In vivo macrophage engineering for renal cancer therapy

Chimeric antigen receptor (CAR) macrophage therapy has shown promising activity in preclinical models of solid tumors. A platform that combines CAR technology with lipid nanoparticles for in vivo macrophage engineering is now shown to generate pro-inflammatory CAR macrophages with sustained tumoricidal activity as effective therapy against renal cell carcinoma.
