These metabotropic receptors associated with the G inhibitory protein (Gi/o) reduce cyclic adenosine monophosphate (AMP) through adenyl cyclase inhibition, and induce an increase in potassium (14) by enhanced permeability of inflow and outflow channels, hyperpolarizing the postsynaptic neuron.
Vascular endothelium regulates the underlying smooth muscle layer and vascular tone by release of endothelium-derived relaxing factors such as nitric oxide (NO), prostaglandins, and endothelium-derived hyperpolarizing factor (EDHF) as well as vasoconstricting factors such as endothelin, superoxide (O2-), and thromboxane (25, 28-32).
