The Gastrin-ECL Cell Axis. Functional Aspects

increase secretion of somatostatin ECL cells synthesize and secrete histamine.These cells are stimulated by the hormones gastrin (not depicted in the adjacent diagram) and pituitary adenylyl cyclase-activating peptide.G cells are stimulated by vagal stimulation through the neurotransmitter gastrin-releasing peptide; this causes the G cells to secrete gastrin, which in turn stimulates ECL cells to release histamine.

Do ECL cells in the rat oxyntic mucosa secrete a calciotropic hormone? @article{1996DoEC, title={Do ECL cells in the rat oxyntic mucosa secrete a calciotropic hormone?}, author={}, journal={Regulatory Peptides}, year={1996}, volume={64} } In the oxyntic mucosa of the mammalian stomach, histamine is stored in enterochromaffin-like (ECL) cells and in mucosal mast cells. The activity of the histamine-forming enzyme, histidine decarboxylase (HDC), is high in ECL cells but lower in the mucosal mast cells.

Choline esters and Enterochromaffin cell-like (ECL) hyperplasia is a benign, but potentially pre-neoplastic condition associated with hypergastrinemic states. Hypergastrinemia may be induced by: potent inhibitors of acid secretion (H2-blockers or proton pump inhibitors omeprazole, lansoprazole, pantoprazole); When stimulated, parietal cells secrete HCl at a concentration of roughly 160 mM (equivalent to a pH of 0.8). The acid is secreted into large cannaliculi, deep invaginations of the plasma membrane which are continuous with the lumen of the stomach. ECL-cell (fysiologi) enskild cell av en typ av celler som finns i magsäckens slemhinna och producerar histamin som en del i regleringen av saltsyrasekretionen G-cellerna producerar gastrin som får ECL-cellerna att frisätta histamin, som i sin tur får parietalcellerna att producera saltsyra.

Both areas include surface mucosa cells, colon mucosa cells, and enterochromaffin cells, as well as D cells, which secrete somatostatin 11, 14, 19, 24. Regulation of gastric acid secretion is achieved through an interaction between the two main gastric endocrine cells, the G cells and the D cells. In this study, fundamental electroopticalcharacteristics of ECL cells were evaluated in order to apply the ECL phenomena to light emitting devices ordisplay devices.

Prior to the recognition of the ECL cell as the pivotal regulator of gastric acid secretion, there was considerable confusion in regard to the mechanism by which the parietal cell was stimulated to secrete acid. The identification of the ECL cell and the recognition of its primary secretory product, histamine, dispelled the previous notion that The enterochromaffin-like (ECL) cells of the oxyntic mucosa (fundus) of the stomach produce, store and secrete histamine, chromogranin A-derived peptides such as pancreastatin, and an unanticipated but as yet unidentified peptide hormone. The cells are stimulated by gastrin and pituitary adenylate cyclase activating peptide and suppressed by somatostatin and galanin. Somatostatin, misoprostol and galanin inhibit gastrin- and PACAP-stimulated secretion of histamine and pancreastatin from ECL cells by blocking specific Ca(2+) channels.

Gastric acid secretion is under nervous and hormonal control. Gastrin, the major circulating stimulus of acid secretion, probably does not stimulate the parietal cells directly but acts to mobilize histamine from the ECL cells in the oxyntic mucosa. Histamine stimulates the parietal cells to secrete HCl. Histamine in the stomach occurs in endocrine cells (so-called enterochromaffin-like (ECL) cells), mast cells, and neurons. The ECL cells are peptide hormone-producing cells.

Four different types of cells make up the gastric glands: The endocrine cells secrete the hormone gastrin, which functions in the regulation of gastric activity.
