Abstract Utilizing enzyme cascades as a promising approach for targeted cancer therapies holds significant potential, yet its clinical effectiveness is substantially hindered by functional losses during delivery. Complex coacervation emerges an intriguing strategy designing nanoreactors. In this study, noteworthy achievement presented in the development of lactobionic acid‐modified tumor microenvironment (TME)‐responsive polyelectrolyte complex vesicles (HGS‐PCVs) based on bioinspired homopolypeptoids, which serve facile, intelligent, and highly efficient nanoreactor tunable glucose oxidase, hemoglobin, sorafenib (SRF) to hepatic cells. The TME‐responsive permeability HGS‐PCVs enables selective entry into their interior, triggering enzymatic cascade reaction within tumor. This intricate process generates toxic hydroxyl radicals while concurrently lowering pH. Consequently, pH shift enhances SRF release, effectively promoting ferroptosis apoptosis target Further, administration not only initiates immunogenic cell death but also plays crucial role inducing maturation dendritic cells lymph nodes. It stimulates adaptive T‐cell response, mechanism that contributes impeding growth distant tumors vivo, demonstrating potential PCVs immunotherapy.

Breast cancer utilizes diverse immunosuppressive mechanisms to evade immune surveillance, thereby impairing immunotherapeutic effects. In this work, a chimeric peptide functionalized immunostimulant (designated as aGlyR) is fabricated boost photodynamic immunotherapy through PD-L1 deglycosylation and CD47 inhibition. The photosensitizer protoporphyrin IX (PpIX) conjugated via hydrophilic PEG8 linker, yielding the Fmoc-K(PpIX)-PEG8-GFTATPPAPDSPQEP. This could self-assemble into nanomicelles capable of encapsulating inhibitor RRx-001, generating multifunctional aGlyR. vitro in vivo results indicate that therapy (PDT) aGlyR disrupt breast cells trigger immunogenic cell death (ICD), leading release tumor-associated antigens (TAAs) activation immunological cascades. Additionally, component degradation PD-L1, which restores T cell-mediated activity. Concurrently, RRx-001 blocks pathway, disrupting antiphagocytic signaling activating innate responses. synergistic immunomodulatory approach effectively reverses complex factors, significantly enhancing effects conventional treatments.

Abstract Immune evasion and metastasis are the leading causes of poor prognosis in triple‐negative breast cancer treatment. Since current standard immunotherapies have limited efficacy due to immunologically cold microenvironment, it is crucial explore new strategies sensitize anticancer immune response. In this study, found that incorporating β ‐lapachone‐based oxidation therapy with CUDC101‐initiated epigenetic regulation results synergistic antitumor effects potent activation. To co‐deliver these two hydrophobic drugs, IR783 cyanine structure serves as stabilizer form a nanoformulation based on small molecule self‐assembly. Such IR783‐stabilized nanodrugs can not only lead cell apoptosis through HDAC inhibition‐enhanced but also cooperatively induce immunogenic death promote pro‐inflammatory cytokine gene expression reshape immunosuppressive microenvironment. Besides, inhibit both primary distant tumor growth effectively by elevating systemic immunity. This study provides promising approach synergize modulation for safe efficient immunotherapy.
