What Types of Cells are Found in the Islets of Langerhans?
The Islets of Langerhans contain several types of hormone-producing cells, each with distinct functions:
Alpha Cells: These cells produce glucagon, which raises blood glucose levels by stimulating the liver to convert glycogen into glucose. Beta Cells: Responsible for producing insulin, which lowers blood glucose levels by facilitating the uptake of glucose into cells. Delta Cells: These cells secrete somatostatin, a hormone that inhibits the release of both glucagon and insulin. PP Cells (or F Cells): These cells produce pancreatic polypeptide, which regulates both the exocrine and endocrine functions of the pancreas. Epsilon Cells: These cells secrete ghrelin, a hormone that stimulates appetite.
