MUC5AC and asthma: When both non-asthma smoker donors 23 and 11 were removed from analysis, MUC5AC gene expression level showed both significant response to RV-A16 infection (p = 0.016 and p = 0.004 for non-asthma and asthma groups respectively), and asthma-related differential viral response between the asthma and non-asthma groups (p = 0.047) (S2 Fig.).
