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.

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.
