Because our results thus far indicate that IFNAR2 is important for anti-viral immunity to IAV, we next sought to determine whether the increased IAV-susceptibility of Ifnar2−/− mice affected their BSI susceptibility, and whether Ifnar2−/− mice exhibit a similar pattern of BSI susceptibility as Ifnar1−/− mice. Here, IFNAR1 is linked to bathing suit ichthyosis.
