Cuproptosis is a novel copper-dependent programmed cell death. The efficacy of cuproptosis highly dependent on intracellular copper accumulation and counteracted by high level glutathione (GSH) in tumor cells. Here, this work develops self-amplified nanoparticles (Cel-Cu NP) using celastrol (Cel), natural product isolated from medical plant. In Cel-Cu NP, Cel serves as versatile ionophore, exhibiting an ideal coordination capacity toward ions without compromising the induction. Notably, can simultaneously scavenge GSH content to amplify cuproptosis. Moreover, further activates immunogenic death (ICD) elicit robust immune response. Combining with checkpoint blockade, NP effectively eradicates metastatic tumors mouse lung metastasis model. This study provides efficient nanomedicine inducing for immunotherapy.

Abstract Surgical resection remains the mainstream treatment for malignant melanoma. However, challenges in wound healing and residual tumor metastasis pose significant hurdles, resulting high recurrence rates patients. Herein, a bioactive injectable hydrogel (BG‐Mn gel ) formed by crosslinking sodium alginate (SA) with manganese‐doped glass (BG‐Mn) is developed as versatile platform anti‐tumor immunotherapy postoperative The incorporation of Mn 2+ within (BG) can activate cGAS‐STING immune pathway to elicit robust response cancer immunotherapy. Furthermore, doping BG endows system excellent photothermal properties, hence facilitating STING activation reversing immune‐suppressive microenvironment. exhibits favorable angiogenic capacity tissue regenerative potential, promotes cell migration vitro. When combining BG‐Mn anti‐PD‐1 antibody (α‐PD‐1) melanoma, it shows enhanced long‐term memory response. Remarkably, upregulate expression genes related blood vessel formation promote skin regeneration when treating full‐thickness wounds. Overall, Gel serves an effective adjuvant therapy regulate
