Gastrin is transferred from a specific type of G cell in the gastric epithelium to the ECL cells by blood. Histamine and gastrin act synergistically as the most important stimulators of hydrochloric acid secretion from parietal cells and stimulators of secretion of pepsinogen from chief cells .

Gastrin from G cells in the antrum is the main stimulus of gastric acid secretion. Gastrin stimulates the ECL cells in the oxyntic mucosa to mobilize histamine, which in turn stimulates the parietal cells to produce hydrochloric acid. Interestingly, gastrin stimulation also increased ECL cells expression of anti-apoptotic genes. Conclusion: The ECL cell specific expression profile is reminiscent of that of neurons and other endocrine cells exhibiting high expression of genes encoding proteins involved in the synthesis, storage and secretion of neuropeptides or peptide hormones. Enterochromaffin-like (ECL) cell function in transgenic mice expressing gastrin in pancreatic β-cells AIM: Gastrin stimulates acid secretion by mobilizing histamine from enterochromaffin-like (ECL) cells that occur predominantly at the base of the gastric glands.

Inhibition is achieved Achlorhydria induces G cell hyperplasia and overproduction of gastrin from G cells Increased gastrin stimulates ECL cell hyperplasia in the gastric body (predisposing to well differentiated, type I neuroendocrine tumors) (Clin J Gastroenterol 2019 Nov 28 [Epub ahead of print]) Enterochromaffin-like (ECL) cells, in contrast to EC cells, are confined to a single region of the gut, the gastric fundus, where they form the major endocrine cell population. ECL cells have no lumenal connection (Fig. 6). The cells are argyrophil but nonargentaffin. The ECL cells constitute the major endocrine cell population in the acid-producing part of the stomach. Gastrin from G cells in the antrum is the main stimulus of gastric acid secretion.

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.

Conclusion: The ECL cell specific expression profile is reminiscent of that of neurons and other endocrine cells exhibiting high expression of genes encoding proteins involved in the synthesis, storage and secretion of neuropeptides or peptide hormones.

That this sequence of events occurs not only with omeprazole but also with other effective gastric antisecretory agents has been verified in the rat by giving the H 2 -receptor antagonist ranitidine as a continuous infusion. AIM: Gastrin stimulates acid secretion by mobilizing histamine from enterochromaffin-like (ECL) cells that occur predominantly at the base of the gastric glands.

An increased number of ECL cells possibly related to the increased serum gastrin levels, have been observed in some patients during long-term treatment with

The gastrin-ECL cell pathway has been investigated extensively in situ (gastric submucosal microdialysis), in vitro (isolated ECL cells) and in vivo (intact animals). In gastric enterochromaffin-like (ECL) cells, stimulation with gastrin leads to a prompt biphasic calcium response followed by histamine secretion. This study investigates the underlying signaling events in this neuroendocrine cell type. In ECL cells, RT-PCR suggested the presence of inositol 1,4,5-trisphosphate receptor (IP (3)R) subtypes 1-3. Enterochromaffin-like or ECL cells are a distinctive type of neuroendocrine cell in the gastric mucosa underlying the epithelium. They are most prevalent in the acid-secreting regions of the stomach. ECL cells synthesize and secrete histaminein response to stimulation by the hormones gastrinand pituitary adenylyl cyclase-activating peptide.

We are therefore faced with the paradox of an effec-tive in vitro stimulant of gastric ECL cell function acting as an inhibitor of acid secretion in vivo (18, 19). The studies discussed here show that PACAP is an effec-tive ligand on PAC1 of isolated ECL cells (and of ECL cells Since gastrin‐evoked histamine mobilization from isolated ECL cells was dose‐dependently inhibited by the anaesthetic agents used in this study (except urethane), we propose that the suppressive effect is exerted directly on the ECL cell. ECL cells were identified by posi- tion, size, and autofluorescence and parietal cells by position and size. Results: Gastrin (1 pmol/L) produced an elevation of [Ca]~ levels in both ECL and parietal cells. In the presence of 100 pmol/L cimetidine, the EOL cell response to gastrin was not affected but the ECL CELL PROLIFERATION AND GASTRIN. LEVELS. Dear Sir: In 1969, Rubin 1 pointed out that a proliferation of endocrine cells does occur in atrophic In contrast to the other two major gastric secretagogues, acetylcholine and histamine, gastrin only weakly stimulates the acid secretion in isolated parietal cells At similar gastrin levels, ECL-cell hyperplasia of the same magnitude developed during both ranitidine and omeprazole treatment.
