Although plasma gastrin levels were the same during treatment, the enterochromaffinlike (ECL) cell density increased approximately linearly with time at a rate correlated to the plasma gastrin level.

Enterochromaffin-like (ECL) cells, in contrast to EC cells, are confined to a single region of the gut, the gastric fundus, where they form the major endocrine cell population. ECL cells have no lumenal connection (Fig. 6). The cells are argyrophil but nonargentaffin.

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.

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 H 2 -receptor antagonist ranitidine as a continuous infusion.

The absence of gastrin in the gastrin KO mouse is associated with reduced parietal cell mass, inactivation of ECL cells and subsequent reduction of actively secreting parietal cells. Linear or nodular enterochromaffin-like (ECL) cell hyperplasia due to achlorhydria stimulating increased gastrin secretion from the antral G cells, which may lead to type 1 well differentiated neuroendocrine tumors Intestinal type dysplasia-adenocarcinoma sequence Antral changes often mimic reactive gastropathy and show G cell hyperplasia The presence of gastrin stimulates parietal cells of the stomach to secrete hydrochloric acid (HCl)/gastric acid. This is done both directly on the parietal cell [failed verification] and indirectly via binding onto CCK2/gastrin receptors on ECL cells in the stomach, which then responds by releasing histamine, which in turn acts in a paracrine manner on parietal cells stimulating them to Enterochromaffin-like (ECL) cellsalso bear gastrin receptors, and recent evidence indicates that this cell may be the most important target of gastrin with regard to regulating acid secretion. Gastrin is transferred from a specific type of G cell in the gastric epithelium to the ECL cells by blood. Histamine and gastrin act synergistically as the most important stimulators of hydrochloric acid secretion from parietal cells and stimulators of secretion of pepsinogen from chief cells .

ECL cells seems to be similar in different species, there are quantitative differences with regard to the ECL- cell density and possibly also the sensitivity of ECL cells to gastrin. BACKGROUND With the development of substituted benzimid- azoles, an entirely new principle for reducing gastric acid secretion was introduced. Inhibition is achieved

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. The enterochromaffin-like (ECL) cell in the oxyntic mucosa has a key role in the regulation of gastric secretion since it synthesizes and releases the histamine regulating the acid secretion from the parietal cell.

They are most prevalent in the acid-secreting regions of the stomach.

Gastrin is a hormone the stomach produces that stimulates the release of gastric acid.

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. The lack of demonstrable CCK B /gastrin receptors on rat parietal cells (Song et al., 1996) and the fact that depletion of ECL cell‐histamine completely abolishes gastrin‐evoked acid secretion (Andersson et al., 1996a) seem to favour the view that the ECL cells rather than the parietal cells are the major targets for gastrin. 1999-11-01 2020-07-07 In isolated ECL cells, PACAP was shown to efficiently stimulate ECL cell proliferation, even exceeding the effect of gastrin [ 23 ]. 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.
