ADRs (Adrenergic Receptors) are expressed on virtually every cell type in the body and are the receptors for Adrenaline, Epinephrine and Norepinephrine within the Sympathetic Nervous System. They serve critical roles in maintaining homeostasis in normal physiologic settings as well as pathologic states. These receptors are also targets for therapeutically administered agonists and antagonists (Ref.1). ADRs are members of the super family of cell surface receptors that carry out signaling via GPCR (G-Protein Coupled Receptors) an...
