中文摘要

在最近发表于Cell的一项研究中,Johnson等人证明,通过工程化改造使CAR-T 细胞产生RN7SL1——一种激活病毒感受器RIG-I和MDA5的新型RNA佐剂——可改善CAR-T 细胞的内在功能,激活肿瘤浸润髓系细胞,并增强内源性肿瘤特异性T细胞应答,从而在多种小鼠模型中即使出现CAR抗原丢失也能改善肿瘤控制。

In a recent Cell publication, Johnson et al. demonstrate that engineering chimeric antigen receptor (CAR)-T cells to produce RN7SL1, a novel RNA adjuvant that activates the viral sensors RIG-I and MDA5, improves intrinsic CAR-T cell function, activates tumor-infiltrating myeloid cells, and enhances endogenous tumor-specific T cell responses, resulting in improved tumor control despite CAR antigen loss in multiple mouse models.
