摘要
程序性死亡配体-1(PD-L1)以细胞膜型PD-L1和可溶性PD-L1两种形式在NSCLC中高表达,通过与其受体结合参与肿瘤免疫逃逸。目前PD-L1抑制剂已进入NSCLC的Ⅰ期临床试验并反应良好,其治疗敏感性与肿瘤组织PD-L1的表达状态显著相关,因而PD-L1有望成为预测其药物疗效的生物学标志物。
Programmed deathligand 1 (PD-L1), which is highly expressed in NSCLC, can be divided into two categories: membrane PD-L1 and soluble PD-L1. PD-L1 participates in tumor immune escape through combining with its receptor. PD-L1 immune checkpoint inhibitors have entered the phase Ⅰ studies and showed a good application prospect. It is also found that the sensitivity of PD-L1 immune checkpoint inhibitors is strongly associated with the expression of PD-L1 in tumor. Therefore, PD-L1 can be used as a biomarker to predict its curative effect.
