Common cold coronavirus 229E increases ISG mRNA expression significantly more in ALI cultures from patients with CRSwNP by RT-qPCR. Fold changes were calculated by subtracting the measured fold change of the infected ALIs from the averaged mock values for nonCRS and CRSnp, respectively (A). ALI pooled cultures from 5 control donors without CRS and 5 donors with CRSwNP were infected with 229E (MOI = 5) in triplicate ALI cultures and ISG mRNA fold changes were measured at 48-, 96- and 144-hours post infection (hpi) (B). * = P < 0.05; ** = P < 0.01; *** = P < 0.001; and **** = P < 0.0001; ns = not significant.
