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.

The ECL cells are controlled by a complex regulatory system involving endocrine, paracrine and neural pathways. The physiological significance of ECL cells reflects the nature of their products such as histamine, chromogranin A-derived peptides, Reg protein and yet-unknown hormone. 1999-11-01 · enterochromaffin-like (ECL) cells are endocrine cells of the gastric mucosa, constituting ∼1–3% of the fundic epithelial cell volume.
In ECL cells, RT-PCR suggested the presence of inositol 1,4,5-trisphosphate receptor (IP(3)R) subtypes 1-3. Electrochemiluminescence (ECL) microscopy is successfully applied to image cells, micro-/nano-objects, and electrochemical processes at electrode surfaces. The classic ECL tandem system is composed of the [Ru(bpy)3]2+ luminophore with the very efficient tripropylamine (TPA) coreactant. The dramatic decrease of the ECL signal observed when recording successive ECL images constitutes a key Flag as Inappropriate ECL cells expressed this receptor, whereas gastrin receptor immunoreactivity on parietal cells was ambiguous . In any way, the ECL cell can proliferate and develop into neoplasia, and gastrin has a positive trophic effect on this cell through its gastrin receptor. 1999-11-15 The ECL cell also contains the endocrine polypeptide chromogranin A (CGA) and CGA-derived peptides such as pancreastatin. The aim of the study was to identify regulators of secretory activity in isolated and purified ECL cells and to elucidate their signal transduction pathways.
The importance of ECL cells was accentuated when hyperplasia of these cells was ob-served under therapy with proton pump inhibitors in humans (17, 41, 57, 79). Antisecretory therapy … In gastric enterochromaffin-like (ECL) cells, stimulation with gastrin leads to a prompt biphasic calcium response followed by histamine secretion.
ECL cells expressed this receptor, whereas gastrin receptor immunoreactivity on parietal cells was ambiguous . In any way, the ECL cell can proliferate and develop into neoplasia, and gastrin has a positive trophic effect on this cell through its gastrin receptor.
Chormogranin A (CgA)-derived peptides, such as pancreastatin, are co-secreted with histamine. Many of the endocrine cells in the stomach are poorly characterized with respect to physiological significance.
Histamine‐secreting ECL cells are numerous in the oxyntic mucosa of the vertebrate stomach (Håkanson et al. 1986).They operate under the control of circulating gastrin (Håkanson et al. 1974, 1994).Histamine is mobilized from the ECL cells to stimulate acid secretion from adjacent parietal cells (Sandvik et al. 1987; Håkanson & Sundler, 1991; Waldum et al. 1991).

ECL cells are endocrine/paracrine cells located in the acid-producing part of the stomach. They are important regulators of gastric acid secretion in the stomach by virtue of their histamine synthesizing and secreting capacity.

Many of the endocrine cells in the stomach are poorly characterized with respect to physiological significance. In some cases, the anticipated hormone has not yet been identified. Global gene expression analysis of mouse stomach was performed in an attempt to identify the ECL-cell peptide/protein. Specific functional activation (omeprazole-induced hypergastrinaemia) was used as a tool to
They produce HISTAMINE and peptides such as CHROMOGRANINS. ECL cells respond to G-cellerna producerar gastrin som får ECL-cellerna att frisätta histamin, som i sin tur får parietalcellerna att producera saltsyra. Se även: G-cell, parietalcell av E Lindström · 2000 — Histamine in turn stimulates parietal cells to secrete acid.

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. Gastric cancer has reduced prevalence, but poor prognoses. To improve treatment, better knowledge of carcinogenesis and cells of origin should be sought. Stomach cancers are typically localized to one of the three mucosae; cardial, oxyntic and antral.
They play a key role in the control of acid secretion because of their ability to secrete histamine, which stimulates adjacent acid-producing cells (for reviews see Håkanson et al.1994, 1998). The ECL cell hyperplasia and neoplasia has been reported in patients with atrophic gastritis, in patients with sporadic gastrinoma 8 and patients with gastrinoma as a part of MEN I. 9 Long‐term PPI treatment is another condition with gastric hypo/anacidity and secondary hypergastrinemia. 6 It has been known that treatment/dosing with efficient inhibitors of acid secretion causes ECL cell ECL MOVIL, Ecatepec de Morelos.
