Sci Trans Med: 科学家鉴定出免疫检查点阻断治疗反应和抵抗的标志物

2017-03-05 zhangchengli MedSci原创

免疫检查点阻断代表了晚期黑色素瘤治疗的重大进步。然而,仅有少部分人经过细胞毒性T淋巴细胞相关抗原4(CTLA-4)或者程序性死亡受体1(PD-1)单药阻断后,具有持久的临床反应。尽管CTLA-4和PD-1抑制剂联合给药,反应率更高,然而毒性也显着增高。免疫检查点阻断已经在很多病人中产生了临床益处,然而仍然需要更好的能反映治疗反应的生物标志物,治疗抵抗的机制也不完全清楚。因此,为了改善患者的处理和预

免疫检查点阻断代表了晚期黑色素瘤治疗的重大进步。然而,仅有少部分人经过细胞毒性T淋巴细胞相关抗原4(CTLA-4)或者程序性死亡受体1(PD-1)单药阻断后,具有持久的临床反应。尽管CTLA-4和PD-1抑制剂联合给药,反应率更高,然而毒性也显着增高。免疫检查点阻断已经在很多病人中产生了临床益处,然而仍然需要更好的能反映治疗反应的生物标志物,治疗抵抗的机制也不完全清楚。因此,为了改善患者的处理和预后,临床上迫切需要预测免疫治疗的获益人群、了解免疫治疗抵抗的机制。

近期,一项发表在Science子刊Science Translational Medicine的文章通过研究一个相继经过CTLA-4和PD-1阻断治疗的黑色素瘤患者队列,鉴定出了免疫检查点阻断治疗反应和抵抗的标志物。

作者对同一队列的样本进行了分子谱深度分析,包括全外显子测序(WES)和T细胞受体测序(TCR-seq),结果表明更高的T细胞库克隆性,PD-1阻断剂治疗反应好,而T细胞库克隆性与CTLA-4阻断剂治疗反应无关。拷贝数变化(CNAs)的分析显示,对CTLA-4和PD-1阻断剂不反应的患者基因拷贝数丢失更严重,免疫通路相关基因表达降低。突变负荷和拷贝数丢失对治疗反应的影响是非冗余的,这表明了组合生物标志物在检查点阻断治疗中的潜在效用。
