Why the study?
Rhinoviruses trigger many acute asthma exacerbations, induce airway hyperresponsiveness, and decrease the efficacy of current symptom-relief therapeutics.
Does Rhinovirus C15 attenuate agonist-induced bronchodilation and cAMP production in human airway models?
Population
hPCLSs, primary HAECs, and HASM cells
Comparison
RV-C15 or RV-C15-conditioned HAEC media exposure vs unexposed controls

May blunt bronchodilator response during RV-C15 asthma exacerbations; leaves open whether targeting RV-C15 alters clinical outcomes.
Does Rhinovirus C15 attenuate agonist-induced bronchodilation and cAMP production in human airway models?
Rhinovirus C15 attenuates beta-2-adrenergic receptor-mediated airway relaxation and cAMP production independently of viral replication, suggesting a mechanism for decreased bronchodilator efficacy during asthma exacerbations.
Gebski et al. (2023) studied this question.
