By synergizing the ICD effect of Cur and the PD1/PDL1 axis blocking function of genetically engineered NVs, the PD1@Cur-PLGA enhanced the intratumoral infiltration rate of mature dendritic cells and CD8+ T cells in tumor tissues, resulting in significantly inhibiting tumor growth in breast and prostate tumor-bearing mouse models. The gene discussed is CD8A; the disease is neoplasm.
