Somatostatin is secreted by delta cells at several locations in the digestive system, namely the pyloric antrum, the duodenum and the pancreatic islets. [14]Somatostatin released in the pyloric antrum travels via the portal venous system to the heart, then enters the systemic circulation to reach the locations where it will exert its inhibitory effects.
The δ-cells in the stomach contain CCKBR (which respond to gastrin) and M3 receptors (which respond to Ach). Respectively, these receptors will increase somatostatin output and decrease somatostatin output from the δ-cells. VIP, vasoactive intestinal peptide, acts positively on δ-cells resulting in more somatostatin being released.
Somatomedin C, Human. Somatomedins are a group of proteins produced predominantly by the liver when growth hormones act on target tissue. Somatomedins inhibit the release of growth hormones by acting directly on anterior pituitary and by stimulating the secretion of somatostatin from the hypothalamus.
Brockmann body is an endocrine organ in some teleost fish, and is composed of a collection of islet tissues. The islet tissues are in turn composed of endocrine cells which are the principal sites of insulin synthesis. [1] They are distributed around the spleen and the large intestine. They also secrete other hormones such as glucagon and ...
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. Lowers [citation needed]
It is a key mediator of anabolic activities in numerous tissues and cells, such as growth hormone-stimulated growth, metabolism and protein translation. [17] Due to its participation in the GH-IGF-1 axis it contributes among other things to the maintenance of muscle strength, muscle mass, development of the skeleton and is a key factor in brain ...
Neuroendocrince cells of the Periventricular nucleus in hypothalamus: Somatostatin receptor: Inhibit release of GH and TRH from anterior pituitary Suppress release of gastrin, cholecystokinin (CCK), secretin, motilin, vasoactive intestinal peptide (VIP), gastric inhibitory polypeptide (GIP), enteroglucagon in gastrointestinal system
A type of cell in the pancreas clumped with other cells (in the islets of Langerhans). Delta cells make somatostatin, a hormone that is believed to control how the beta cells make and release insulin and how the alpha cells make and release glucagon. Desensitization A method to reduce or stop an allergic reaction to something.
