Somatostatin (SST) is a peptide hormone, which can regulate the endocrine system. Specifically, Somatostatin affects neurotransmission and cell proliferation by interacting with G protein-coupled somatostatin receptors and inhibiting multiple releases. Besides, Somatostatin inhibits insulin and glucagon secretion. Moreover, Somatostatin is produced by neuroendocrine neurons in the hypothalamic extraperitoneal nucleus....
