To comprehensively investigate the effect of TMEV infection on cell proliferation dynamics during the acute infection period (3–14 dpi), we conducted an analysis of KI-67+ cells in hippocampal slices from TMEV-infected mice at distinct time points: 3 dpi (n = 4), 7 dpi (n = 13), 14 dpi (n = 16; Table 1 and Figure 1). This evidence concerns the gene MKI67 and infection.
