Beta cell dysfunction occurs independently of insulitis in type 1 diabetes pathogenesis
27 Aug 2025
Abstract excerpt
The loss of insulin secretory function associated with type 1 diabetes (T1D) is attributed to the immune-mediated destruction of beta cells. Yet, at onset of T1D, patients often retain a substantial beta cell mass, and T cell infiltration of pancreatic islets is typically sporadic. Here, we investigate the hypothesis that the remaining beta cells in T1D are dysfunctional, using live pancreas slices from organ...
