The mechanism of adrenoreceptors. Adrenaline or noradrenaline are receptor ligands to either α1, α2 or β-adrenoreceptors. α1 couples to Gq, which results in increased intracellular Ca and subsequent smooth muscle contraction. α2, on the other hand, couples to Gi, which causes a decrease in neurotransmitter release, as well as a decrease of cAMP activity resulting in smooth muscle contraction. … WebJan 20, 2024 · Epinephrine is an endogenous catecholamine that acts on beta-1, beta-2, and alpha-receptors.
