Research on viral-induced asthma exacerbation used a human mucociliary airway epithelium model to simulate rhinovirus infection, demonstrating IL-13-induced asthma responses and identifying CXCR2 antagonist MK-7123 as effective in reducing neutrophil migration, suggesting potential for testing immunomodulatory therapies [175]. The gene discussed is CXCR2; the disease is asthma.
