Gasdermin (GSDM)-mediated pyroptosis involves the induction of mitochondrial damage and subsequent release DNA (mtDNA), which is anticipated to activate cGAS-STING pathway, thereby augmenting antitumor immune response. However, challenges lie in effectively triggering cancer cells subsequently enhancing activation with specificity. Herein, we developed intelligent self-cascaded pyroptosis-STING initiators cobalt fluoride (CoF2) nanocatalysts for catalytic metalloimmunotherapy. CoF2 a semiconductor structure enzyme-like activity generated substantial amount reactive oxygen species (ROS) under stimulation by endogenous H2O2 exogenous ultrasound. Importantly, discovered that Co-based nanomaterials themselves induce cells. Therefore, initially acted as inducers, caspase-1/GSDMD-dependent via Co2+ ROS, leading mtDNA release. Subsequently, were further utilized STING agonists specifically capable detecting pathway. These cascade events triggered robust response, modulating immunosuppressive tumor microenvironment into an immune-supportive state, providing favorable support therapy. This innovative strategy not only significantly impeded growth primary but also elicited response augment efficacy checkpoint inhibitors preventing distant progression. Overall, this study proposed self-cascade activating amplifying pathway specificity mediated pyroptosis, representing valuable avenue future

Abstract Nanozyme‐mediated chemodynamic therapy has emerged as a promising strategy due to its tumor specificity and controlled catalytic activity. However, the poor efficacy caused by low hydrogen peroxide (H 2 O ) levels in microenvironment (TME) poses challenges. Herein, an H self‐supplying nanozyme is constructed through loading peroxide‐like active platinum nanoparticles (Pt NPs) on zinc (ZnO (denoted ZnO @Pt). releases response acidic TME. Pt NPs catalyze hydroxyl radical generation from while reducing mitigation of oxidative stress glutathione, serving reactive oxygen (ROS) amplifier self‐cascade catalysis. In addition, Zn 2+ released interferes with cell energy supply metabolism, enabling ion interference synergize therapy. vitro studies demonstrate that @Pt induces cellular injury enhanced ROS release, downregulating ATP NAD + levels. vivo assessment anticancer effects showed could generate at sites induce apoptosis downregulate pathways associated glycolysis, resulting 89.7% reduction growth.
