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.

In one experiment, histamine mobilization in response to gastrin 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). The ECL cell ▪ Abstract Enterochromaffin-like (ECL) cells are neuroendocrine cells in the gastric mucosa that control acid secretion by releasing histamine as a paracrine stimulant. 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.

A, Ca 2+-induced histamine release by digitonin-permeabilized ECL cells is inhibited by BoNT/A. Permeabilized ECL cells were preincubated for 15 min at 30 C without (control) or with 100 n m BoNT/A in potassium glutamate buffer, followed by stimulation with potassium glutamate buffer without (clear column) or with 30 μ m free Ca 2+ (filled column) for 10 min at 30 C. Histamine released into 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. Long-term hyperstimulation of cell division predisposes to genetic changes and, thus, development of tumours. a-FMHdirectly impaired parietal cell activity [46].

Histamin som inte är mastcell finns i flera vävnader, inklusive frisättning av histamin är den enterokromaffinliknande (ECL) cellen i magen .

Gastrin itself is secreted by cells in the epithelium of the stomach, but travels to ECL cells via the blood. The ECL cells are endocrine/paracrine cells in the acid-producing part of the They secrete histamine in response to circulating gastrin.

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. Long-term hyperstimulation of cell division predisposes to genetic changes and, thus, development of tumours.

Gastrin itself is endocrine and ECL cells and plasma histamine levels (all P<0·001). Octreotide LAR did not affect ciprofibrate stimulation of gastrin cells, but all parameters of Histamine is produced in ECL cells by decarboxylation of L-histidine by histidine decarboxylase (HDC).

Another important site of histamine storage and release is the enterochromaffin-like (ECL) cell of the stomach. The most important pathophysiologic mechanism of mast cell and basophil histamine release is immunologic. These cells, if sensitized by IgE antibodies attached to their membranes, degranulate when exposed to the appropriate antigen.

Histamine stimulates the parietal cells to secrete HCl. The gastrin-ECL cell pathway has been investigated extensively in situ (gastric submucosal microdialysis), in vitro (isolated ECL cells) and in vivo (intact animals).
