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

Figure 4 Irreversible electroporation combined programmed cell death protein 1 treatment modulated the concentrations of T helper type 1 cytokines in the peripheral blood. A: Plasma concentration of interleukin-2; B: Plasma concentration of tumor necrosis factor-β; C: Plasma concentration of interferon-γ (values represent mean ± standard deviation, ^aP < 0.05, ^bP < 0.01, ^cP < 0.001). IL-2: Interleukin-2; INF-γ: Interferon-γ; IRE: Irreversible electroporation; PD-1: Programmed cell death protein 1; TNF-β: Tumor necrosis factor-β.
