Co-expression of IL-7 reduces the apoptosis of NKG2D-CAR T cells. (a) After NKG2D-CAR and NKG2DIL7-CAR T cells were cocultured with PC-3 tumor cells for 7 days, the cells were stained with Annexin-V/7-AAD and the apoptosis was detected by FACS. The statistical analysis was shown in the right panel. (b) Flow cytometric analysis of Bcl-2 protein expression in CAR T cells 7 days after tumor cell stimulation. (c) The Bcl-2 expression in CD4+ and CD8+ CAR T cells was detected by FACS 7 days after tumor cell stimulation. ** p < 0.01. Data are representative of 4 donors and have been gated on NKG2D+ T cells.
