Casirati等人和Wellhausen等人近期发表的两项研究报告,通过改变靶蛋白中的单个氨基酸,使CAR无法结合,同时不损害蛋白功能,从而对正常造血干/祖细胞(HSPC)进行基因工程改造,使其抵抗嵌合抗原受体(CAR)T细胞。这一策略可选择性靶向癌细胞,而不损伤正常造血细胞。
Two recent studies, by Casirati et al. and Wellhausen et al., report genetically engineering normal hematopoietic stem and progenitor cells (HSPCs) to be resistant to chimeric antigen receptor (CAR)-T cells, by changing a single amino acid in the target protein that abrogates CAR binding, without compromising protein function. This allows for selective targeting of cancer cells without harming normal hematopoietic cells.
