Irreversible electroporation combined with anti-programmed cell death protein 1 therapy promotes tumor antigen-specific CD8+ T cell response

Figure 3 Irreversible electroporation combined with anti-programmed cell death protein 1 treatment increased peripheral blood cell infiltration of natural killer and B cells. A: Percentages of natural killer cells; B: Percentages of B cells (values represent mean ± standard deviation, ^aP < 0.05, ^bP < 0.01, ^cP < 0.001). IRE: Irreversible electroporation; NK: Natural killer; PD-1: Programmed cell death protein 1.
