摘要:
The present invention provides an anti-B7-H3 monoclonal antibody and use thereof in cell therapy. Specifically, the present invention provides an scFv, an antibody, and a specific CAR-T cell specifically targeting B7-H3. The present invention further provides an engineered immune cell capable of co-expressing a CAR targeting B7-H3 and a chimeric molecule or a secreted protein of PD-L1, the engineered immune cell having good tumor killing effects.
