摘要: CRISPR/Cas9基因编辑技术能有效解决嵌合抗原受体T细胞(CAR-T)疗法中T细胞来源不足的问题,并通过敲除T细胞活性抑制的相关基因,增强其肿瘤杀伤作用。此外,该技术还可用于构建具有双重靶向作用的T细胞,阻止肿瘤免疫逃逸,减少治疗后复发、耐药等情况的发生。相较于其他基因工程技术的复杂过程,CRISPR/Cas9具有便捷高效及多重基因组编辑的优点,对完善CAR-T治疗策略具有重要意义。

Abstract: CRISPR/Cas9 gene editing technology can effectively solve the problem of insufficient source of T cells in chimerical antigen receptor-T (CAR-T) therapy and enhance their anti-tumor abilities by knocking out the genes related to the suppression of T cells activity. The technology can also be used to construct T cells with dual-targeting effect to stop tumor immune escape and inhibit recurrence and drug resistance development during chemotherapy. Compared with the other genetic engineering technologies that have complex processes, multiple genome editing by CRISPR/Cas9 is a technology of efficient and convenient to operate.So it is believed to be valuable and potential target molecules for CAR-T therapy.

Key words: CAR-T cells, CRISPR/Cas9, immunotherapy
