Methods: Here, we developed programmed cell death protein 1 (PD1)-overexpressing genetically engineered nanovesicles (NVs)-coated curcumin (Cur)-loaded poly (lactic-co-poly-polyglycolic acid) nanoparticles (PD1@Cur-PLGA) to integrate ICD and ICB therapy for enhancing tumor immunotherapy. This evidence concerns the gene PDCD1 and neoplasm.
