In type 1 diabetes, a lifelong autoimmune disease, T cells infiltrate the islets and the exocrine pancreas in high numbers. CD8+ T cells are the main cell type found in the insulitic lesion, and CD8+ T cells reactive against beta cell antigens have been detected in the periphery and in the pancreas of subjects with short and long disease duration. The Diabetes Virus Detection (DiViD) study collected pancreatic tissue, by pancreatic tail resection, from living patients with recent-onset type 1 diabetes. These tissues have been extensively studied by the scientific community, but the autoreactive nature of the T cell infiltrate has remained unexplored. Our objective was to determine the number and localization of these cells in pancreas samples obtained through the DiViD study. Here, we demonstrate the presence of high frequencies of CD8+ T cells reactive against a highly relevant epitope derived from the preproinsulin signal peptide in pancreatic tissue samples from these donors. We additionally show the heterogeneity of islet distribution and CD8+ T cell infiltration. Our findings contribute to the current limited existing knowledge on T cell reactivity in the pancreas of recent onset type 1 diabetic donors, and indicate that antigen-specific therapies directed towards preproinsulin could have high clinical impact.

Cytotoxic CD8 T lymphocytes play a central role in the tissue destruction of many autoimmune disorders. In type 1 diabetes (T1D), insulin and its precursor preproinsulin are major self-antigens targeted by T cells. We comprehensively examined preproinsulin specificity of CD8 T cells obtained from pancreatic islets of organ donors with and without T1D and identified epitopes throughout the entire preproinsulin protein and defective ribosomal products derived from preproinsulin messenger RNA. The frequency of preproinsulin-reactive T cells was significantly higher in T1D donors than nondiabetic donors and also differed by individual T1D donor, ranging from 3 to over 40%, with higher frequencies in T1D organ donors with HLA-A*02:01. Only T cells reactive to preproinsulin-related peptides isolated from T1D donors demonstrated potent autoreactivity. Reactivity to similar regions of preproinsulin was also observed in peripheral blood of a separate cohort of new-onset T1D patients. These findings have important implications for designing antigen-specific immunotherapies and identifying individuals that may benefit from such interventions.
