Concept and therapeutic applications: the endocrine pancreas

The endocrine pancreas is the part of the pancreas that makes and distributes hormones directly into the bloodstream. The organ known as the pancreatic islets, called initially islets of Langerhans, comprises a group of cells. The endocrine pancreas produces four hormones: insulin, glucagon, somatostatin, and pancreatic polypeptide (PP). The two primary hormones controlling blood sugar levels are insulin and glucagon. Blood sugar levels are lowered as insulin encourages the body’s cells to absorb glucose from the blood. Glucagon stimulates the liver to release glucose and increases blood glucose levels. Glucagon and insulin are inhibited by somatostatin, which keeps blood sugar levels within a healthy range. PP are believed to 242play a role in regulating digestion and appetite. A significant portion of the therapeutic applications involving the endocrine pancreas are related to managing diabetes mellitus and related conditions. These applications include insulin replacement therapy, glucagon administration, artificial pancreas, pancreatic islet transplantation, glucose monitoring, somatostatin analogs, pancreatic hormone replacement therapy, and many more. Medical research and technological advancements continuously advance therapeutic approaches involving the endocrine pancreas.
