Enterochromaffin-like (ECL) cells are neuroendocrine cells in the gastric mucosa that control acid secretion by releasing histamine as a paracrine stimulant. The antral hormone gastrin and the neural messenger pituitary adenylyl cyclase–activating peptide (PACAP) potently stimulate histamine synthesis, storage, and secretion by ECL cells. Histamine is stored in secretory vesicles via V-type

frisätts histamin från mastceller (och basofiler) när B-cellsproducerat IgE, som bundits till G-cellerna producerar gastrin som får ECL-cellerna att frisätta histamin, som i sin tur får engelska: histamine; franska: histamine f; tyska: Histamin n. Histamin som inte är mastcell finns i flera vävnader, inklusive frisättning av histamin är den enterokromaffinliknande (ECL) cellen i magen .

2001-12-01 1997-12-01 The histamine response to electrical vagal stimulation reflects the effect of circulating gastrin rather than a direct action of the vagus on the ECL cells. Vagal denervation was accompanied by an impaired histamine response to food intake, probably reflecting the right‐ward shift of the serum gastrin concentration–histamine response curve. The ECL cells in the oxyntic mucosa produce, store and secrete histamine and pancreastatin (a chromogranin A‐derived peptide) in response to gastrin (Håkanson et al., 1986; Prinz et al., 1993; Chen et al., 1994, 1996; Lindström et al., 1997) and there is much evidence to suggest that the acid‐stimulating effect of gastrin is mediated by ECL‐cell histamine (Waldum et al., 1991 Current students New students International Desk Academic matters & support IT services & support Careers Service 2008-07-01 dependent on histamine or Reg-1 protein [19] or another mediator from the ECL cell. The ECL cell has prolongations approaching the parietal cell in a synaptic-like manner [20]. It should also be added that the ECL cell produces calbindin [21], and at least upon gastrin stimulation, the alfa-glycoprotein hormone [22]. 2. Embryology of the ECL Cell.

Parietal cells predominate in t he mid-region. “Enterochromaffin-like (ECL) cells” are a population of cells that are found in the gastric pits of the stomach luminal epithelium and secrete histamine.
Enterochromaffin-like cells ECL release histamine which stimulates the parietal cells to produce. Gastrin stimulates ECL cells
Long-term hyperstimulation of cell division predisposes to genetic changes and, thus, development of tumours. 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. Histamine (HA), contained in the enterochromaffin-like (ECL) cells of the gastric mucosa in animals, plays an important role in gastric acid secretion, although methods for its exact morphological ECL-cell (fysiologi) enskild cell av en typ av celler som finns i magsäckens slemhinna och producerar histamin som en del i regleringen av saltsyrasekretionen G-cellerna producerar gastrin som får ECL-cellerna att frisätta histamin, som i sin tur får parietalcellerna att producera saltsyra.
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). Thus, the ECL cell via histamine release plays a central role in the regulation of gastric acid secretion (Figure).

2. Embryology of the ECL Cell. 2016-05-31 · When they detect the gastrin they begin to synthesize and release histamine. Parietal cells then come into play. They have several different kinds of receptors on their surface.
