By binding to different surface proteins, this nanocomplex enhances the intracellular delivery of cargos and induces potent anticancer immune responses against melanoma cells.3 We have previously demonstrated that PD-1/PD-L1 blockade enhanced the efficacy of DC-based cancer immunotherapy.4,5 Moreover, the combination of nanomedicines and PD-L1 blockade has been reported to enhance CD8+ T cell activation and inhibit immunosuppressive cells within the tumor microenvironment.6 In the present study, we investigated the therapeutic efficacy of a combinatorial treatment comprising the immunoadjuvant nanocomplex PSPEI-PIC, a DC vaccine, and PD-L1 blockade in a murine colon cancer model. 关 键 词:ADJUVANT vaccines IMMUNOTHERAPY
