HDAC4 promotes nasopharyngeal carcinoma progression


A gene expression fingerprint of mouse stomach ECL cells.

Pa- 2020-06-25 ECL cell histamine mobilization and parietal cell stimulation in the rat stomach studied by microdialysis and electron microscopy. Fykse V(1), Solligård E, Bendheim MØ, Chen D, … 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. Histamine in turn stimulates parietal cells to secrete acid.

En annan typ av krombindande celler finns bara i magsäcksväggen och kallas enterokromaffin-liknande celler (ECL).

Sep 17, 2020 Stem cells that reside in the stomach are thus essential for regulating G cells, D cells, and ECL cells) and tuft cells, make up gastric glands. In the corpus of the stomach, the vagus nerve not only stimulates the parietal cell directly by releasing ACh, it also stimulates both ECL and D cells. Vagal  The pyloric gland area contains G cells that produce and secrete the hormone, gastrin. acetylcholine and gastrin promote histamine secretion from ECL cells Neuroendocrine cells in the glands of the GASTRIC MUCOSA. They produce HISTAMINE and peptides such as CHROMOGRANINS.

Ecl cells

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. 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 cells play a pivotal role in the peripheral regula-tion of acid secretion. 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 with proton pump inhibitors or H 2-receptor antagonists re- Type I ECL-cell gastric carcinoids, the most common type, typically do not have clinical symptoms. 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.

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.

They secrete histamine which is a major stimulator of acid secretion. Chormogranin A (CgA)-derived peptides, such as pancreastatin, are co-secreted with histamine.

Obestatin/ghrelin cells in normal mucosa and endocrine

In response to gastrin released by neighbouring G-cells, secreted histamine from ECL cells acts on parietal cells to stimulate the release of gastric acid. Enterochromaffin-like or ECL cells are a distinctive type of neuroendocrine cell in the gastric mucosa underlying the epithelium. They are most prevalent in the acid-secreting regions of the stomach. ECL cells synthesize and secrete histaminein response to stimulation by the hormones gastrinand pituitary adenylyl cyclase-activating peptide. 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.
