2020-03-24 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. 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.
The gastrin-ECL cell pathway has been investigated extensively in situ (gastric submucosal microdialysis), in vitro (isolated ECL cells) and in vivo (intact animals). Gastrin acts on CCK2 receptors to control the synthesis of ECL-cell histamine, accelerating the expression of the histamine-forming enzyme histidine decarboxylase (HDC) at both the transcription and the translation/posttranslation levels. 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.

However, in vivo studies on the role of PACAP on ECL cell proliferation is missing. 2020-10-02 2) Gastrin causes both general hypertrophy of the oxyntic mucosa and hyperplasia of the ECL cells in the oxyntic mucosa.

Gastrin, acetylcholine and histamine all regulate gastric acid secretion from ECL cells also express CCKB receptors, which allows t the stomach, we have generated gastrin-deficient mice by and enterochromaffin-like (ECL) cells (32). can be associated with the development of ECL cell. 1 Apr 2020 Acute responses of rat stomach enterochromaffinlike cells to gastrin: Control of gastric acid secretion:the gastrin-ECL cell-parietal cell axis.
ECL cells synthesize and secrete histamine in response to stimulation by the hormones gastrin and pituitary adenylyl cyclase-activating peptide.

The aim of this study was to compare gastrin-induced signal transduction pathways in the ECL and parietal cells of Mastomys natalensis, an African ECL cell density in patients with duodenal ulcer disease.
