Clinical, histological, histochemical and ultrastructural characteristics of eight cases of carcinoid tumors of the non‐antral portion of the stomach are presented. Four cases with multiple polypoid lesions are accompanied by an increased level of gastrin. A normal level of gastrin was present in the other four cases with isolated tumor and a normal component of endocrine cells in the

ECL cells expressed this receptor, whereas gastrin receptor immunoreactivity on parietal cells was ambiguous [30]. In any way, the ECL cell can proliferate and develop into neoplasia, and gastrin has a positive trophic e ect on this cell through its gastrin receptor. 3. Background & Aims: Gastrin stimulation of the type 2 cholecystokinin (CCK2) receptor results in ECL cell proliferation and histamine secretion. This report describes the effects of targeted disruption of the CCK2 receptor gene on ECL cell morphology and function. Methods: The ECL cells in the oxyntic mucosa of CCK2 receptor–deficient (knockout [KO]) vs. wild-type (WT) mice were investigated 1997-02-01 The ECL cells constitute the predominant endocrine cell population of the stomach.

ECL-cells tumör typ III är sällsynta, vanligen solitära och beter sig malignt, medan ECL-cellstumörer av typ I och II ofta är multipla, små (4-10 mm) och lågmaligna (se ”Benigna ventrikeltumörer”). Ett användbart diagnostiskt verktyg vid misstanke om endokrincellstumör är octreotidscintigrafi. Octreotid, en somatostatinanalog Carcinoider i magslemhinnan utgår från de så kallade ECL-cellerna (enterochromaffin like cells). De indelas i 3 undergrupper: ECLom typ 1: Utvecklas vanligen hos patienter med kronisk atrofisk gastrit. Den patofysiologiska bakgrunden är stigande gastrinnivåer som svar på utebliven syrasekretion i ventrikeln. Endocrine cells of the gastric oxyntic mucosa, and especially the enterochromaffin-like cells (ECL), are the progenitors of gastrin-promoted proliferative lesions whose tumorigenic potential largely depends on the background condition in which they arise. ECL-celler Cardiakörtlarna och antrumkörtlarna producerar huvudsakligen slem, medan huvudkörtlarna förutom slem även producerar saltsyra och pepsinogen, ett förstadium till pepsin samt enzymet lipas och hormonet leptin.

böjningsform av ECL-cell; In gastric enterochromaffin-like (ECL) cells, stimulation with gastrin leads to a prompt biphasic calcium response followed by histamine secretion. This study investigates the underlying signaling events in this neuroendocrine cell type. In ECL cells, RT-PCR suggested the presence of inositol 1,4,5-trisphosphate receptor (IP(3)R) subtypes 1-3.

ECL cells [ECL cell] [enterochromaffin-like cells] These cells (Pearse et al, 1970) - not to be confused with enterochromaffin cells - constitute more than 30 % of the neuroendocrine cells in the acid-secreting gastric epithelium (Prinz et al, 2003; Chen et al, 1998; Chen et al, 1999; Sundler et al, 1998; Hakanson et al, 1998; Zhao and Chen, 2012).

The present study examined gastrin-evoked ECL-cell responses over a 10-week time span in terms of ECL cell density in patients with duodenal ulcer disease. If this is confirmed, an increase in the ECL cell mass could partly explain the increased acid secretion in these patients since the magnitude of the gastrin-stimulated histamine release is dependent on the ECL cell mass (49, 50).

Anne E. Bishop, Enterochromaffin-like (ECL) cells, in contrast to EC cells, are Enterochromaffin-Like Cells. The The ECL cells are the predominant endocrine cell population in the oxyntic mucosa. They produce histamine, chromogranin A/pancreastatin and an as yet unidentified peptide hormone.
