Common cold coronavirus 229E clears faster in ALI cultures from patients with CRSwNP. ALI pooled cultures from 3 control donors without CRS and 3 donors with CRSwNP were infected with 229E (MOI = 5) in triplicate ALI cultures and viral titers were measured at 48-, 96- and 144-hours post infection (hpi) (A). In a second infection, ALI pooled cultures from 5 different control donors without CRS and 5 different donors with CRSwNP were infected with 229E (MOI = 5) again in triplicate ALI cultures (B). * = P < 0.05; ** = P < 0.01; *** = P < 0.001.
