Hepatocellular carcinoma (HCC) resistant to both chemotherapy and immunotherapy is among the deadliest malignancies. Doxorubicin widely used in transarterial HCC can induce immunogenic cell death (ICD), but resulting immunogenicity still weak. We aim seek a strategy for improving efficacy of ICD based on an immunoregulatory drug called icaritin. Icaritin induced mitophagy apoptosis provoke mouse Hepa1-6 human Huh7 cells. A combination icaritin doxorubicin with molar ratio 1:2 played synergistic role induction. The poly lactic-co-glycolic acid (PLGA)-polyethylene glycol (PEG)-aminoethyl anisamide (AEAA) nanoparticle (NP) targeted codelivery remodeled immunosuppressive tumor microenvironment triggered robust immune memory response, which efficiently improved anti-HCC effect at early stage model. In addition, combo PLGA-PEG-AEAA NP together lenvatinib significantly prolonged survival time mice advanced HCC. Collectively, our findings reveal mechanism provide effective immune-based therapeutic
