一般說明

程序性细胞死亡1配体1(PD-L1),又称分化簇(CD274)或B7同源物1(B7-H1),是不断增长的B7免疫分子家族的成员。PD-L1是一种细胞表面免疫球蛋白,胞外区有两个Ig样结构域和一个短胞质结构域。该蛋白在心脏、骨骼肌、胎盘和肺中高表达,在胸腺、脾脏、肾脏和肝脏中弱表达。PD-L1在活化的T细胞、B细胞、树突状细胞、角质形成细胞和单核细胞上表达。编码它的基因位于人类染色体9p24.1。

生化/生理作用

程序性细胞死亡1配体1(PD-L1)参与细胞和体液免疫反应的调节。(4)脂多糖 (LPS) 和干扰素-γ(IFNG)激活后,PD-L1在T细胞和B细胞、树突状细胞、角质形成细胞和单核细胞中上调,并在表面Ig交联激活的B细胞中上调。PD-L1以白细胞介素-2依赖性方式和程序性细胞死亡1(PDCD1)非依赖性方式参与共刺激信号,该信号对T细胞增殖以及白细胞介素-10(IL10)和IFNG的产生至关重要。

PD-1 (CD279)-PD-L1 (CD274) inhibitory signaling is critical for cancer immune evasion, and thus has become one of the major targets in anticancer immunotherapy. There are several studies that demonstrate the potent effects of posttranslational modifications of CD274 on immune inactivation
