Abstract Upregulation of IL-17 immunity and detrimental effects on human islets have been implicated in type 1 diabetes. In animal models, the plasticity Th1/Th17 cells contributes to development autoimmune this study, we demonstrate that upregulation pathway peripheral blood are markers advanced β cell autoimmunity impaired function Activated Th17 was observed late stage preclinical diabetes children with glucose tolerance, but not early autoimmunity. We found an increased ratio IFN-γ/IL-17...
