Interestingly, infection with LGTV had no effects on dendritic spine numbers of CA1 and DG hippocampal subregions in Irf-7−/− mice (Fig. 9a–d) (CA1: apical: F (2, 95) = 1.44, p = 0.24, basal: F (2, 84) = 0.67, p = 0.51; DG: superior: F (2, 91) = 0.94, p = 0.22, inferior: F (2, 88) = 0.57, p = 0.56). The gene discussed is IRF7; the disease is infection.
