Generally, there is a close relationship between regulation of function and growth, which is also true for the ECL cell. Thus, gastrin is the most important regulator of ECL cell function, as well as proliferation. Hypergastrinemia induces ECL cell hyperplasia up to a certain level, at which a new equilibrium is reached [ 32].

Altered influence of CCK-B/gastrin receptors on HDC expression in ECL cells after neoplastic transformation. Artikel i vetenskaplig tidskrift, refereegranskad.

Gastrin from G cells in the antrum is the av M Björkqvist · 2002 — In response to gastrin, they secrete histamine, that in turn stimulates the parietal cell to secrete acid. The first aim of the study was to prepare isolated ECL cells ECL cells respond to GASTRIN by releasing histamine which acts as a paracrine stimulator of the release of HYDROCHLORIC ACID from the GASTRIC Altered influence of CCK-B/gastrin receptors on HDC expression in ECL cells after neoplastic transformation. Artikel i vetenskaplig tidskrift, refereegranskad. Loxtidine (2g/l) was administered in drinking water for 48 weeks to allow multiple ECL cell carcinoids to develop.

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. 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. Role of gastrin in the development of gastric mucosa, ECL cells and A-like cells in newborn and young rats.

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).

Gastrin increases histamine production by stimulating histidine decarboxylase activity (Fig. 4). Treatment of ECL cells with pertussis toxin inhibits the effects of gastrin on histidine decarboxylase activity, suggesting the involvement of G i/o in this process. 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 Thus, the ECL cell and its main regulator, gastrin, are central in human gastric carcinogenesis, which make new possibilities in prevention, prophylaxis, and treatment of this cancer. Causes of cells called enterochromaffin-like (ECL) cells.

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).

1996a). The receptors for the cholecystokininigastrin family of The ECL cell may play an important role in gastric carcinogenesis also indirectly by the release of Reg protein, which has been shown to stimulate proliferation of gastric cells and differentiation along parietal and chief cell lineages , and thus mediate the general trophic effect of gastrin on oxyntic mucosa . Gastrin is one of the hormones responsible for the process. Understanding gastrin and its relationship to digestion can help individuals make better choices about their health.

Gastrin is released into the blood and stimulates parietal cells to secrete the in the stomach that plays an important role is the enterochromaffin-like cell (ECL

The present study describes the development of lipofuscin in the ECL cells of the rat stomach. These cells produce and The ECL cells in the oxyntic mucosa secrete histamine in response to gastrin, stimulating parietal cells to produce acid.

This study investigates the underlying signaling events in this neuroendocrine cell type. In ECL cells, RT-PCR suggested the presence of inositol 1,4,5-trisphosphate receptor (IP (3)R) subtypes 1-3. 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. Gastrin is the main regulator of the ECL cell function and growth.

In gastric enterochromaffin-like (ECL) cells, stimulation with gastrin leads to a prompt biphasic calcium response followed by histamine secretion. This study investigates the underlying signaling events in this neuroendocrine cell type. In ECL cells, RT-PCR suggested the presence of inositol 1,4,5-trisphosphate receptor (IP (3)R) subtypes 1-3.

Inhibition is achieved Thus, the ECL cell and its main regulator, gastrin, are central in human gastric carcinogenesis, which make new possibilities in prevention, prophylaxis, and treatment of this cancer.

We are therefore faced with the paradox of an effec-tive in vitro stimulant of gastric ECL cell function acting as an inhibitor of acid secretion in vivo (18, 19). The studies discussed here show that PACAP is an effec-tive ligand on PAC1 of isolated ECL cells (and of ECL cells Since gastrin‐evoked histamine mobilization from isolated ECL cells was dose‐dependently inhibited by the anaesthetic agents used in this study (except urethane), we propose that the suppressive effect is exerted directly on the ECL cell.
