Title:
CHIMERIC ANTIGEN RECEPTOR CELLS TARGETING ROBO1, PREPARATION AND APPLICATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2018/218710
Kind Code:
A1
Abstract:
Provided are 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 bloc PD-1/PD-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.
