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 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). Pa-

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. They respond to gastrin by the release of secretory products; more long-term responses include adaptation to the gastrin stimulus, hypertrophy and hyperplasia. ECL cell activation may be defined as the actions of regulatory factors that stimulate or inhibit histamine synthesis or secretion; the release of chromogranin A and its proteolytic product pancreastatin also are relevant, but histamine is the only product from the ECL cell that directly stimulates acid secretion by the parietal cell. ECL-celler svarar på gastrin från G-celler och de frisätter histamin vilket stimulerar parietalcellerna att producera magsaft. Sjukdomar [ redigera | redigera wikitext ] De neuroendokrina stamcellerna som ger upphov till enterokromaffina celler i bronkepitelet kan vara ursprungscellerna till småcellig lungcancer . 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”).

They are often discovered during endoscopy for reflux, anemia, or other reasons; and are typically multifocal. Baseline endothelial cell density (ECD) was 2,432 cells/mm 2 for CyPass patients and 2,434 cells/mm 2 for control patients.
