Researchers at the University of Cincinnati have discovered a therapy that reverses new onset Type 1 diabetes in mouse models. The treatment targets the innate immune system and boosts activity of TLR4, preserving insulin-producing beta cells. This approach may hold promise for treating Type 1 diabetes in humans.
Researchers found that CVID patients with a single altered TACI allele maintain some residual B cell responsiveness, promoting autoantibody development. In contrast, individuals with two mutated copies of TACI have complete impairment of B cell responses, likely preventing autoimmunity.
Researchers have identified plasmacytoid dendritic cells (pDCs) as a key producer of type I interferons in lupus, which can be targeted to prevent autoimmunity. Blocking this pathway may offer a potent weapon against the disease.
Researchers have identified a genetic variant associated with an increased risk of autoimmune diseases like type 1 diabetes. In a mouse model study, turning off the PTPN22 gene reduced the risk of autoimmune diabetes and increased regulatory T cells.
Researchers at Duke University Medical Center have discovered a rare type of B cell that regulates immune responses and limits autoimmunity. By infusing these cells into mice with autoimmune disease, symptoms were significantly reduced. Further research is needed to expand human B10 cells and determine their behavior in humans.
Researchers at Benaroya Research Institute will receive $4.7 million in grants to study immune function and develop new therapies for autoimmunity prevention. The goals include understanding how the immune system becomes unbalanced in individuals with autoimmune diseases.
Researchers found that infection with gammaherpesvirus 68 significantly reduces lupus symptoms in mice, including decreased antibodies, reduced tissue damage, and inhibited activation of lymphocytes and dendritic cells. The study suggests a possible mechanism for how the virus protects against autoimmunity.
Scientists discover a possible therapy for hereditary sensory and autonomic neuropathy type 1, reversing toxic molecule accumulation in mice. Additionally, researchers design minihepcidins to reduce iron overload by mimicking the natural protein's ability to lower blood iron levels.
The University of Maryland School of Medicine will establish a research enterprise dedicated to autoimmune and inflammatory diseases, including celiac disease. The $45 million gift from Ken and Shelia Cafferty will support multidisciplinary research and collaborations with the University of Maryland Institute for Genome Sciences.
Researchers propose a new theory on the cause of autoimmunity in diabetes, suggesting that unusual protein fragments can trigger an immune response. This discovery could lead to a new strategy for preventing type 1 diabetes.
Hilde Cheroutre's groundbreaking proposal aims to pinpoint molecular events underlying autoimmunity susceptibility, enabling early detection and potentially preventing the disease. Her innovative approach could also lead to new therapies for those at high risk or already affected by autoimmunity.
A study found that the Gpx5 protein helps protect immature mouse sperm from oxidative stress, which is associated with fertility issues and miscarriages. In contrast, high levels of IL-21 are linked to an increased risk of developing autoimmune diseases in multiple sclerosis patients treated with alemtuzumab.
The JDRF Scholar Award is granted to individual scientists who exhibit a unique creative vision and approach to research. Dr. Jeffrey Bluestone and Dr. Mark Cooper are the recipients of this prestigious award, which provides them with $250,000 annually for up to five years to conduct specialized research.
The JDRF Autoimmunity Center will focus on developing novel antigen-specific approaches to predict, prevent, and possibly reverse type 1 diabetes. The center will utilize the Barbara Davis Center's resources in collaboration with JDRF to create therapies specifically aimed at immunoprevention of type 1 diabetes.
Researchers found that WASP protein is crucial for regulatory T cells to regulate autoimmunity and prevent tissue damage. In humans, a population of T cells known as regulatory T cells (Treg) are impaired without WASp, leading to autoimmune disease.
Researchers found that Omenn syndrome patients have greatly reduced autoimmune regulator (AIRE) expression in their thymuses, which leads to a lack of central tolerance. This results in the survival of autoreactive T cells, causing increased autoimmunity risk.
Researchers found that patients with autoimmune disease have higher levels of fatty deposits in blood vessels, which cause heart disease. Additionally, atherosclerosis worsens autoimmune symptoms, implying that low-fat diets may benefit patients with autoimmune disease.
A new hypothesis suggests that autoimmunity is triggered by insufficient immune stimulation, leading to a decrease in T cells and an overactive expansion of the remaining population. This condition, known as lymphopenia, can cause diseases like Type 1 diabetes and rheumatoid arthritis.
Sick Kids researchers discovered that nervous system autoimmunity attacks insulin-producing cells in the earliest stages of Type 1 diabetes. By modifying the attack on nervous tissue, they prevented subsequent diabetes in animal models, suggesting a critical role for early neuronal autoimmunity.
Researchers found leptin significantly correlates with reduction in food intake and weight loss prior to developing EAE symptoms. Modulating leptin concentration through dietary approaches may have potential utility in treating MS and other autoimmune diseases.
Researchers have discovered abnormal immune regulation and autoimmunity in children with a form of autism characterized by sudden regression. The study reveals distinct autoimmune features in the epithelium of the small bowel, which may contribute to bowel symptoms and cognitive regression in autistic children.
