to test the possibility that insulitis might play an etiological role in the pathogenesis of insulin dependent diabetes , functions of 3 kinds of islet constituting cells ( a , b and pp cells ) were estimated by quantifying secretory responses of glucagon- , c-peptide-and pancreatic polypeptide-producing cells to hyperglycemia and hypoglycemia .
