Abstract Cancer immunotherapy has demonstrated significant efficacy in various tumors, but its effectiveness treating Hepatocellular Carcinoma (HCC) remains limited. Therefore, there is an urgent need to identify a new target and develop corresponding intervention strategies. Bioinformatics analysis revealed that growth differentiation factor 15 (GDF15) highly expressed HCC closely related poor prognosis of patients. The previous study GDF15 can promote immunosuppression the tumor microenvironment. knocking out through gene editing could potentially reverse suppressive immune microenvironment permanently. To deliver CRISPR/Cas9 system specifically HCC, nanocapsules (SNC) coated with targeting peptides (SP94) on their surface utilized. These incorporate disulfide bonds (SNC SS ) release contents characterized by high levels glutathione (GSH). In vivo, SNC cells, exert marked inhibitory effect progression, immunotherapy. Mechanistically, CyTOF showed favorable changes immunocytes killer function increased inhibitive decreased. findings highlight potential CRISPR‐Cas9 modulating improving existing approaches for HCC.

Published: April 3, 2025

T cell-mediated cancer immunotherapy harnesses the power of cytotoxic lymphocytes (CTLs) to target and eradicate tumor cells. However, cells often evade immune attack through membrane repair mechanisms involving endosomal sorting complexes required for transport (ESCRT) suppression within microenvironment. Here, we developed a robust TMV@PpCHIL nanomedicine address these issues by reprogramming via in situ gene editing. Using CRISPR/Cas9, disrupted Chmp4b gene, key component ESCRT machinery, preventing from repairing CTL-induced damage. Simultaneously, genetically engineered produce interleukin-12 (IL-12), cytokine that enhances CTL activation. The nanomedicine, designed coating vesicles (TMVs) onto polyamidoamine (PAMAM) dendrimer-condensed plasmid complexes, ensured efficient CRISPR/Cas9-based editing sustained IL-12 production. This approach significantly enhanced CTL-mediated cell cytotoxicity, suppressed growth, reduced metastasis, prolonged survival, providing promising strategy durable treatment.
