Analysis of GFAP fluorescent intensity in hippocampal subregions at day 10 post-infection showed that H7N7 infection resulted in a non-significant decrease in GFAP expression levels in the CA1 (Δ11%, p = 0.32, Figure 4D) and dentate gyrus subregion (Δ13%, p = 0.24, Figures 8E, F) of unvaccinated mice compared to PBS inoculated mice. The gene discussed is GFAP; the disease is infection.
