When T cell recruitment was blocked by FTY720 treatment starting on day 12 post tumor implantation, the TCF1+PD-1int subset of LSD1-deficient CD8+ TILs appeared to be preferentially decreased to a level comparable to that of the WT counterpart in the next 10 days, while expectedly giving rise to numerically more TCF1-PD-1hi cells than the WT counterpart (Supplementary Fig. 6a–c). This evidence concerns the gene CD8A and neoplasm.
