Key Mechanisms of Airway Relaxation in Asthma Revealed in New Study
Many therapeutics for asthma and other obstructive lung diseases target the β2-adrenergic receptor (β2AR), a G protein-coupled receptor (GPCR) that rapidly supports airway relaxation when stimulated. Yet, overuse of these agents is associated with adverse health outcomes, including death, which has limited their utility as frontline therapies. Now, a mouse model study published in today’s issue of Molecular Cell, from investigators at University Hospitals (UH) and Case Western Reserve University, identifies a novel strategy to isolate the beneficial effects of β2AR stimulation. This suggests a new therapeutic approach to airway diseases as well as numerous other conditions involving the aberrant function of GPCRs.
