The adrenergic receptors are located primarily in the kidney, cardiac myocytes, nodal tissue, and other cardiac conduction tissue. [8] WebAbstract. Beta-blockers are widely used molecules that are able to antagonize β-adrenergic receptors (ARs), which belong to the G protein-coupled receptor family and receive their stimulus from endogenous catecholamines. Upon β-AR stimulation, numerous intracellular cascades are activated, ultimately leading to cardiac contraction or vascular ...
