GENERAL HISTOLOGY

Detailed explanation-1: -Pancreatic polypeptide cells (PP cells), or formerly as gamma cells (-cells), or F cells, are cells in the pancreatic islets (Islets of Langerhans) of the pancreas. Their main role is to help synthesize and regulate the release of pancreatic polypeptide (PP), after which they have been named.

Detailed explanation-2: -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.

Detailed explanation-3: -A pancreatic cell that produces hormones (e.g., insulin and glucagon) that are secreted into the bloodstream. These hormones help control the level of glucose (sugar) in the blood.

Detailed explanation-4: -The islets of Langerhans contain four cell types that each secrete a different peptide: alpha cells secrete glucagon, beta cells secrete insulin, delta cells secrete somatostatin, and P (F) cells secrete pancreatic polypeptide.
