Prodrug‐Based Versatile Nanomedicine for Enhancing Cancer Immunotherapy by Increasing Immunogenic Cell Death

Nanoparticle‐based tumor immunotherapy has emerged to show great potential for simultaneously regulating the immunosuppressive tumor microenvironment, reducing the unpleasant side effects, and activating tumor immunity. Herein, an excipient‐free glutathione/pH dual‐responsive prodrug nanoplatform is reported for immunotherapy, simply by sequentially liberating 5‐aminolevulinic acid and immunogenically inducing doxorubicin drug molecules, which...
