Immune checkpoint blockade (ICB) has revolutionized cancer therapy, but varying response rates illustrate the need for biomarkers of response. Studies in mice have identified a subset of CD8 T cells that is essential for response to PD‐1 ICB. These CD8 T cells co‐express CXCR5, PD‐1 and Tcf1, and provide effector T cells upon PD‐1 ICB. It is unknown whether similar T cells play a role in PD‐1 ICB in humans.

健康个体和血液系统恶性肿瘤患者的人 CXCR5+PD-1+ CD8 T 细胞

免疫检查点阻断 (ICB) 彻底改变了癌症治疗,但不同的反应率表明需要反应生物标志物。小鼠研究已经确定了对 PD-1 ICB 反应必不可少的 CD8 T 细胞亚群。这些 CD8 T 细胞共表达 CXCR5、PD-1 和 Tcf1,并在 PD-1 ICB 上提供效应 T 细胞。尚不清楚类似的 T 细胞是否在人类的 PD-1 ICB 中起作用。
