Biologically reprogrammed macrophage-tumor chimeric exosomes were constructed by introducing tumor nuclei into activated macrophages (aMT-exos). This strategy generated exosomes with tumor components as well as classical activated macrophage (M1) properties, including tumor-antigen-MHC molecules, co-stimulatory molecules, immune-activated cytokines and other tumor components [101].Back to article page
