The structures and conjectures of special CARs (double scFvs). Construction of a TanCAR based on the (A) second-generation CAR, (B) third-generation CAR, (C) fourth-generation CAR (the intracellular domain contains a costimulatory molecule), and (D) fourth-generation CAR (the intracellular domain contains two costimulatory molecules). (E) Construction of the dual-signaling CARs based on the second-generation CAR.
