Fig. 7: Summary of findings.

Graphical abstract of findings showing that ablation of pancreatic beta-cell IL-22ra1 signaling leads to increased islet cellular stress and MHC II expression, reduced islet regeneration and insulin biosynthesis, and hypersecretion of proinsulin during glucose stimulation. These factors contribute to the age-related hyperglycaemia observed in IL-22ra1ΔβKO animals.
