Fig 1: Characterization of lymphocytes within the cornu ammonis (A) and dentate gyrus (B) at different time points after tamoxifen-induced neurodegeneration (TAM, T) versus healthy control mice (Ctrl, C). t1, 1 week; t2, 10 weeks; t3, 10 months after primary encephalitis induction. Data from 4 to 12 mice/group and time point presented as mean ± SD. Statistical analysis performed in Prism 10.1.0 using Kruskal–Wallis and pairwise comparisons post-hoc uncorrected Dunn’s test. (C) Representative images of hippocampal CD8 T cell infiltration 40 weeks after primary encephalitis onset.
