Immunogenic PANoptosis‐Initiated Cancer Sono‐Immune Reediting Nanotherapy by Iteratively Boosting Cancer Immunity Cycle

The cancer‐immune cycle conceptualized the mechanisms of driving T cell responses to tumors, but w as limited by immunological ignorance elicited by tumor inherent immunoediting, which failed to initiate and maintain adaptive immunity. Targeting specific vulnerabilities of cell death patterns may provide unique opportunities to boost T cell antitumor immunological effects. Here an ultrasound nanomedicine‐triggered tumor immuno‐reediting therapeutic strategy using nano/genetically engineered extracellular vesicles, which can induce tumor highly immunogenic PANoptosis and iteratively start‐up the energization of cancer innate immunity cycle by repeatedly liberating damage‐associated molecular patterns, thereby priming sufficient antigen‐specific T cells and shaping protective immune response through activating cGAS‐STING signaling pathways, is reported. Aided by immune checkpoint blockade, the reprogramming of immune microenvironment further facilitated a prompt bridging of innate and adaptive immunity, and remarkably suppressed metastatic and rechallenged tumor growth. Thus, targeting PANoptotic cell death provides a catcher against immune escape and a positive‐feedback immune activation gateway for overcoming immune resistance to intractable cancers. A nano/genetically engineered sonosensitive extracellular vesicles are rationally designed for ultrasound nanomedicine‐triggered tumor immuno‐reediting therapeutic by efficiently inducing tumor immunogenic PANoptosis and iteratively boosting cancer innate immunity cycle. This specific regulated cell death renders tumor cells highly immunogenic through maximally activating damage‐associated molecular patterns, thereby reprogramming negative immune microenvironment and advancing positive adaptive antitumor immune response.
