直到20世纪后期,人们发现T细胞发生免疫反应是有“开关”的,称免疫检查点(Immune checkpoint),可防止机体受到过度免疫的伤害,程序性死亡受体-1(programmed cell death protein-1,PD-1)就是其中一种。自2014年PD1/PDL1单抗面世以来,历经8年时间,免疫检查点抑制剂治疗彻底改革了肿瘤的治...
免疫检查点(immune checkpoints)是调节免疫系统的关键分子,它们通过控制免疫反应的强度和持续时间,维持...
通过靶向免疫抑制检查点受体——细胞毒性T淋巴细胞相关蛋白(CTLA4)或程序性死亡蛋白(PD1)及其配体(PDL1,PDL2),来抵抗肿瘤微环境的免疫抑制作用。 2.什么是免疫检查点(Immune Checkpoints)? 为了排除了机体自身免疫,免疫系统进化出多种“预防机制”,它以免疫检查点的形式...

PDL1结合T细胞表面升高的PD1,触发PD1/PDL1轴抑制作用。Anti-PD1或anti-PDL1抗体阻断PD1与PDL1的相互作用,消除CD8+T细胞的抑制作用,从而增强抗肿瘤活性。与此同时,免疫检查点阻断(immune checkpoint blockade,ICB)的临床成功引起了人们对了解T细胞耗竭作为开发更有效的免疫疗法组合和识别反应的生物标志物的兴趣。肿瘤...

Indeed, phase III clinical trials have revealed that therapies such as ipilimumab and pembrolizumab which target the CTLA4 and PD-1 immune checkpoints, respectively, have raised the three-year survival of patients with melanoma to ∼70%, and overall survival (>5 years) to ∼30%. Despite ...
