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. Linear or nodular enterochromaffin-like (ECL) cell hyperplasia due to achlorhydria stimulating increased gastrin secretion from the antral G cells, which may lead to type 1 well differentiated neuroendocrine tumors Intestinal type dysplasia-adenocarcinoma sequence Antral changes often mimic reactive gastropathy and show G cell hyperplasia Neuroendocrine cell proliferations of the stomach arise in various settings and show features ranging from hyperplasia to neoplasia; Alternate/Historical Names. WHO 2010 has changed back to neuroendocrine cell from endocrine cell for these lesions Endocrine cell hyperplasia and neoplasia are equivalent terms to those used below; Diagnostic Criteria High grade / poorly differentiated neuroendocrine carcinoma is covered separately. Gastric endocrine cell proliferations typically show features seen in other GI tract well differentiated endocrine proliferations.

The best-known component of gastric juice is hydrochloric acid, the secretory product of the parietal, or oxyntic cell. 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).

ECL site switcher and larynx cancers, oesophageal cancers (squamous cell carcinoma) and breast cancer (pre and postmenopause). Two or drinks a day (45 grams or more) increases the risk of stomach and liver cancer. Unexpected similarities: Learning about how brain cells communicate from the venus fly trap. Thomas excitability, slow closure, and external stomach formation in the Venus using gel electrophoresis and electrochemiluminescence (ECL).

2021-01-22 · In this article we will be discussing the production of gastric mucus in the stomach. We will be looking at the cells that make up the mucosa of the stomach, the process of producing mucus, the control mechanisms involved in its secretion and some clinical aspects of when things go wrong.

Histamine in the stomach occurs in endocrine cells (so-called enterochromaffin-like (ECL) cells), mast cells, and neurons. The ECL cells are peptide hormone-producing cells. In mammals they are located basally in the oxyntic gland area, in the chief-cell-rich region. Parietal cells predominate in t he mid-region. ECL cells respond readily to gastrin with histamine release and histamine resynthesis. The Histamine-Storing ECL Cell There are two types of histamine-storing cells in the stomach, ECL cells and classical mast cells. ECL cells are involved in the regulation of gastric acid secretion whereas mast cells are involved in mediating the immune response.

Hence, proteins engaged in vesicular docking and in the fusion of granule/vesicle membrane with plasma membrane seem to exist in both neurons and endocrine cells. THE ENTEROCHROMAFFIN-LIKE (ECL) CELL Physiological and pathophysiological role HELGE L. WALDUM, ARNE K. SANDVIK, UNNI SYVERSEN and EILIV BRENNA Histamine has a central role in the regulation of gastric acid secretion. This histamine is produced by and released from the enterochromaffin-like (ECL) cell which accordingly has a key-regulatory role There are two types of histamine-storing cells in the stomach, ECL cells and classical mast cells. ECL cells are involved in the regulation of gastric acid secretion whereas mast cells are involved in mediating the immune response. Mast cells originate in the bone marrow and migrate to the stomach.

Cell and tissue research 1998-3-28 ECL cells of the rat stomach: development of lipofuscin in response to sustained gastrin stimulation.

Mucosal mast cells are relatively few, occurring mainly at the surface of the mucosa and in the submucosa. ECL cells occur predominantly in the basal half of the mucosa.
