Diabetic patients show elevated plasma IL18 concentrations. IL18 has two receptors: IL18 receptor (IL18r) and the Na-Cl co-transporter (NCC). Here we report that IL18 is expressed on islet α cells, NCC on β cells, and IL18r on acinar cells in human and mouse pancreas. Deficiency of these receptors reduces islet size, β-cell proliferation, and insulin secretion, but increases β-cell apoptosis and exocrine macrophage accumulation after diet-induced glucose intolerance or streptozotocin-induced hyperglycemia. Together with the GLP1 (glucagon-like peptide-1), IL18 uses NCC and GLP1 receptor on β cells to trigger β-cell development and insulin secretion. IL18 also uses IL18r on acinar cells to block hyperglycemic pancreas macrophage expansion. β-cell-selective depletion of NCC or acinar cell-selective IL18r depletion reduces glucose tolerance and insulin sensitivity with impaired β-cell proliferation, enhanced β-cell apoptosis and macrophage expansion and inflammation in mouse hyperglycemic pancreas. IL18 uses NCC, GLP1r, and IL18r to maintain islet β-cell function and homeostasis. Zhang et al. demonstrate that IL18 and GLP1 bind to both Na-Cl co-transporter and GLP1 receptors on islet β cells, controlling β-cell apoptosis, proliferation, and insulin secretion. IL18 activates acinar cells via the IL18 receptor, regulating hyperglycemic exocrine and endocrine inflammation and islet β-cell function and homeostasis.
