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.

The ECL cell may also produce other mediators. Ericsson, Peter et al. "ECL Cell Histamine Mobilization Studied byGastric Submucosal Microdialysis in Awake Rats:Methodological Considerations.".

They produce HISTAMINE and peptides such as CHROMOGRANINS.

(38). Histamine from the ECL cells being mainly located at the base of the glands (7), may reach the parietal cell not only by the paracrine route but also via the capillaries ( 18). Thus, the ECL cell via histamine release plays a central role in the regulation of gastric acid secretion (Figure).

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 2016-01-25 Which of the following hormones stimulates the secretion of histamine from the ECL cells? a. Enterogastrone.

23 Histamine, released from ECL cells, stimulates acid secretion primarily by interacting with H 2 receptors on parietal cells. Gastrin increases the expression of several genes in ECL cells that are important for histamine synthesis and storage; these include histidine decarboxylase (HDC), which makes histamine from histidine; vesicular monoamine transporter type (VMAT2), which transports histamine into secretory vesicles; and chromogranin A, which is co-stored with histamine in secretory vesicles (Fig. 3). (38). Histamine from the ECL cells being mainly located at the base of the glands (7), may reach the parietal cell not only by the paracrine route but also via the capillaries ( 18).

The ECL-cell histamine mobilization was independent of the concentrations of Ca2+ in the perfusion medium (0-3.4 mmol/l Ca2+). In one experiment, histamine mobilization in response to gastrin (10 nmol/kg/hr subcutaneously) was monitored in rats pretreated with prednisolone (60 mg/kg) or indomethacin (15 mg/kg). 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). Furthermore, it seems to be a general principle that stimulation of function (which, for the ECL cell, is release of histamine) in a parallel way stimulates the proliferation of the same cell.
