Abstract
While being a safe and effective precision therapy strategy, tumor immunotherapy still fails in many patients due to the immunosuppressive tumor microenvironment. Emerging evidence has indicated that the targeted nano-drug delivery systems can accurately deliver therapeutic agents to potentiate the efficacy of immunotherapy. This review will outline recent advances in applying targeted nano-drug delivery systems in immunotherapy, with an emphasis on their crucial roles in regulating innate immune responses, adaptive immune responses, and immunogenic cell death. We will also discuss the current challenges and future opportunities for the clinical translation of targeted nano-drug delivery systems for tumor immunotherapy.
