Irreversible electroporation combined with checkpoint blockade stimulates antitumor immune response in a hepatocellular carcinoma mouse model

Figure 2 The irreversible electroporation combined programmed cell death protein 1 antibody markedly altered the levels of Th1 cytokines in peripheral blood. A: Plasma levels of interleukin-2; B: Plasma levels of tumor necrosis factor-β; C: Plasma levels of interferon-γ. Values are expressed as means ± SED. ^aP < 0.05. ^bP < 0.01. ^cP < 0.001. IL-2: Interleukin-2; TNF-β: Tumor necrosis factor-β; INF-γ: Interferon-γ; IRE: Irreversible electroporation; PD-1: Programmed cell death protein 1.
