Abstract:
Current cancer immunotherapies are often limited by suboptimal efficacy and significant adverse effects. Strategies centered on immunogenic cell death (ICD) offer promising solution, yet monotherapies frequently fail to achieve complete tumor eradication. To address this, we developed an alginate-based hydrogel system (SA-NLG-NA-DOX) for the co-delivery of an immunomodulator, a tumor vaccine, and the chemotherapeutic drug doxorubicin. This platform enabled sustained drug release and elicited potent, broad-spectrum cytotoxicity against multiple tumor cell lines. Furthermore, it robustly activated dendritic cells, enhancing their phagocytic capacity and stimulating the secretion of key inflammatory cytokines. The underlying immune activation was mechanistically linked to the cGAS-STING and TLR-MyD88 pathways. Collectively, SA-NLG-NA-DOX represents a novel and translatable chemo-immunotherapy platform with significant potential for improved cancer treatment.
