IFNB1 and infection: Quantified scores of IFN-α and IFN-β staining intensity were significantly lower in asthmatic patients at baseline (P = .035 and .002) and day 4 after infection (P = .002 for both; Fig 1, F and G) and IFN-β scores were also lower at week 6 (P = .002; Fig 1, G) compared with the same time points in control subjects.
