CD8+ T cells are the main effector cells involved in combination therapy with anti-PD-1 and anti-CD4 mAb. All mice receiving a cell-depleting anti-CD8 mAb in association with combined anti-PD-1/anti-CD4 mAb therapy, after i.v. challenge with Neuro2a-luc (panel a) or NXS2-luc (panel b) cells, develop tumors in a similar fashion as mice receiving no therapy but only irrelevant mAb. P values of combined anti-PD-1/anti-CD4 mAb therapy + anti-CD8 mAb vs combined therapy are indicated (Wilcoxon log-rank test). Percentages of progression-free mice are indicated on the Y-axis and the fraction of progression-free mice of each group is given in brackets. The schedule shown in the inset shows the timing of treatments.
