چکیده

In gastric parietal cells the histamine H2 receptor is involved in gastric acid secretion. Molecular cloning of the cDNA for the histamine H2 receptor has revealed that the receptor is a member of the G-protein coupled receptor family. We expressed histamine H2 receptors in CHO cells, COS7 cells, and Sf9 cells to analyze N-glycosylation, palmitoylation, and desensitization of the H2 receptor, which are difficult to analyze in isolated parietal cells. The findings obtained in these systems will be useful for studying the gastric acid secretion mechanisms in parietal cells.

In vitro radioprotective effects of histamine H2 receptor antagonist against gamma-rays induced chromosomal aberrations in human lymphocytes.

Background: Radioprotective capability of histamine H2 receptor antagonists have been shown in several in vivo studies mainly using animal models. However, to verify the effectiveness of these agents in clinical applications, studies should be performed on human cells. In the present study radioprotective properties of these agents was examined in vitro on human lymphocytes using metaphase anal...
