In mammals they are located basally in the oxyntic gland area, in the chief-cell-rich region. Parietal cells predominate in t he mid-region. “Enterochromaffin-like (ECL) cells” are a population of cells that are found in the gastric pits of the stomach luminal epithelium and secrete histamine. In response to gastrin released by neighbouring G-cells, secreted histamine from ECL cells acts on parietal cells to stimulate the release of gastric acid.
ECL cells secrete histamine when stimulated either by the autonomic nervous system or by gastrin. and mechanism of histamine release from the ECL cell in the peripheral regulation of acid secretion, usingpuri- fied ECL cells from rat fundic mucosa. Methods: Background & Aims: Gastrin stimulation of the type 2 cholecystokinin (CCK2) receptor results in ECL cell proliferation and histamine secretion. This report Abstract Enterochromaffin-like (ECL) cells are neuroendocrine cells in the gastric mucosa that control acid secretion by releasing histamine as a paracrine ECL cells respond to food intake or vagal nerve stimulation by releasing histamine (8), but the number of these cells is insignificant in the antral stomach. Finally, Feb 16, 2016 The gastrin (from G-cells) stimulates the ECL cells to produce and secrete histamine while, in a reciprocal way, this histamine (from ECL cells), The histamine-storing ECL cells in the stomach play a key role in the control of acid secretion.

Histamine and chromogranin A-derived peptides in rat
Chormogranin A (CgA)-derived peptides, such as pancreastatin, are co-secreted with histamine. Aim: Gastrin stimulates acid secretion by mobilizing histamine from enterochromaffin‐like (ECL) cells that occur predominantly at the base of the gastric glands. The parietal cells occur higher up in the glands nearer to the gastric lumen.

Cholecystokinin 2016-09-26 Histamine, released from ECL cells, is the most impor-tant direct stimulant of acid secretion, as shown by the broad efficacy of histamine-2 receptor antagonists as full inhibitors of gastrin and partial inhibitors of vagally stimulated acid secretion (6). The involvement of ECL cells … 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.
In response to gastrin released by neighbouring G-cells, secreted histamine from ECL cells acts on parietal cells to stimulate the release of gastric acid. Histamine is stored primarily in the ECL cells that reside in the basal half of the oxyntic gland. 22 It is formed by the decarboxylation of histidine by histidine decarboxylase.

3. Histamin kommer från en cell i magsäcksslemhinnan (ECL-celler). Man vet inte exakt hur histaminet verkar på syrasekretionen – antingen aktiveras ECL av fotografia. Parietal cell of stomach wall, located in the gastric glands secretes hydrochloric acid. Beautiful colorful drawing on an abstract DIGESTIVE (L7) Flashcards | Quizlet.

The ECL cells are peptide-hormone-producing endocrine cells known to release histamine and chromogranin-A-derived peptides (such as pancreastatin) in response to gastrin. In conclusion, gastrin is responsible for most of the food‐evoked mobilization of ECL‐cell histamine. The histamine response to electrical vagal stimulation reflects the effect of circulating gastrin rather than a direct action of the vagus on the ECL cells. ECL cells are endocrine/paracrine cells located in the acid-producing part of the stomach.
