We have examined how isolated ECL cells respond to a variety of neuromessengers and peptide hormones. Highly purified (85%) ECL cells were collected from rat stomach using repeated counter September 1979 EM IDENTIFICATION OF RAT GASTRIC HISTAMINE CELLS 461 represented ECL cells such as the ones illustrated in Figures 2-5. Although the majority of apparent en- docrine cells appeared heavily labeled, many others appeared unlabeled or only weakly labeled (Figure 1). Conclusion: As the histamine concentrations were higher in the tissue (microdialysate) than in blood, histamine seems to reach the parietal cells via the paracrine route.

Ecl cells histamine

They secrete histamine in response to circulating gastrin. Gastric submucosal microdialysis has been used to study ECL-cell histamine mobilization in awake rats. Histamine in the stomach occurs in endocrine cells (so-called enterochromaffin-like (ECL) cells), mast cells, and neurons. The ECL cells are peptide hormone-producing cells. In mammals they are located basally in the oxyntic gland area, in the chief-cell-rich region. Parietal cells predominate in t he mid-region.

Ecl cells histamine

“Enterochromaffin-like (ECL) cells” are a population of cells that are found in the gastric pits of the stomach luminal epithelium and secrete histamine. In response to gastrin released by neighbouring G-cells, secreted histamine from ECL cells acts on parietal cells to stimulate the release of gastric acid. What do chief cells secrete? ECL-cell histamine plays an important role in the regulation of gastric acid secretion, particularly in response to gastrin stimulation. The time-course responses of ECL cells to gastrin include Unlike mast cells and basophils, ECL cells and histaminergic neurons do not store histamine. Instead, the production and release of histamine in these cells depend on physiologic stimuli.

Y1 - 2005 NMU‐25 almost qualified as a stimulator of ECL cell histamine mobilization (90% increase, integrated response) while secretin exerted weaker stimulatory effects (35% increase). This is in line with the previously demonstrated weak stimulatory effect of NMU‐25 and secretin on isolated ECL cells (Lindström et al., 1997). a-FMHdirectly impaired parietal cell activity [46]. Basalacid secretion wasreducedbyapproximately 60percentin aX-FMH-treatedrats compared to vehicle-treated rats, suggesting an involvement of ECL-cell histamine in basal acid secretion. Howeverthe H2 antagonist ranitidine inhibited basal acid secretion by about 85 percent.

the digestive system. 3 a gastric secretion and its  Enterochromaffin-like cells or ECL cells are a type of neuroendocrine cell found in the gastric glands of the gastric mucosa beneath the epithelium, in particular in the vicinity of parietal cells, that aid in the production of gastric acid via the release of histamine. They are also considered a type of enteroendocrine cell. “Enterochromaffin-like (ECL) cells” are a population of cells that are found in the gastric pits of the stomach luminal epithelium and secrete histamine. In response to gastrin released by neighbouring G-cells, secreted histamine from ECL cells acts on parietal cells to stimulate the release of gastric acid. Results: The ECL cell carries the gastrin receptor, and gastrin regulates its function (histamine release) as well as proliferation.

Biological significance of ECL-cell - AVHANDLINGAR.SE

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.
