程序性死亡受体-1（PD-1），又名CD279，和程序性死亡配体-1（PD-L1）都是与免疫相关的蛋白。PD-1是分布在T细胞表面的一种免疫共抑制分子，其配体PD-L1表达于上皮细胞和内皮细胞，不同类型的免疫细胞，以及抗原递呈细胞（树突状细胞、巨噬细胞、B细胞）。PD-L1可分为组成型表达和炎症反应中干扰素上调型表达，如组织慢性感染的情况。在肿瘤和病毒感染时，细胞PD-L1表达上调，与T细胞表面的PD-1受体相互作用，能够抑制T细胞的活化、增殖及对肿瘤的杀伤，使其功能发生紊乱和枯竭。PD-1/PD-L1信号通路与肿瘤和病毒的免疫逃逸密切相关，是免疫治疗肿瘤和慢性传染病的重要新靶点。利用抗PD-1、PD-L1的单克隆抗体阻断PD-1/PD-L1信号通路，能够恢复T细胞的免疫杀伤功能。

PD-1，PD-L1与肿瘤治疗

当T细胞表面的PD-1与肿瘤细胞表面的PD-L1结合，则有利于细胞增殖、细胞因子的分泌以及肿瘤细胞的裂解。用单克隆抗体与PD-1和PD-L1结合的免疫治疗方法已取得初步成效[1]，包括恶性黑色素瘤、非小细胞肺癌、肾细胞癌和其他肿瘤类型[2]。然而，由于大多数组织依靠PD-L1的表达来限制T细胞应答，因此使用PD-L1和PD-1抗体来阻断PD-L1和PD-1需要解决外周耐受阻断的问题。

CRISPR和PD-1，PD-L1

CRISPR-Cas9系统是一种高效的基因编辑工具，经过引导RNA（sgRNA）引导，Cas9核算内切酶能够准确地靶向目的基因进行剪切，产生DNA双链切口(DSBs)，进而启动DNA修复程序，产生特定基因组修饰。该基因组编辑技术在2013第一次应用于哺乳动物细胞和动物，随之，基于CRISPR-Cas9的治疗方法在癌症建模和治疗研究中也快速建立起来了[3]。 CRISPR-Cas9系统可通过病毒或非病毒转导的方法直接应用于人类细胞[4]。敲除PD-1基因能够有效促进T细胞对肿瘤细胞的免疫杀伤力[5]。用Cas9-sgRNA和外源单链DNA模板替换靶核苷酸的方法可以成功敲除PD-1[6]，实验过程中T细胞表面PD-1敲除后，T细胞免疫应答增强，对癌细胞的杀伤力增大[7]。慢病毒CRISPR系统在Jurkat T细胞中的应用也促进了T细胞的功能研究[8]。

最近，NIH重组DNA咨询委员会批准了一项临床试验。在这个临床试验中，用CRISPR-Cas9的方法敲除了PD-1和NY-ESO-1受体，这是CRISPR-Cas9第一次在临床试验中得到应用[9]。类似的还有用CRISPR-Cas9敲除前列腺癌自体T细胞的PD-1(NCT02867345)，膀胱癌自体T细胞的PD-1(NCT02863913)，以及肾细胞癌自体T细胞的PD-1(NCT02867332)也在试验中。无论在体外水平还是动物模型中，用CRISPR基因编辑CAR T展现出强大的抗肿瘤活性[10]。肿瘤细胞表面的PD-L1会削弱CAR T细胞的功能，导致肿瘤细胞不能清除。用CRISPR/Cas9技术将抗CD19的CAR T细胞的PD-1敲除，在体外能够增强CAR T细胞对肿瘤细胞的杀伤能力，在体内移植肿瘤模型中能够增强CAR T细胞对肿瘤细胞的清除能力[11]。
