摘要:
The present invention relates to chimeric antigen receptor cells targeting ROBO1, in particular, enhanced CAR-T cells and CAR-NK cells targeting ROBO1, and preparation and application thereof. The cells can stably expressing CAR elements, while secreting extracellular domain molecules expressing PD-1 protein or mutants thereof, and thus may block PD- 11PD-L1 molecular interaction. It has been found through animal experiments that the cells have very good anti-tumor effects, and the above-mentioned cells can significantly reduce tumor recurrence and improve the survival rate compared with the conventional ROBO1-targeted CAR modified cells.
