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 histamine in response to stimulation by the hormones gastrin and pituitary adenylyl cyclase-activating peptide. The direct effect of galanin occurs in a neuroendocrine or paracrine fashion because galanin-positive nerve terminals are localized in close proximity to ECL cells in the rat stomach (89). These inhibitory actions of galanin on the ECL cell have been reproduced in … Endocrine cells of the gastric oxyntic mucosa, and especially the enterochromaffin-like cells (ECL), are the progenitors of gastrin-promoted proliferative lesions whose tumorigenic potential largely depends on the background condition in which they arise..

The histamine-containing ECL cells constitute the most abundant endocrine cell type in the acid-producing part of the rat stomach; they constitute 0.5–1.0% of all 

The best-known component of gastric juice is hydrochloric acid, the secretory product of the parietal, or oxyntic cell. It is known that the capacity of the stomach to secrete HCl is almost linearly related to parietal cell numbers. When stimulated, parietal cells secrete HCl at a concentration of roughly 160 mM (equivalent to a pH of 0.8). Most gastric carcinoids are enterochromaffin-like (ECL)-cell carcinoids; rarely, other types may occur in the stomach.

The ECL cells in the stomach produce, store and secrete a variety of secretory products, such as histamine and chromogranin A-derived peptides (e.g. pancreastatin). The functional significance of the ECL cells can be expected to reflect the nature/bioactivity of the secreted products. Although the anticipated peptide hormone of the ECL cells remains unidentified, ECL-cell histamine is

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. 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.

Changes in ECL-cell morphology were examined by immunocytochemistry and … in the stomach: the oxyntic mucosa and the antral mucosa. Parietal cells, which make up some 80% of the acid-secreting gastric mucosa, are located in the oxyntic mucosa. They are found proximally in the gastric body and fundus, intermingled with histamine-secreting enterochromaffin-like cells (ECL) and the main pepsinogen-secreting cells. Flag as Inappropriate Microdialysis was used to study how ischemia-evoked gastric mucosal injury affects rat stomach histamine, which resides in enterochromaffin-like (ECL) cells and mast cells. A microdialysis probe was inserted into the gastric submucosa, and the celiac artery … Gastrin (g) and enterochromaffin: Like (ecl) cells in the stomach of portocaval-shunted rats: Radioimmunological, immunocytochemical and ultrastructural study By Radosavljević Tatjana, Todorovoć Vera, Nikolić Ivan, Petakov Marijana D., Šikić Branka and Vučević Danijela Ischemia of rat stomach mobilizes ECL cell histamine Masayuki Kitano,1,3 Maria Bernsand,2 Yosuke Kishimoto,1 Per Norle´n,2 Rolf Ha˚kanson,2 Yoko Haenuki,1 Masatoshi Kudo,3 and Junichi Hasegawa1 1Department of Clinical Pharmacology, Faculty of Medicine, Tottori University, Tottori, Japan; 2Department of Pharmacology, Institute of Physiological Sciences, University of Lund, Lund, Sweden; ECL cells in the oxyntic mucosa of the mouse and rat stomach express CCK2 receptors, which enable them to respond to gastrin by the production and release of histamine. We have studied CCK2 receptor-deficient mice and rats subjected to Not to be confused with Enterochromaffin cell. Enterochromaffin-like cells or ECL cells are a type of neuroendocrine cell found in the gastric glands of the gastric mucosa beneath the epithelium, in particular in the vicinity of parietal cells, that aid in the production of gastric acid via the release of histamine.

Proteins participating in vesicular docking and fusion have been identified in the nervous system. Such proteins appear to be important for the molecular regulation of exocytosis also in non-neuronal cells. The enterochromaffin-like (ECL) cells of the gastric acid-secreting (oxyntic) mucosa secrete histamine and chromogranin A-derived peptides, such as pancreastatin.

It has been found recently, that a primary effector cell for stimulation of acid secretion is the (entero chromofin / ike) ECL cell, which is placed in close proximity to the parietal cells. It also contains the gastrin/CCKB receptor, as well as the cholinergic muscarin M 1 receptor, both of which, when activated, cause the ECL cell to release histamine.
