Although tGFP signal is visible in the dentate gyrus (Figure 5), only a few cells co-localized visually with DCX, and quantitative co-localization analysis indicated low overlap (Supplementary Fig. 5, r = 0.177, M1 = 0.073, M2 = 0.597) suggesting that infection in this area primarily affected mature neurons nearby rather than immature neurons. Here, DCX is linked to infection.
