嵌合抗原受体(CAR)T细胞治疗在血液系统恶性肿瘤中取得了显著的成功,但在实体瘤中仍然无效,部分原因是CAR T细胞在实体瘤微环境中的耗尽。为了研究胰腺癌中介孔蛋白重定向的CAR T细胞的功能障碍,我们建立了一个稳健的持续抗原暴露模型,该模型概括了T细胞耗竭的特征,并在体外和CAR T细胞患者中发现,CAR功能失调与CD8+T细胞向NK样T细胞的转变有关。此外,我们确定了一个定义CAR和TCR异常调节和转录因子的基因特征,包括SOX4和ID3作为CAR T细胞耗竭的关键调节因子。我们的发现揭示了人类CAR T细胞的可塑性,并证明了ID3和Sox4基因表达的下调可以通过预防或延缓CAR T细胞功能障碍来提高CAR T细胞治疗实体瘤的疗效。
Chimeric antigen receptor (CAR) T cell therapy has achieved remarkable success in hematological malignancies but remains ineffective in solid tumors, due in part to CAR T cell exhaustion in the solid tumor microenvironment. To study dysfunction of mesothelin-redirected CAR T cells in pancreatic cancer, we establish a robust model of continuous antigen exposure that recapitulates hallmark features of T cell exhaustion and discover, both in vitro and in CAR T cell patients, that CAR-dysregulation is associated with a CD8+ T-to-NK-like-T cell transition. Furthermore, we identify a gene signature defining CAR and TCR dysregulation and transcription factors, including SOX4 and ID3 as key regulators of CAR T cell exhaustion. Our findings shed light on the plasticity of human CAR T cells and demonstrate that genetic downmodulation of ID3 and SOX4 expression can improve the efficacy of CAR T cell therapy in solid tumors by preventing or delaying CAR T cell dysfunction.
