Activity summary

H2R also known as histamine H2 receptor is a G-protein-coupled receptor with a mass of approximately 40 kDa. It is expressed mainly in the gastric parietal cells as well as in the heart brain and various immune cells. H2R modulates gastric acid secretion by engaging in the interaction with histamine which activates the receptor. This activation includes changes in intracellular cyclic AMP levels and subsequent cellular responses.

Biological function summary

The histamine H2 receptor plays a significant role in the mediation of gastric acid secretion cardiac muscle contraction and immune response modulation. Although it functions independently it does interact with other receptors giving a context like mast cells which secrete histamine. These receptors play an important role in stimulating gastric parietal cells to produce acid as well as having involvement in the modulation of heart rate and force of contraction.

Pathways

H2R participates in the GPCR signaling pathway and adenylate cyclase activation both of which are critical for physiological responses in gastric acid secretion and modulation of cardiac function. H2R interacts with proteins such as adenylate cyclase and other H receptors like H1 receptor contributing to the regulation of varied responses across tissues like the stomach heart and brain.

Associated diseases and disorders

H2R is strongly related to peptic ulcers and gastroesophageal reflux disease (GERD). In these conditions excessive secretion of gastric acid due to H2R overactivity can lead to mucosal damage and discomfort. Moreover other histamine receptors like H1 receptor might influence inflammatory processes and allergy drawing connections that are relevant to understanding histamine's overall impacts in the body.
