It is known that the capacity of the stomach to secrete HCl is almost linearly related to parietal cell numbers. When stimulated, parietal cells secrete HCl at a concentration of roughly 160 mM (equivalent to a pH of 0.8). Most gastric carcinoids are enterochromaffin-like (ECL)-cell carcinoids; rarely, other types may occur in the stomach. (Refer to Table 1 in the Cellular and Pathologic Classification of GI Carcinoid Tumors section of this summary for more information.) Type I ECL-cell gastric carcinoids, the most common type, typically do not have clinical also restricted to the ECL cell or is conducted by both cells, as is currently believed.“-‘“.‘7.27 The purpose of the present study is to identify by EM radioautography the histamine-synthesizing en- docrine cells in the rat stomach. In this study, rat It has been found recently, that a primary effector cell for stimulation of acid secretion is the (entero chromofin / ike) ECL cell, which is placed in close proximity to the parietal cells.

ECL cell, which is placed in close proximity to the parietal cells. It also contains the gastrin/CCKB receptor, as well as the cholinergic muscarin M 1 receptor, both of which, when activated, cause the ECL cell to release histamine.

Proteins participating in vesicular docking and fusion have been identified in the nervous system. Such proteins appear to be important for the molecular regulation of exocytosis also in non-neuronal cells.

This material is formed as a consequence of autophagocytosis and peroxidation of the products undergoing degradation.

1999-05-01 Recently, we showed that the ECL cells in the oxyntic mucosa of the rat stomach are an important source of circulating pancreastatin, a fragment of chromogranin A. The present study examined how much the ECL cells contribute to the circulating levels of pancreastatin during omeprazole-evoked hypergastrinemia. Rats received omeprazole (400 mumol kg-1 day-1) by the oral route for 3 weeks. The ECL cells in the oxyntic mucosa of rat stomach produce histamine and chromogranin A-derived peptides such as pancreastatin. The cells respond to gastrin via cholecystokinin-2 (CCK2) receptors. A CCK2 receptor blockade was induced by treatment (for up to 8 weeks) with two receptor antagonists, YM022 and YF476. Changes in ECL-cell morphology were examined by immunocytochemistry and … in the stomach: the oxyntic mucosa and the antral mucosa. Parietal cells, which make up some 80% of the acid-secreting gastric mucosa, are located in the oxyntic mucosa.
