LSC - 2019 - Azithromycin modulates viral-induced asthma exacerbation by targeting the innate immune response

In this study, OVA-sensitized/challenged mice were treated with AZM after inoculation with RSV. We found that AZM treatment not only suppressed AHR, but also reduced all key markers of exacerbation. Furthermore, TNFa-produced by alveolar macrophages was reduced with AZM treatment. Recombinant TNFa administration could reverse exacerbation in the presence of AZM. Our findings highlight the mechanism of AZM suppressed AHR and airway inflammation in RSV-induced asthma exacerbation through targeting the innate immune response linked to alveolar macrophages and TNFa production.
