Summary
| Description |
English: 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 Ca2+ 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. β receptors couple to Gs, and increases intracellular cAMP activity, resulting in e.g. heart muscle contraction, smooth muscle relaxation and glycogenolysis. |
