The present invention provides an engineered immune cell targeting BCMA and use thereof. In particular, the present invention provides a CAR specifically targeting BCMA, the CAR comprising an antigen-binding domain which is an S-derived scFv, an antibody heavy chain variable region as shown in SEQ ID NO: 9 and an antibody light chain variable region as shown in SEQ ID NO: 10. The present invention also provides a CAR-T cell comprising the CAR, a double CAR- and CAR-T cell comprising the S-derived scFv, and related use thereof. Compared to CAR-T cells constructed using other scFvs, the constructed CAR-T cell of the present invention has a better killing effect and tumor elimination capability. |
