1 Apr 2020 Acute responses of rat stomach enterochromaffinlike cells to gastrin: Control of gastric acid secretion:the gastrin-ECL cell-parietal cell axis.

That this sequence of events occurs not only with omeprazole but also with other effective gastric antisecretory agents has been verified in the rat by giving the H2-receptor antagonist ranitidine as a continuous infusion. 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.

Dear Sir: In 1969, Rubin 1 pointed out that a proliferation of endocrine cells does occur in atrophic In contrast to the other two major gastric secretagogues, acetylcholine and histamine, gastrin only weakly stimulates the acid secretion in isolated parietal cells At similar gastrin levels, ECL-cell hyperplasia of the same magnitude developed during both ranitidine and omeprazole treatment. Antrectomy prevented the Thus, migration of both parietal cells and ECL cells is altered in gastrin-deficient mice. Gastrin is produced in antral G cells; histamine is found in mast cells, ECL cells and nerve fibers in the enteric plexus. Gastrointestinal mast cells are involved in Gastrin and acetylcholine produce typical biphasic calcium signals. Inhibition of ECL cell histamine release and calcium signaling is produced by somatostatin 2004), but are indirectly linked to ECL-cell activity since reduced activity of ECL cells reduces gastric acid secretion, which in turn increases the activity of G cells ( culating gastrin. The present review presents current knowledge of the biology and physiology of the rat stomach ECL cells. Examination of serially sectioned gastrin stimulates acid secretion through release of ECL cell histamine.

The ECL cells start to proliferate. The antral mucosa, if biopsied, will exhibit gastrin cell hyperplasia. Finally, the end stage is similar to the florid stage, with nearly complete oxyntic gland loss, marked epithelial metaplasia, and ECL-cell hyperplasia, but reduced inflammation.

Detta talar för att ECL-cellerna inte produderar något kalciotropt hormon, då celler som producerar dylika hormon borde vara känsliga för förändringar i blod-kalciumnivåerna. Dock kan det ej uteslutas att ECL-cellerna producerar ett osteotropt hormon.

The absence of gastrin immunostaining indicated sampling from the body or fundus, and these cases then underwent immunohistochemical staining with chromogranin (clone LK2H10, 1:100 dilution; Cell Marque) and were evaluated for the presence or absence of ECL cell hyperplasia (defined as linear or nodular aggregates of at least 5 ECL cells 3, 6). ECL cell density in patients with duodenal ulcer disease. If this is confirmed, an increase in the ECL cell mass could partly explain the increased acid secretion in these patients since the magnitude of the gastrin-stimulated histamine release is dependent on the ECL cell mass (49, 50).

Interestingly, gastrin stimulation also increased ECL cells expression of anti-apoptotic genes.

Background & Aims: Gastrin stimulates acid secretion from parietal cells and histamine release from enterochromaffin-like (ECL) cells through identical gastrin receptors.
