Quantification of Beta Adrenergic Receptor Subtypes in Beta-Arrestin Knockout Mouse Airways

In allergic asthma Beta 2 adrenergic receptors (β2ARs) are important mediators of bronchorelaxation and, paradoxically, asthma development. This contradiction is likely due to the activation of dual signaling pathways that are downstream of G proteins or β-arrestins. Our group has recently shown that β-arrestin-2 acts in its classical role to desensitize and constrain β2AR-induced relaxation of...

Differential cardioprotective/cardiotoxic effects mediated by beta-adrenergic receptor subtypes.

Recent data suggest that beta-adrenergic receptor subtypes couple differentially to signaling pathways regulating cardiac function vs. cardiac remodeling. To dissect the roles of beta1- vs. beta2-receptors in the pathogenesis of cardiomyopathy, doxorubicin was administered to beta1, beta2, and beta1/beta2 knockout (-/-) and wild-type mice. Expression and activation of MAPKs were measured. Wild-...

Beta-2 adrenergic receptor

The beta-2 adrenergic receptor (β2 adrenoreceptor), also known as ADRB2, is a cell membrane-spanning beta-adrenergic receptor that interacts with (binds) epinephrine, a hormone and neurotransmitter (ligand synonym, adrenaline) whose signaling, via a downstream Ltype calcium channel interaction, mediates physiologic responses such as smooth muscle relaxation and bronchodilation. Unlike other adr...

Received for publication 12 August 1980 and in revised form 23 March 1981. group to include agonist binding, receptor-adenylate cyclase coupling, intrinsic adenylate cyclase activity, and catecholamine metabolism may help determine the basic cause of beta adrenergic hyporesponsiveness in both CFH and CF.

Beta-adrenergic function in airways of healthy and asthmatic subjects.

We measured the short-term effects of beta-adrenergic blockade with propranolol (0.2 mg/kg iv), followed by stimulation with salbutamol (200 mug inhaled), on specific airway conductance (SGaw) heart rate, and systemic blood pressure (BP) in 11 healthy subjects, and 11 symptom-free asthmatics with normal lung function values. Propranolol induced a significant bronchoconstrictor effect in both gr...
