Histamin och histaminreceptor H4 vid inflammatoriska tillstånd

In the present study, we have identified distinct cell types in the gastric epithelium expressing a bitter receptor protein; thus, confirming and extending the results of previous studies, which demonstrated the presence of mRNA for bitter receptors in epithelial cells of the stomach (Wu et al., 2002; Vegezzi et al., 2014; Liu et al., 2017; Prandi et al., 2018). CCK-2 receptors are located on enterochromaffin-like (ECL) cells in corpus mucosa and gastrin stimulates acid production by releasing histamine from the ECL cells, which in turn stimulates the parietal cells. Whether parietal cells also possess gastrin receptors of physiological significance is unclear. Gastrin stimulates function (histamine release) and ECL cell proliferation in a parallel way.

It is predominantly found bound to G proteins of class G q that use 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. Parietal cells (also known as oxyntic cells) are epithelial cells in the stomach that secrete hydrochloric acid (HCl) and intrinsic factor.These cells are located in the gastric glands found in the lining of the fundus and body regions of the stomach.

Cholecystokinin (CCK) B /gastrin receptor blockade is known to suppress their activity. TMPH inhibited both basal and gastrin driven histamine secretion with a maximal effect (34 percent) (1.78 +/- 0.08 nmol/10(3) cells) and an IC50 of > 5 x 10(-7) M. H1 receptor antagonism did not cells called enterochromaffin-like (ECL) cells. ECL cells also have receptors for gastrin and acetylcholine, which stimulate histamine release. Histamine binds to the H2 receptor on the parietal cell, resulting in activation of adenylyl cyclase, which increases intra- cellular cyclic adenosine monophosphate (cAMP) and activates protein kinases that stimulate acid secretion by the H+/K+-ATPase. Histamine, released from ECL cells, is the most impor-tant direct stimulant of acid secretion, as shown by the broad efficacy of histamine-2 receptor antagonists as full inhibitors of gastrin and partial inhibitors of vagally stimulated acid secretion (6).

Activation of the enterochromaffin-like (ECL) cell is accepted as the main source of histamine participating in the regulation of acid secretion and is functionally and trophically controlled by gastrin, which is mediated by gastrin/CCK-2 receptors expressed on the ECL cell. The gastrin-ECL cell pathway has been investigated extensively in situ (gastric submucosal microdialysis), in vitro (isolated ECL cells) and in vivo (intact animals). Gastrin acts on CCK2 receptors to control the synthesis of ECL-cell histamine, accelerating the expression of the histamine-forming enzyme histidine decarboxylase (HDC) at both Enterochromaffin-like (ECL) cells also bear gastrin receptors, and recent evidence indicates that this cell may be the most important target of gastrin with regard to regulating acid secretion.
