ABSTRACT
Chimeric antigen receptor (CAR)-engineered adoptive cell therapy marks a revolution in cancer treatment based on the highly successful responses to CAR T cell therapy in the treatment of blood cancers. Due to the versatile structure of CARs, this technology can be easily adapted to other immune cell types, including macrophages and NKs, and applied in the treatment of many other cancers. However, high costs and fatal adverse effects represent significant concerns for future development. In vitro transcribed (IVT) mRNA therapeutics, which possess a high safety profile and straightforward production methods, could provide a useful alternative for CAR cell construction. However, the low stability and transfection efficiency of IVT-mRNA in immune cells limit further applications. In this work, we successfully engineered CAR macrophages (CAR-Ms) and CAR T cells with CAR mRNA using lipid nanoparticles (LNPs). Both the LNP formulations and mRNA modifications were optimized for in vitro mRNA transfection. More importantly, the CAR macrophages and CAR T cells both demonstrated significant cytotoxic effects on B lymphoma in vitro, underscoring the great potential of mRNA-engineered adoptive cell therapy.
