CD8A and supranuclear palsy, progressive, 1: CD8+ T cells numbers did not differ between the groups (t = 1.602, p = 0.122; Fig. 2E), however, we also observed a shift in the ratio between memory and naive CD8+ T cells (t = 7.667, p < 0.001, and t = 8.595, p < 0.001, respectively; Fig. 2F,G) in PSP patients.
