Abstract

CTL cells. Compared with the control group, combined treatment significantly up-regulated the secretion of immune-stimulatory cytokines, such as IFN-γ and TNF-α, and down-regulated the secretion of the immunosuppressive cytokine IL-10. Furthermore, the co-induction promoted the early activation of DC-CIK cells. These results indicated the co-induction with anti-PD-1 plus anti-CTLA-4 antibodies improved antitumor effects of DC-CIK cells by promoting proliferation, differentiation, and early activation and regulating the secretion of immune-stimulatory and suppressive cytokines in renal carcinoma cell lines.
