Somatostatin, also known as growth hormone-inhibiting hormone (GHIH) or by several other names, is a peptide hormone that regulates the endocrine system and affects neurotransmission and cell proliferation via interaction with G protein-coupled somatostatin receptors and inhibition of the release of numerous secondary hormones. Somatostatin ...
In both species, the peptide hormone Urocortin III (Ucn3) is a major local signal that is released from beta cells (and alpha cells in primates) to induce the local secretion of somatostatin. [3] It has also been suggested that somatostatin may be implicated in insulin-induced hypoglycaemia through a mechanism involving SGLT-2 receptors.
It is a non-selective somatostatin receptor antagonist, [37] inhibiting the effects of somatostatin on target cells in the gastrointestinal tract, pancreas, hypothalamus, and central nervous system. [2] Cyclosomatostatin is used as a research chemical to investigate the effects of somatostatin on different cell types by antagonizing its ...
The main release-inhibiting hormones or inhibiting hormones are as follows: The hypothalamus uses somatostatin to tell the pituitary to inhibit somatotropin and to tell the gastrointestinal tract to inhibit various gastrointestinal hormones. There are various other inhibiting factors that also have tropic endocrine inhibition activity.
Cyclosomatostatin is one such compound. Contrary to previously discussed compounds, cyclosomatostatin does not contain a radionuclide. It is a non-selective somatostatin receptor antagonist, [36] inhibiting the effects of somatostatin on target cells in the gastrointestinal (GI) tract, pancreas, hypothalamus, and central nervous system (CNS).

Somatostatin: Pancreatic δ Cells: 1) Suppresses glucagon release from α cells (acts locally); 2) Suppresses release of Insulin, Pituitary tropic hormones, gastrin and secretin. 3) Decreases stomach acid production by preventing the release of other hormones (gastrin and histamine), thus slowing down the digestive process.

Beta cells are specialized cells in the pancreas that produce and release the hormone insulin, which helps regulate blood sugar levels. People with type 2 diabetes have a weakened beta-cell ...
Delta cells also release somatostatin which has been found to inhibit glucagon secretion. [5] Zinc is secreted at the same time as insulin by the beta cells in the pancreas. It has been proposed to act as a paracrine signal to inhibit glucagon secretion in alpha cells. Zinc is transported into both alpha and beta cells by the zinc transporter ...
