Although we do not address viral bioaerosols in this review, Nawroth et al. (Ref 83) developed an airway lung-on-chip model to study viral-induced asthma exacerbations, demonstrating altered secretion of IL-6, IFN-λ1 and CXCL10 following IL-13 treatment and evaluating neutrophil migration and immunomodulatory therapy under asthmatic and healthy conditions (Ref 83). Here, IL13 is linked to asthma.
