文摘免疫检查点抑制剂(immune checkpoint inhibitor,ICI)治疗是近年来备受瞩目的新型恶性肿瘤治疗方式,在癌症治疗史上具有里程碑式意义[1]。ICI是除手术、放化疗、分子靶向治疗后又一种能够改善患者生存及预后的治疗手段。ICI治疗已经获得FDA批准,在黑色素瘤、非小细胞肺癌、肾癌、尿路上皮癌中都证实有较好的客观反应率与更高的生存期[2-3]。因此,ICI被逐渐应用于更多的恶性肿瘤治疗[4-6]。程序性死亡蛋白配体1(programmed death ligand,PD-1)抑制剂是ICI药物中的一种,主要通过与PD-1受体作用,募集蛋白酪氨酸磷酸酶SHP-2,阻断肿瘤细胞负向调控机制,恢复免疫系统对肿瘤细胞的杀灭作用[8]。然而,PD-1抑制剂治疗在给患者带来获益的同时也可通过免疫细胞进入正常组织,从而引发自身免疫毒性[9]。其作用机制主要是由于体内PD-1受体分布广泛,PD-1在激活的效应T细胞、调节性T细胞、B细胞、单核细胞、未成熟的朗格汉斯细胞和天然杀伤T细胞表面均可表达,该信号通路受阻可影响全身各器官免疫应答。
