This treatment downregulated the immunosuppressive cytokines IL-10 and TGF-β, decreased regulatory T cell (Treg) infiltration, promoted M1-like polarization of tumor-associated macrophages, and enhanced CD8+ T cell infiltration and cytotoxicity in ENZR prostate tumors, thereby reprogramming the tumor immune microenvironment. The gene discussed is CD8A; the disease is prostate neoplasm.
