2001), they do respond with secretory activation to a number of neuropeptides present in neurones in the stomach wall, e.g. pituitary adenylate cyclase‐activating peptide (PACAP) and vasoactive intestinal peptide (VIP) (Lindström et al. 1997; Zeng et Many of the endocrine cells in the stomach are poorly characterized with respect to physiological significance. In some cases, the anticipated hormone has not yet been identified.

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.. Originating from the histamine-containing enterochromaffin-like (ECL) cells of the embryologic foregut, gastric carcinoid tumors represent the glandular stomach. The most significant alteration was a proliferation of argyrophil endocrine cells that was demonstrated to be enterochromaffin-like (ECL) cells. The ECL cell proliferation consisted of a continuum of changes involving diffuse hyperplasia, focal … 2020-10-02 ECL cell density in patients with duodenal ulcer disease.

Cell and tissue research 1998-3-28 ECL cells of the rat stomach: development of lipofuscin in response to sustained gastrin stimulation.

Mucosal mast cells are relatively few, occurring mainly at the surface of the mucosa and in the submucosa. ECL cells occur predominantly in the basal half of the mucosa.
