Biochem/physiol Actions The histamine H2 receptor influences various cardiovascular responses, including vasodilation and cardiac rhythm, regulates gastric acid secretion, and also plays a role in the immune system by inhibiting antibody production, T cell proliferation and cytokine production. Histamine receptors are members of the GPCR family, and H2 mediates cell signaling via internalization and interaction with the GTPase dynamin. |
