phenotype observed in females
phenotype observed in males
N normal phenotype
mortality/aging
• infection of mice with VSV or mouse-adapted influenza induces greater lethality than in similarly treated wild-type mice

immune system
N
• mice exhibit normal immune systems in the absence of viral infection
• mouse embryonic fibroblasts infected with vesicular stomatitis virus (VSV) exhibit increased apoptosis and viral replication compared to similarly treated wild-type cells (J:63671)
• infection of mice with VSV induces respiratory distress, paralytic disease, and premature lethality unlike in wild-type mice (J:63671)
• however, pre-treatment with IFNalpha/beta or gamma restores protection against virally induced apoptosis (J:63671)
• mouse embryonic fibroblasts exhibit increased susceptibility to RNA virus replication compared with wild-type cells (J:167126)
• mice infected with mouse-adapted influenza exhibit increased apoptosis in the lungs and lethality compared with similarly treated wild-type mice
• replication of mouse-adapted influenza in mouse embryonic fibroblasts is increased compared to in similarly treated wild-type mice

cellular
• mouse embryonic fibroblasts are resistant to double-strand RNA-induced apoptosis unlike wild-type cells
• mouse embryonic fibroblasts infected with vesicular stomatitis virus exhibit increased apoptosis compared to similarly treated wild-type cells
• however, pre-treatment with IFNalpha/beta or gamma restores protection against virally induced apoptosis
