Betaadrenerge
Betaadrenerge refers to the beta-adrenergic system, including the beta-adrenergic receptors and their ligands, which mediate part of the sympathetic nervous system response. The term encompasses endogenous catecholamines like epinephrine and norepinephrine as well as synthetic agents that stimulate or block these receptors.
The beta-adrenergic receptor family comprises three main subtypes: β1, β2, and β3. β1 receptors are mainly in
All beta receptors are G protein-coupled receptors that typically couple to Gs proteins, stimulating adenylate cyclase
Pharmacologically, beta-adrenergic agents include endogenous agonists (epinephrine, norepinephrine) and synthetic drugs such as isoproterenol (non-selective β agonist)
