The landscape of CAR-engineered innate immune cells for cancer immunotherapy

Abstract

Chimeric antigen receptor (CAR) T cells have improved the cure rate and quality of life of patients with lymphoid malignancies but have yet to demonstrate clinical benefits in solid tumors. Thus, several CAR-engineering strategies are currently being explored to overcome the functional limitations and the high cost of CAR T cells. Key among these are CAR-engineered innate immune cells, such as natural killer (NK) cells, NK T (NKT) cells, γδ T cells and macrophages. In this Review, we discuss the potential and limitations of efforts to develop and use innate immune CAR-engineered cells for cancer immunotherapy.
