Effects of intranasal IAV infection of wild-type (WT) C57BL/6 mice, C57BL/6-congenic global 155-KO mice, or mice that have undergone reciprocal bone marrow transfer on bronchoalveolar lavage fluid levels of: (a) Interferon-γ (IFN-γ; ng/ml); (b) Interleukin-6 (IL-6; ng/ml); (c) p40 subunit of interleukin-12 (IL-12 [p40]; ng/ml); and (d) Keratinocyte cytokine/CXCL-1 (KC; ng/ml). n>5 per group. All data were analyzed by ANOVA with a post hoc Tukey-Kramer multiple comparison post-test and are presented as mean ± SEM. *P<0.05, **P<0.005, #P<0.001, vs. WSN-infected WT mice. †P<0.05, ¶P<0.001, vs. WSN-infected 155-KO mice.
