Radiofrequency ablation (RFA), a critical therapy for hepatocellular carcinoma (HCC), carries significant risk of recurrence and metastasis, particularly owing to mechanisms involving immune evasion antigen downregulation via epigenetic modifications. This study introduces "nano-epidrug" named MFMP. MFMP, which is composed hollow mesoporous manganese dioxide (MnO2) nanoparticles, FIDAS-5 as an MAT2A inhibitor, macrophage membrane, anti-PD-L1 (aPD-L1), targets HCC cells. By selectively binding these cells, MFMP initially reverses suppression PD-L1 inhibition. After endocytosis, disassembles in the tumor microenvironment, releasing Mn2+. prevents cGAS methylation, whereas Mn2+ aids STING pathway restoration. In addition, reduces m6A RNA modification, suppressing EGFR expression. These changes enhance antigenicity promote cytotoxic T cell recognition killing. Furthermore, mediates immunogenic death by synergizing with RFA through DNA demethylation, mRNA TBK1 protein phosphorylation, thereby inhibiting metastasis enhancing memory. Thus, potential adjunctive requiring clinical validation.
