Definition
English
:
A class of
histamine
receptors discriminated by their
pharmacology
and mode of action.
Histamine
H2 receptors act via G-proteins to stimulate
ADENYLYL CYCLASES
. Among the many responses mediated by these receptors are
gastric acid
secretion, smooth
muscle relaxation
, inotropic and chronotropic effects on heart muscle, and inhibition of lymphocyte function. (From Biochem Soc Trans 1992 Feb;20(1):122-5)
