背景
Pancreatic poLypeptide prohormone,PH,Pancreatic poLypeptide Y,Pancreatic poLypeptide,Pancreatic icosapeptide,PPY,PNP,Pancreatic polypeptide (PP),36-amino acid peptide,may function as an important feedback inhibitor of pancreatic secretion after a meal. It arises from both islet and acinar cells of the pancreas. Release of PP by a meal,primarily protein,occurs in a biphasic manner. PP is a negative regulator of energy homeostasis that suppresses food intake and lowers body weight. Similar to other gastrointestinal-derived peptides,PP also modulates gastrointestinal motility and may be involved in the regulation of anxiety. PP,a robust anorexigenic hormone,effectively modulates food intake and energy homeostasis,thus potentially aiding anti-obesity therapeutics. PP is produced in pancreatic islets of Langerhans and released into the circulation after ingestion of a meal. Peripherally administered PP suppresses food intake and gastric emptying. On the other hand,central administration of PP elicits food intake and gastric emptying.
