Did you know that there are now over 80 different types of autoimmune diseases that impact multiple organs, tissues, cells and compounds such as enzymes in the body? An autoimmune disease occurs when your body's own immune system starts to attack itself, and as a result of this attack, it causes damage to the body leading to disease.Classifying different autoimmune diseases is no mean feat and requires scrutiny of your symptoms, biochemistry and whether the condition is organ-specific and systemic. And that is why many conditions that we don't class as autoimmune in nature could, in fact, have an element of autoimmunity. One such condition is polycystic ovarian syndrome (PCOS) which I repeatedly see in my clinical practice with my clients living with autoimmune diseases.

One of the challenges of T1D is identifying persons at high risk before the onset of clinical manifestations by screening for pancreatic β cell autoantibodies. Interventions to delay or prevent the underlying autoantibody-mediated loss of pancreatic β cells are now available to delay or potentially prevent the clinical presentation of T1D as diabetic ketoacidosis and mitigate subsequent, longer-term complications.=

Abstract: NMDA receptor autoimmune encephalitis (NMDAR-AE) is characterized by cerebrospinal fluid (CSF)-resident anti-NMDA receptor autoantibodies that cause behavioral and neurologic deficits. Although many symptoms are responsive to immunotherapy, for many patients functionally impairing deficits persist. We used patient-derived GluN1 and GluN2A-specific monoclonal antibodies (mAbs) to interrogate the molecular and circuit basis for persistent sensory-motor deficits following NMDAR-AE. During postnatal development, intracortical injection of either mAb disrupted callosal circuit formation with excess callosal projections in primary somatosensory cortex (S1), although the anti-GluN1 antibody provoked the more severe phenotype. S1 circuit disruption during development results in permanent axon morphology alterations and sensory-motor deficits lasting to adulthood. The severity of sensory-motor deficits was correlated with the severity of axon morphology alterations, and these anatomic changes are associated with sensory-motor behavior deficits similar to those in children NMDAR-AE. Our studies provide a molecular, cellular, and circuit basis for persistent neuropsychiatric deficits in NMDAR-AE. Copy rights belong to original authors.

There's a bit of a misunderstanding in the health world that endometriosis is just a hormone problem, but this line of thinking is incomplete. Hormones can absolutely contribute to the endometriosis picture, but they are not the cause of endometriosis. And part of treating endometriosis should include strategies to support the hormones, though that's not where the support should end. Today on the show Erin speaks with Dr. Lara Briden all about endometriosis and why it's such a complex thing to treat. Tune in to hear Lara dive into the immune side of endometriosis, epigenetics, gut dysbiosis, and how all these things can be interconnected. Erin and Lara also discuss testing options and strategies to treat endometriosis, plus and natural remedies you can try at home and lifestyle factors to consider. This episode is important to hear if you've been struggling with endometriosis or suspect you might have it, have been diagnosed with IBS but think there may be more going on, or if you're a practitioner looking to deepen your understanding on the complexities of endometriosis.

Distinguishing between type 1 and type 2 diabetes is critical, because delayed diagnosis of type 1 diabetes is associated with 20% or more risk of diabetic ketoacidosis, a major cause of death in children. Differentiating between type 1 and type 2 diabetes is also extremely important for choice of appropriate therapy. While the clinical presentation of a patient may not allow an unambiguous discrimination between type 1 and type 2 diabetes, the presence of one or more islet autoantibodies can support the diagnosis of type 1 diabetes, according to William Winter, MD, FCAP, the director of the UF Health Pathology Laboratories' Endocrinology Unit. Because islet autoantibodies can also predict the development of type 1 diabetes, once safe and effective therapies are available to prevent this disease, islet autoantibody testing will become routine in medical practice, as Dr. Winter explains in this CAPcast. Dr. Winter led the development of a Clinical Pathology Improvement Program or CPIP course on this topic.

Daiquiris and Dermatology

Pemphigus is an uncommon intraepidermal blistering disease occurring on the skin and mucous membranes. It is caused by autoantibodies to adhesion molecules expressed in the skin and mucous membranes. The cause is unknown. The bullae appear spontaneously and are tender and painful when they rupture. Drug induced pemphigus from penicillamine, captopril, and others have been reported. There are several forms of pemphigus: pemphigus vulgaris and its variant, pemphigus vegetans; and the more superficially blistering pemphigus foliaceus and its variant, pemphigus erythematosus. All forms may occur at any age, but most present in middle age. The foliaceus form is especially apt to be associated with other autoimmune diseases, or it may be drug induced. Paraneoplastic pemphigus, a unique form of the disorder, is associated with numerous types of benign and malignant neoplasms (typically non-Hodgkin lymphoma). Pemphigus is characterized by an insidious onset of flaccid bullae, crusts, and erosions in crops or waves. In pemphigus vulgaris, lesions often appear first on the oral mucous membranes. These quickly become erosive. The scalp is another site of early involvement. Practitioners can rub a cotton swab or finger laterally on the surface of uninvolved skin which may cause easy separation of the epidermis (this is Nikolsky's sign). The diagnosis is made with light microscopy and by direct and indirect immunofluorescence (IIF) microscopy. Autoantibodies to intercellular adhesion molecules can be detected with ELISA assays and have replaced the use of IIF in some centers. When the condition is severe, patients should be hospitalized at bed rest and given antibiotics/intravenous feedings. Anesthetic troches used before eating ease painful oral lesions. While pemphigus requires systemic therapy as early as possible, ironically, the main morbidity here is side effects from treatment. Initial therapy with systemic corticosteroids can consist of prednisone (60-80 mg daily). In most cases, a steroid sparing agent is added at the beginning at treatment (ex. azathioprine 100-200 mg daily, mycophenolate mofetil 1-1.5 twice daily). Treatment courses can be repeated in patients who do not achieve complete remission or relapse (ex. monthly IVIG at 2 g/kg intravenously over 3-4 days). In refractory cases, cyclophosphamide plus intravenous corticosteroids and plasmapheresis are also used. In patients who have a limited form of the disease, skin and mucous membrane lesions should be treated with topical corticosteroids. Complicating infection requires appropriate systemic and local antibiotic therapy. As far as complications are concerned, secondary infection can occur. This is a major cause of morbidity and mortality. Disturbances of fluid, electrolyte, and nutritional intake can occur as a result of painful oral ulcers. One in three patients will experience remission and, infection from S. aureus is the most frequent fatality cause. --- This episode is sponsored by · Anchor: The easiest way to make a podcast. https://anchor.fm/app

Abstract: Computer-aided rational vaccine design (RVD) and synthetic pharmacology are rapidly developing fields that leverage existing datasets for developing compounds of interest. Computational proteomics utilizes algorithms and models to probe proteins for functional prediction. A potentially strong target for such a computational approach is autoimmune antibodies which are the result of broken tolerance in the immune system where it cannot distinguish self from non-self resulting in attack of its own structures (proteins and DNA, mainly). The information on structure, function and pathogenicity of autoantibodies may assist in engineering RVD against autoimmune diseases. Current computational approaches exploit large datasets curated with extensive domain knowledge, most of which include the need for many computational resources and have been applied indirectly to problems of interest for DNA, RNA, and monomer protein binding. Here, we present a novel method for discovering potential binding sites. We employed long short-term memory (LSTM) models trained on FASTA primary sequences directly to predict protein binding in DNA-binding hydrolytic antibodies (abzymes). We also employed CNN models applied to the same dataset. While the CNN model outperformed the LSTM on the primary task of binding prediction, analysis of internal model representations of both models showed that the LSTM models highlighted sub-sequences that were more strongly correlated with sites known to be involved in binding. These results demonstrate that analysis of internal processes of recurrent neural network models may serve as a powerful tool for primary sequence analysis. Copy rights belong to original authors.

Between the latest online fads and the crazy media headlines, it’s easier than ever to get confused about your health. If you want to make better decisions about your health today so you can feel better and live longer, you’ve come to the right place. Today is the first episode of a three part series that examines the effect of grains on health. I’m joined today by the Gluten-Free Warrior — Dr. Peter Osborne, the founder of the Gluten-Free Society who works to help people with autoimmune and degenerative diseases. He shares some of the experiences and citations that have led him to work so passionately to educate people about the effect of grains on our overall health. Dr. Osborne has helped over 5,000 patients regain overall health and wellness with a grain-free diet, and his approach to healing is focused on individuals with auto-immune diseases.  If you’ve ever suspected that you might have gluten intolerance but aren’t sure if you have Celiac disease, if you’re wondering what environmental factors might be affecting your health, or if you are looking for ways to eliminate painful reactions to gluten, you need to listen to this conversation to help you decide which steps you need to take next.   Key Takeaways: [1:10] Today’s topic is grains — are they harmful to people who don’t have Celiac’s disease? [2:00] Introducing Dr. Peter Osborne, who shares his overall thoughts on the effects of grains on human health, the quality of studies that have been conducted about grains, and the importance of identifying autoimmune diseases when healing for chronic disease. [5:48] Dr. Osborne reacts to the statement that reduced-grain diets contribute to worse health outcomes, including cardiovascular death, and explains how the quality of the diet is a greater factor than the gluten intake itself. [9:52] The correlation between a grain-free diet and autoimmune disease, and a snapshot of the overall history and changing health factors that have an influence on a person's weakened health status. [15:00] The danger of not controlling for variables in a patient, the importance of believing that you can feel better again, and the value of overall body-fuel balance. [18:10] How can you tell if you have non-Celiac gluten sensitivity, and what can you do about it? Dr. Osborne suggests starting with diet change and supporting nutritional deficit. [22:30] Understanding the prevalence of non-Celiac gluten sensitivity and the environmental factors that accelerate it including exposure to pesticides, plastics, antibiotics, chemicals and medications. [27:04] Should all people with a gluten sensitivity be tested for Celiac’s disease?  Dr. Osborne says that it is not necessary, and he explains why. [29:40] What are the pitfalls of making dietary changes that are not accurate relative to the symptoms that are actually present? A look at the variables that affect overall health regardless of gluten-sensitivity. [37:04] If variables such as molds, pesticides and hybridization are present, it becomes increasingly difficult to separate individual aspects of the diet. Here’s what to do about it. [39:24] A list of conditions for non-Celiac gluten sensitivities that are actually caused by gluten and the next steps you should take to begin healing. [43:41] Dr. Osborne’s number one tip for enhancing overall health starts with self observation — pay attention to how your body responds to activity, exercise and food before you decide that your condition is irreversible.

Lupus isn’t well known, but the currently incurable autoimmune disease often marked by a ‘butterfly’ rash on the face, is highly prevalent, affecting five million people globally. Treatments are few and far between and few researchers are focused on it. But award winning medical researcher Professor Fabienne Mackay has concentrated much of her career on tackling lupus, and in 2011 her genetic research work led to the approval of the first new treatment for the disease in more than 50 years. And while that is good news for some patients, the treatment isn’t effective for all patients, and she says more research work and breakthroughs are needed. “I would love the public to realise that lupus is actually very prevalent; that the therapies we have at the moment, even though I worked towards one, are not serving everybody. It helps some patients but not all of them,” says Professor Mackay who in October 2019 received a Distinguished Innovator Award from the US-based Lupus Research Alliance. The good news is that we are still unravelling the secrets of the human body, which means there continues to be research leads to follow, including for instance the potential role of diet and the gut microbiome – the bacteria in our digestive system. “There is a whole story we didn’t realise was there and now it’s excitement all over again finding out how these layers are working on top of the layers we’ve already unravelled,” says Professor Mackay. “That is what fascinates me – you think you know it all and then there’s always something that comes and surprises you.” And her advice to her medical research students is to think big. “Always be bold. Think blue sky. It is a bit of risk and I know it’s never something that students are comfortable to do, but I think that where you find the most valuable discoveries.” Episode recorded: November 11, 2019.

If you are being treated for a blood disorder, it is time to look deeper and explore the underlying cause. Rather than simply addressing iron- or B12-deficiency anemia in isolation, ask WHY you have a deficiency in the first place. It is possible that damage to your intestines caused by gluten is preventing your body from absorbing the nutrients necessary to grow your red blood cells and keep your immune system healthy. And anemia is not the only blood disorder associated with celiac disease and non-celiac gluten sensitivity! The Gluten Free RN is taking a closer look at the hematologic manifestations of celiac disease from anemia to hyposplenism. She explains the connection between disorders of the blood and bones, offering insight around why men with both anemia and osteoporosis are also likely to have celiac disease. Nadine discusses the danger in taking H2 blockers or proton pump inhibitors for GERD long-term, describing how those medications decrease the gastric acid necessary for breaking down food. She also addresses what you can do to identify any nutritional deficiencies in your blood and reminds us why celiac patients have difficulty absorbing the nutrients necessary to form red blood cells.

Identification and temporal stability of conformational epitopes of autoantibodies against Myelin Oligodendrocyte Glycoprotein recognized by patients with different inflammatory central nervous system diseases

Myelin Oligodendrocyte Glycoprotein (MOG) is one of the few proteins known to be localized on the outermost sheath of central nervous system (CNS) myelin. Due to this localization, MOG is accessible to antibodies. Anti-MOG antibodies are demyelinating and enhance clinical symptoms in a number of animal models of CNS inflammation. Autoantibodies recognizing conformationally intact MOG are found in different inflammatory diseases of the CNS, but their antigenic epitopes had not been mapped. In this work, 9 variants of MOG with an intracellular enhanced green fluorescent protein (EGFP) tag were expressed on the cell surface of human HeLa cells and used to analyze sera from 111 patients (104 children, 7 adults), who had antibodies recognizing cell-bound human MOG. These patients had different diseases, namely acute disseminated encephalomyelitis (ADEM), one episode of transverse myelitis or optic neuritis, multiple sclerosis (MS), anti-aquaporin-4 (AQP4)–negative neuromyelitis optica (NMO), and chronic relapsing inflammatory optic neuritis (CRION). The expression levels of the mutants were comparable and cells with a defined expression level (fluorescence intensity in the EGFP channel of 102-103) were gated. Each MOG-mutant was recognized by at least one MOG-specific mAb. This allowed the comparison of binding to the different mutants. In order to assess the reproducibility of the system, binding of the 111 sera to the mutants was analyzed up to three times in independent experiments, yielding a very good reproducibility of the binding percentage with an absolute SD of 7.8% in the case of low recognition of a mutant and a relative SD of 20% in the case of high recognition of a mutant. The applied variants of MOG gave insight into epitope recognition of 98 patients. All epitopes identified in this work were located at loops connecting the ß-strands of MOG. The immunodominant epitope of human anti-MOG antibodies was at the membrane-proximal CC’-loop containing aa42, which is not present in rodent MOG. This loop was recognized by about half of all patients. Overall, seven epitope patterns were distinguished, including the one mainly recognized by mouse mAbs at the FG-loop around aa104. Evidence from mouse models of CNS inflammation shows that anti-MOG antibodies recognizing different epitopes can be demyelinating and thus pathogenic. This suggests that not only those antibodies recognizing the same epitope of MOG as the pathogenic mAbs (i.e. the FG-loop), but also the ones recognizing the CC'-loop are pathogenic in humans, as both epitopes allow for the recognition of cell-bound MOG. In half of the patients, the anti-MOG response was directed to a single epitope. To analyze the effect of glycosylation on the recognition of MOG by human autoantibodies, a “non-glycosylation mutant” N31D was made. Digestion with PNGaseF and Western blot analysis confirmed that N31 was the only used N-glycosylation site of the MOG constructs in HeLa cells. Glycosylation of MOG was not needed for antibody binding, but 8% of the patients recognized deglycosylated MOG at least two-fold better. The epitope specificity was not linked to certain disease entities. The individual epitope recognition patterns stayed constant in 11 analyzed patients over an observation period of up to 5 years without evidence for intramolecular epitope spreading. Some patients with acute syndromes had anti-MOG IgG at disease onset, but rapidly lost their anti-MOG IgG reactivity. These patients were able to generate a long-lasting IgG response to measles and rubella virus vaccine indicating that the loss of anti-MOG reactivity was not reflective of a lack of capacity for longstanding IgG responses. Human anti-MOG antibodies are mainly of the IgG1 isotype, which can activate complement and antibody dependent cellular cytotoxicity. Upon binding to MOG in the CNS, human anti-MOG antibodies are hence expected to cause demyelination. Transfer experiments with purified human anti-MOG antibodies have not been performed yet. The fact that the majority of human anti-MOG antibodies did not recognize rodent MOG has implications for animal studies. Using the described assay will help to identify patient samples appropriate for these transfer experiments and finally lead to the formal proof of the pathogenicity of human anti-MOG antibodies. This work also gives important information for future detection of potential mimotopes and the development of anti-MOG antibody detection assays and might pave the way to antigen-specific depletion.

B cells and antibodies constitute an important element in different inflammatory diseases of the central nervous system (CNS). Autoantibodies can serve as a biomarker to identify disease subgroups and may in addition contribute to the pathogenic process. One candidate autoantigen for multiple sclerosis (MS) is myelin oligodendrocyte glycoprotein (MOG). MOG is localized at the outermost surface of myelin in the CNS and has been the focus of extensive research for more than 30 years. Its role as an important autoantigen for T cells and as a target of demyelinating autoantibodies has been established in several variants of experimental autoimmune encephalomyelitis (EAE), an animal model of MS. The literature regarding antibodies to MOG in MS patients is confusing and contradictory. Recent studies, however, have described high levels of antibodies to conformationally correct MOG in pediatric acquired demyelination, both acute disseminated encephalomyelitis (ADEM) and MS. In adult MS, such antibodies are rarely found and then only at low levels. In this review, we summarize key findings from animal models and patient studies, discuss challenges in detecting anti-MOG antibodies in patients and present recent approaches to identifying new autoantigens in MS.

The occurrence of SOX2-specific autoantibodies seems to be associated with an improved prognosis in patients with monoclonal gammopathy of undetermined significance (MGUS). However, it is unclear if SOX2-specific antibodies also develop in established multiple myeloma (MM). Screening 1094 peripheral blood (PB) sera from 196 MM patients and 100 PB sera from healthy donors, we detected SOX2-specific autoantibodies in 7.7% and 2.0% of patients and donors, respectively. We identified SOX2211-230 as an immunodominant antibody-epitope within the full protein sequence. SOX2 antigen was expressed in most healthy tissues and its expression did not correlate with the number of BM-resident plasma cells. Accordingly, anti-SOX2 immunity was not related to SOX2 expression levels or tumor burden in the patients' BM. The only clinical factor predicting the development of anti-SOX2 immunity was application of allogeneic stem cell transplantation (alloSCT). Anti-SOX2 antibodies occurred more frequently in patients who had received alloSCT (n = 74). Moreover, most SOX2-seropositive patients had only developed antibodies after alloSCT. This finding indicates that alloSCT is able to break tolerance towards this commonly expressed antigen. The questions whether SOX2-specific autoantibodies merely represent an epiphenomenon, are related to graft-versus-host effects or participate in the immune control of myeloma needs to be answered in prospective studies.

Effects of the glutamic acid decarboxylase (GAD) inhibitor semicarbazide and anti-GAD autoantibodies-containing immunoglobulin G on neuronal network activity within the motor cortex

The electrical activity of the brain is the result of a complex interaction between excitation and inhibition mediated by several types of neurotransmitters. As the majority of neurons in the brain utilize either the inhibitory neurotransmitter γ-aminobutyric acid (GABA) or the excitatory neurotransmitter glutamate, the interplay of these two neurotransmitters principally controls brain excitability and, hence, imbalance between these two neurotransmitters may cause severe pathological conditions. Inhibition of glutamic acid decarboxylase (GAD), the rate-limiting enzyme of GABA synthesis, is believed to change neuronal network activity caused by impaired GABAergic inhibition. Recordings of intrinsic optical signals (IOSs) and whole-cell patch-clamp measurements of GABAA receptor-mediated miniature postsynaptic currents (GABAA Minis) and spontaneous excitatory postsynaptic currents (sEPSCs) were performed in the motor cortex in acute brain slices to unveil the effects of GAD inhibitors at the network level. The first project of this PhD thesis was to prove the IOS technique for its capability of monitoring neuronal network activity over several hours. Concurrently, new software for the analysis of IOS data was developed, which facilitates and significantly accelerates data analysis. Afterwards, changes in neuronal network activity after impairing GAD activity with the well-known GAD inhibitor semicarbazide (SMC) were observed with the IOS technique. If compared to the values of sham-drug application, a stable and reversible increase in both signal intensity and signal area was observed after 2 h of 2 mM SMC application. Consistent with these findings of IOS recordings, patch-clamp measurements of GABAA Minis revealed an SMC-induced reduction in the strength of GABAergic inhibition. The results are in line with the assumption that SMC impairs GABA synthesis by blocking GAD activity. SMC application, however, did not alter spontaneous excitatory neuronal network activity. The final aim of this study was to investigate potential effects of Anti-GAD autoantibodies-containing immunoglobulin G (IgG) derived from patients with stiff-person syndrome (SPS-IgG) on motor cortical neuronal network activity. IOS recordings do not reveal differences in neuronal network activity during SPS-IgG application and control IgG application. However, run-down of IOSs was significantly decelerated during IgG application, which possibly indicates a diminished neuronal cell death caused by an unspecific IgG effect. Compared to brain slices preincubated with IgG-free artificial cerebrospinal fluid, control IgG did not affect GABAA Mini amplitude and frequency as well as sEPSC amplitude. The sEPSC frequency, however, was significantly reduced under these conditions. This decreased excitatory transmitter release might explain the beneficial effect of immunoglobulin treatment in some forms of epilepsy. Similar to SMC, patch-clamp measurements of GABAA Minis revealed a reduction in the strength of GABAergic inhibition after preincubation with SPS-IgG. Consistent with this finding, application of SPS-IgG enhanced sEPSC frequency. This shows that IgG of SPS patients is indeed capable of altering GABAergic synaptic transmission, thus further supporting the hypothesis of an autoimmune origin of the stiff-person syndrome.

The aim of the present study was to investigate whether serologic markers of IBD, e. g. antibodies against Saccharomyces cerevisiae (ASCA), antibodies against exocrine pancreas (PAB) and perinuclear antineutrophil cytoplasmic antibodies (pANCA) are present in HLA-B27-associated SpA. Methods: 87 patients with HLA-B27-positive SpA and 145 controls were tested for ASCA, PAB and pANCA employing ELISA or indirect immunofluorescence, respectively. Antibody-positive patients were interviewed regarding IBD-related symptoms using a standardized questionnaire. Results/Conclusion: When compared to the controls, ASCA IgA but not ASCA IgG levels were significantly increased in patients with SpA, in particular in ankylosing spondylitis (AS) and undifferentiated SpA (uSpA). pANCA were found in increased frequency in patients with SpA whereas PAB were not detected. The existence of autoantibodies was not associated with gastrointestinal symptoms but sustains the presence of a pathophysiological link between bowel inflammation and SpA. Copyright (C) 2004 S.

A novel prokaryotic expression vector pGEX-6T was designed for high-level expression of recombinant fusion protein with a histidine-hexapeptide and glutathione-S-transferase at its N-terminus and the recombinant human preproinsulin at its C-terminus. Efficiency of expression was investigated in the Escherichia coli strain CAG456. The synthesized protein was sequestered in an insoluble form in inclusion bodies and was purified to homogeneity by one-step affinity chromatography based on the specific complex formation of the histidine-hexapeptide and a chelating matrix which was charged with Ni2+ ions. The antigenic nature of the purified recombinant preproinsulin fusion protein was evaluated by ELISA screening for insulin autoantibodies in selected sera from patients with recent-onset type 1 (insulin-dependent) diabetes mellitus classified by the existence of additional autoantibodies reactive against glutamic acid decarboxylase. 14% of the tested sera (n=43) conttained insulin autoantibodies which strongly recognized the recombinant human preproinsulin. Comparable measurements with both recombinant human preproinsulin and mature insulin suggested that the observed autoantigenicity of preproinsulin was mediated by the C-peptide or/and signal peptide.

The first human monoclonal islet cell antibodies of the IgG class (MICA 1-6) obtained from an individual with Type 1 (insulin-dependent) diabetes mellitus were cytoplasmic islet cell antibodies selected by the indirect immunofluorescence test on pancreas sections. Surprisingly, they all recognized the 64 kDa autoantigen glutamate decarboxylase. In this study we investigated which typical features of cytoplasmic islet cell antibodies are represented by these monoclonals. We show by double immunofluorescence testing that MICA 1-6 stain pancreatic beta cells which is in agreement with the beta-cell specific expression of glutamate decarboxylase. In contrast an islet-reactive IgM monoclonal antibody obtained from a pre-diabetic individual stained all islet cells but lacked the tissue specificity of MICA 1-6 and must therefore be considered as a polyreactive IgM-antibody. We further demonstrate that MICA 1-6 revealed typical features of epitope sensitivity to biochemical treatment of the target tissue which has been demonstrated for islet cell antibodies, and which has been used to argue for a lipid rather than a protein nature of target antigens. Our results provide direct evidence that the epitopes recognized by the MICA are destroyed by methanol/chloroform treatment but reveal a high stability to Pronase digestion compared to proinsulin epitopes. Conformational protein epitopes in glutamate decarboxylase therefore show a sensitivity to biochemical treatment of sections such as ganglioside epitopes. MICA 1-6 share typical features of islet cell and 64 kDa antibodies and reveal that glutamate decarboxylase-reactive islet cell antibodies represent a subgroup of islet cell antibodies present in islet cell antibody-positive sera.

We investigated the presence of autoantibodies to baculovirus-expressed human recombinant 65- and 67-kD isoforms of glutamate decarboxylase (GAD65 and GAD67) in insulin-dependent diabetes mellitus (IDDM). In the immunoprecipitation test using [35S]methionine-labeled GADs antibodies to GAD65 were detected in 13/15 (87%) islet cell antibody (ICA)-positive and in 1/35 (2.9%) ICA-negative first-degree relatives of patients with IDDM, in 6/11 (54.5%) ICA-positive nondiabetic schoolchildren, and in 35/50 (70%) patients with newly diagnosed IDDM. GAD67 antibodies were positive only in five (33%) of the ICA-positive relatives (P < 0.05) and in nine (18%) IDDM patients at onset (P < 0.00001). After onset of IDDM antibodies to GAD65 and GAD67 declined but were still positive in 25 and 9.4% of subjects with long-standing IDDM (> 10 yr). In all study groups antibodies to GAD67 were only detected in GAD65 antibody-positive sera. An immunotrapping enzyme activity assay for GAD65 antibodies was positive in 64/75 (85.3%) of sera that were GAD antibody positive in the immunoprecipitation test (r = 0.870, P < 0.0001). In two (2.7%) sera GAD65 antibodies that block GAD enzyme activity were found. Our data suggest that antibodies to GAD65 but not to GAD67 represent sensitive markers for preclinical and overt IDDM. The immunotrapping assay here described represents a valuable technique for specific and sensitive screening for GAD antibodies.

Out of a random population of 4208 non-diabetic pupils without a family history of Type I diabetes 44 (1.05%) individuals had islet cell antibody (ICA) levels greater or equal to 5 Juvenile Diabetes Foundation (JDF) units. 39 of these ICA-positives could be repeatedly tested for circulating insulin autoantibodies (CIAA) using a competitive radiobinding assay. The results were compared with the insulin responses in the intravenous glucose tolerance tests (IVGTT) and with HLA types. Six pupils were positive for CIAA. All of them had complement-fixing ICA, and 5 of them were HLA-DR4 positive. Three of the 6 showed a first-phase insulin response below the first percentile of normal controls. Our data indicate that in population-based studies CIAA can be considered as a high risk marker for impaired beta-cell function in non-diabetic ICA-positive individuals.
