At a dose of 1 × 102 pfu/eye, 10 of 10 IFNαβR−/− mice infected with the LAT-plus virus survived infection (100% survival), while 0 of 10 IFNαβR−/− mice infected with the LAT-minus virus survived infection (0% survival) (Table 1, 1 × 102, p < 0.0001, Chi-square). Here, IFNAR2 is linked to infection.
