Background: Bradykinin receptor B2 is a constitutively expressed G protein-coupled receptor. In rats, the B2 receptors is present on non-peptidergic C-neurons, peptidergic C-neurons, dendrites and axons in A-neurons, NGF-responsive nociceptors. Recent research on rat TG neurons revealed that the B2 receptor is essential in the early stages of general pain generation and that endogenous bradykinin preferentially activates the B2 receptor over the B1 receptor. The activation of the B2 receptor by bradykinin stimulates neurogenic chloride secretion in the rat colon through COX increasing PGE2 production.
