings associated with COVID-19 Males appear to be more vulnerable to cytokine storm (mechanism still not entirely clear may be differences in ACE-2 receptors, or chromosomal/hormonal differences in innate/adaptive immune system) Elderly sick males who survived COVID-19 appear to have significant protective antibody production against SARS-Cov2 References: Bischof E, Wolfe J, Klein S: Clinical trials for Covid-19 should include Sex as a Variable.
