PD1的概念:程序性死亡受体1(Programmed death-1,PD-1 / CD279)是T细胞上表达的抑制性受体,其促进炎性T细胞凋亡并抑制抗炎调节性T细胞凋亡,从而促进自身耐受并预防自身免疫性疾病。为了逃避免疫监视,肿瘤细胞通常通过过度表达PD-L1(结合并激活PD-1的配体)来利用该系统。 抗PD-1单克隆抗体用于阻断PD-L1与...
PD1(programmed cell death 1,PD-1/CD279)是一种单体糖蛋白,由288个氨基酸残基组成,分子量约为50~55kDa,也称为程序性死亡受体1,是激活型T细胞的一种表面受体。目前被证实的PD1配体有两个,分别是程序性死亡配体1(programmed cell death ligand 1,PD-L1/B7-H1)和PD-L2(programmed cell death ligand 2,PD...

cell PD1 (PD1(lo)), myeloid, and T-cell PDL1 (PDL1(hi)) in the tumor microenvironment inversely correlate and dictate the efficacy of anti-PD1 mAb and function of intratumor CD8(+) T cells. In sensitive tumors, we reveal a threshold for PD1 downregulation on tumor-infiltrating CD8(+) ...
