However, there are still some major challenges, including precise tumor targeting to avoid off-target or ＂on-target/off-tumor＂ toxicity, adequate T cell infiltration and migration to solid tumors and T cell proliferation and persistence across the physical and biochemical barriers of solid tumors. In this review, we focus on the primary challenges and strafegies to design safe and effective CAR T cells, including using novel cutting-edge technologies for CAR and vecfor designs to increase both the safety and efficacy, further T cell modification to overcome the tumorassociated immune suppression, and using gene editing technologies to generate universal CAR T cells. All these efforts promote the development and evolution of CAR T cell therapy and move toward our ultimate goal--curing cancer with high safety, high efficacy, and low cost.展开更多
