Which cells are known for secreting somatostatin?

Delta cells are responsible for the secretion of somatostatin, a hormone that plays a critical role in regulating the endocrine system and inhibiting the release of several other hormones. Specifically, somatostatin inhibits the secretion of both insulin and glucagon, which are produced by beta and alpha cells, respectively. By regulating these hormones, somatostatin helps maintain glucose homeostasis and contributes to the overall balance of metabolic processes in the body.

The delta cells are located within the islets of Langerhans in the pancreas, highlighting their importance in coordinating the functions of various pancreatic cells. In this context, recognizing the role of delta cells is essential for understanding how the body manages metabolic regulation, particularly concerning insulin and glucose levels.
