Quantitative immunohistochemical (IHC) detection of neurons (NeuN), activated myeloid cells (Iba1-positive), and activated astrocytes (GFAP-positive) at 7 dpi revealed decreases in numbers of NeuN+ cells, and increased GFAP+ and IBA1+ cells [Figs. S1(A)–S1(E) in the Supplementary Material], indicating injury to the hippocampus and inflammation in the region of the hippocampus, even during acute infection. This evidence concerns the gene RBFOX3 and infection.
