Directly delivering therapeutic proteins to their intracellular targets remains a great challenge. Here, we apply CD8+ T cells to form pores on the tumor cells' plasma membranes, enabling perfusion of ribonuclease A (RNase A) and granzyme B into cells, therefore effectively inducing tumor apoptosis and pyroptosis by activating caspase 3 and gasdermin E pathways to potentiate the CD8+ T cell-mediated immunotherapy. Then, RNase A, programmed cell death ligand 1 antibody, and a photothermal agent were further loaded into an injectable hydrogel to treat the low immunogenic murine breast cancer. Notably, three courses of laser irradiation induced efficient cell apoptosis and immune activation, resulting in a notable therapeutic efficacy that 75% of the tumors were ablated without relapse.
