Delta cells in the pancreatic islets secrete which hormone?

Explanation:
Delta cells provide local regulation in the pancreatic islets by secreting somatostatin, a hormone that inhibits the release of other hormones and slows gastrointestinal activity. This paracrine signal helps keep insulin and glucagon in balance, moderating their secretion to help maintain stable blood glucose levels. In the islets, alpha cells release glucagon to raise blood glucose, beta cells release insulin (and amylin) to lower it, and PP cells release pancreatic polypeptide. Since delta cells specifically produce somatostatin, that is the hormone described here.
