Abstract The induction of cuproptosis, a recently identified form copper‐dependent immunogenic cell death, is promising approach for antitumor therapy. However, sufficient accumulation intracellular copper ions (Cu 2+ ) in tumor cells essential inducing cuproptosis. Herein, an intelligent cuproptosis‐inducing nanosystem constructed by encapsulating oxide (CuO) nanoparticles with the ionophore elesclomol (ES). After uptake cells, ES@CuO degraded to release Cu and ES synergistically trigger thereby significantly inhibiting growth murine B16 melanoma cells. Moreover, further promoted cuproptosis‐mediated immune responses reprogrammed immunosuppressive microenvironment increasing number tumor‐infiltrating lymphocytes secreted inflammatory cytokines.

Abstract Autophagy, a lysosome‐involved degradation pathway, as self‐protective cellular process, always weakens the efficiency of tumor therapies. Herein, for first time, biodegradable copper (Cu) ions doped layered double hydroxide (Cu‐LDH) nanoparticles are reported cancer immunotherapy via lysosomal rupture‐mediated “Broken Window Effect”. Only injection Cu‐LDH single therapeutic agent achieves various organelles destruction after rupture, well abnormal aggregation Cu in cells cuproptosis and pyroptosis. More importantly, autophagy inhibition caused by rupture improves overload‐mediated pyroptosis blocking lysosome‐mediated bulk leading to good anti‐tumor immune responses ultimately high‐efficiency growth inhibition.

The designability and high reactivity of nanotechnology provide strategies for antitumor therapy by regulating the redox state in tumor cells. Here, we synthesize a kind vanadium dioxide nanoparticle encapsulated bovine serum albumin containing disulfide bonds (VSB NPs) photothermal-enhanced ferroptosis pyroptosis effects. Mechanism studies show that can effectively consume overexpressed glutathione (GSH) microenvironment, leading to decrease peroxidase 4 (GPX4) activity. Simultaneously, tetravalent induce catalytic reaction H2O2, producing plenty toxic hydroxyl radicals (·OH) singlet oxygen (1O2), cell ferroptosis. In addition, consumption also lead degradation nanoparticles into high-valent vanadates, activating thermal protein domain-associated 3 (NLRP3) inflammasomes causing pyroptosis.
