Intrinsic factor (IF), also known as gastric intrinsic factor (GIF), is a glycoprotein produced by the parietal cells (in humans) or chief cells (in rodents) of the stomach.

A CCK2 receptor blockade was induced by treatment (for up to 8 weeks) with two receptor antagonists, YM022 and YF476. Changes in ECL-cell morphology were examined by immunocytochemistry and We recenlty studied the G‐cell, d ‐cell and ECL‐cell density in a case of G‐cell hyperplasia. The 70‐year‐old patient has been treated for persistent gastric ulcers with a markedly increased plasma gastrin (5600 pg/mL). The stomach was surgically resected because of the obstruction associated with ulcer scars.

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. 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). Most gastric carcinoids are enterochromaffin-like (ECL)-cell carcinoids; rarely, other types may occur in the stomach.

1999-05-01 Recently, we showed that the ECL cells in the oxyntic mucosa of the rat stomach are an important source of circulating pancreastatin, a fragment of chromogranin A. The present study examined how much the ECL cells contribute to the circulating levels of pancreastatin during omeprazole-evoked hypergastrinemia. Rats received omeprazole (400 mumol kg-1 day-1) by the oral route for 3 weeks. The ECL cells in the oxyntic mucosa of rat stomach produce histamine and chromogranin A-derived peptides such as pancreastatin.

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 histamine in response to stimulation by the hormones gastrin and pituitary adenylyl cyclase-activating peptide.

Arnold and Koop 2 noted that ECL cells are almost exclusively restricted to the fundic mucosa and account for 40-60% of the endocrine cells in this part of the stomach. The number of ECL cells found in the gastric body in our study using anti-HDC IHC was lower than the numbers of D cells found in the control group and in the PPI group, with or without HP infection. Carcinoid tumours are of neuroendocrine cell origin and in the stomach arise from enterochro-maffin (EC) or enterochromaffin-like (ECL) cells, the latter comprising the major endocrine cell type in the body ofthe stomach.'3 The neuroendocrine cells in the bodyofthe stomachhavebeenshownto proliferate in patients with pernicious anaemias13-16 2020-06-11 · Type 1: Associated with autoimmune gastritis→destruction of parietal cells→decreased stomach acid →compensatory hyperplasia of antral G-cells (to try to signal to make more acid)→secrete gastrin → ECL cell hyperplasia and NET formation Type 2: Zollinger-Ellison syndrome with a duodenal or pancreatic gastrin-secreting NET, which stimulates Abstract. The ECL cells in the oxyntic mucosa of rat stomach produce histamine and chromogranin A-derived peptides such as pancreastatin. The cells respond to gastrin via cholecystokinin-2 (CCK2) receptors.

In addition, mucosal mast cells may also affect exocrine/endocrine functions of the stomach, especially in those species where they outnumber ECL cells (7).
