背景(Background)
分化簇86(CD86)也称为B淋巴细胞活化抗原B7-2,是一种I型膜蛋白,是免疫球蛋白超家族的成员,在交叉树突细胞、朗格罕斯细胞、外周血树突细胞、记忆B细胞和生发中心B细胞上组成型表达。此外,B72在单核细胞上的表达水平较低,可以通过干扰素γ上调。CD86是T细胞表面两种不同蛋白质的配体:CD28(用于自动调节和细胞间结合)和CTLA-4(用于减弱调节和细胞分离)。CD86与CD80协同作用以激活T细胞。最近的研究表明,B7-2促进了成熟APC库的产生,并促进了APC的功能和存活。此外,B7蛋白还通过激活巨噬细胞中的NF-κB信号通路参与先天免疫反应。因此,CD86被视为免疫治疗的有前景的候选者。霍奇金淋巴瘤患者的CD86+巨噬细胞是一线治疗潜在无反应的独立标志物。
