Abstract:Type 1 diabetes (T1D) is an autoimmune disease in which autoreactive T cells target and destroy islet β cells. The events that break peripheral tolerance in patients genetically predisposed to autoimmunity are poorly understood. Many physiological and environmental triggers associated with T1D cause endoplasmic reticulum (ER) stress, which may increase abnormal protein post-translational modification (PTM). We hypothesized that β cell ER stress generates neo-antigens that activate autoreactive T cells in T1D. … Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
