Image Caption Two harmless peptides are fused to activate high affinity T cells in Type 1 diabetes.
Description More than 1 million Americans suffer from Type 1 diabetes, which occurs when immune T cells attack the patient's own pancreas by mistake. Understanding why this occurs is key to developing treatments that target the cause, not just the symptoms of diabetes. Recent advances by Bettini, Evavold, Liu and colleagues have shown that specific fusions/modifications between insulin and other proteins creates new immunological targets that allow pathogenic high affinity T cells to escape tolerance, destroy pancreatic beta cells and initiate Type 1 diabetes.
