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. The ECL cells are endocrine/paracrine cells in the acid-producing part of the stomach. They secrete histamine in response to circulating gastrin. Gastric submucosal microdialysis has been used to study ECL-cell histamine mobilization in awake rats.

Gastrin stimulates ECL cells 2020-09-16 · Enterochromaffin-like (ECL) cells in the stomach lining; Histamine-releasing (histaminergic) neurons; In people with histamine intolerance, food allergies, IBD, and IBS, the histamine system may become dysfunctional. Histamine builds up and strays from its typical behavior. Our journals promote pharmacology in all its forms by disseminating the latest high quality research in our peer reviewed scientific journals. 2019-02-26 · Histamine is released at the mucosal surfaces as a result of exposure to foreign particles. This histamine release causes the capillaries to become more permeable to white blood cells, which move 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).

They are also considered a type of enteroendocrine cell.

(ECL-cell at top center.) Latin: endocrinocytus ECL: MeSH: Enterochromaffin-like+Cells: Code TH H3.04.02.0.00030 Enterochromaffin-like cells or ECL cells are a type of neuroendocrine cells found in the gastric glands of the gastric mucosa beneath the epithelium, in particular in the vicinity of parietal cells. Flag as Inappropriate 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. 1999-11-01 · HISTAMINE SECRETION FROM ECL CELLS Histamine secretion from ECL cells is of critical importance for gastric acid secretion. In vivo studies have shown that the antral hormone gastrin is the main stimulus for acid secretion and histamine release. AIM: Gastrin stimulates acid secretion by mobilizing histamine from enterochromaffin-like (ECL) cells that occur predominantly at the base of the gastric glands.

d. 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. (ECL-cell at top center.)

In the present study, we used a panel of five HDC antisera and one histamine antiserum to investigate whether histamine and HDC are exclusive to the ECL cells.

September 1979 EM IDENTIFICATION OF RAT GASTRIC HISTAMINE CELLS 461 represented ECL cells such as the ones illustrated in Figures 2-5. Although the majority of apparent en- docrine cells appeared heavily labeled, many others appeared unlabeled or only weakly labeled (Figure 1). Furthermore, it seems to be a general principle that stimulation of function (which, for the ECL cell, is release of histamine) in a parallel way stimulates the proliferation of the same cell. Long-term hyperstimulation of cell division predisposes to genetic changes and, thus, development of tumours.
