PD-1 and PD-L1 inhibitors - Wikipedia
PD-1 inhibitors and PD-L1 inhibitors are a group of checkpoint inhibitor anticancer drugs that block the activity of PD-1 and PDL1 immune checkpoint proteins present on the surface of cells. Immune checkpoint inhibitors are emerging as a front …
一文读懂“抗癌神药”——PD-1抑制剂 - 知乎 - 知乎专栏
PD-1/PD-L1单抗就是分别作用于肿瘤细胞上PD-L1或T细胞上PD-1位点,阻止两者相互结合,激活免疫细胞杀伤肿瘤。 大家可能觉得,这两种药物其实是针对同一免疫通路的两个端点,机制上似乎是一致的。 其实不然,两者在药物设计、作用机制到临床疗效,甚至耐药处理上都有不同之处。 有研究表明,PD-L1抗体阻断作用更强,并且因为其只阻断PD-L1,与PD-1结合,而保留了巨噬细胞的PD-L2,可有效地避免间质性肺炎等副作用的发生。 理论上PD-L1单抗可更全面激活免疫 …

2020年7月20日 · 1:人体的 T淋巴细胞 是免疫细胞,能够识别并且杀灭肿瘤细胞; PD-1 是T淋巴细胞的调节蛋白,但是抑制淋巴细胞的免疫杀伤左右,好处是避免T淋巴细胞杀伤了正常的人体细胞,弊端是降低了T淋巴细胞对肿瘤的杀灭作用,从而导致肿瘤的发生; 2:PD-L1是肿瘤细胞产生的配体蛋白,能够和T淋巴细胞的PD-1相结合,T淋巴细胞的免疫识别功能被抑制,这样T淋巴细胞就不会杀灭带有PD-L1的肿瘤细胞,这样肿瘤就能顺利生长了; 3:真是基于以上的原理,PD …
