Immunosuppressive tumor microenvironment, insufficient migration, and reduced effector function of tumor-specific T cells are the main hurdles that hamper the efficacy of immunotherapy in treating solid tumors. In this study, we combined the strength of adoptive cell transfer (ACT) and pathogen-based cancer vaccine and developed an innovative strategy, Reenergized ACT (ReACT), to treat solid tumors. ReACT uses a pathogen not only to break the immunosuppression, but also to drive the expansion and migration of tumor-specific T cells to the site of the tumor. With this combinatorial approach, we have demonstrated that ReACT enhances antitumor efficacy in comparison with either ACT or pathogen-based cancer vaccine alone in primary tumor eradication and offers long-term protection against reoccurrence in preclinical cancer models.
