In 2-month-old mice, infection with H7N7 IAV at day 8 post-infection resulted in an increase in CCL2 [Figure 2A, two-way ANOVA Finfection(1, 11) = 7.50, p = 0.02], IFNγ [Figure 2B, two-way ANOVA Finfection(1, 11) = 4.86, p = 0.04], IL1β [Figure 2C, two-way ANOVA Finfection(1, 10) = 6.84, p = 0.02], and IL-6 [Figure 2D, two-way ANOVA Finfection(1, 11) = 4.16, p = 0.06] in the lungs of unvaccinated mice compared to control mice inoculated with PBS (CCL2: p = 0.003, IFNγ: p = 0.01, IL1β: p = 0.01, IL-6: p = 0.04). Here, IFNG is linked to infection.
