Description :CD274, also known as B7-H1 or programmed death ligand 1 (PD-L1), is a 40 kD type Itransmembrane protein and a member of the B7 family within the immunoglobulin receptorsuperfamily. It is expressed on T cells, B cells, NK cells, dendritic cells, IFN-γ activatedendothelial cells, and monocytes. B7-H1 is one of the ligands of PD-1. The interaction of B7-H1with PD-1 plays an important role in the inhibition of T cell responses. Other studies haveshown that B7-H1 is able to costimulate T cell growth and cytokine production. CD274 isinvolved in costimulation essential for T cell proliferation and production of IL-10 and IFN-γ, inan IL-2-dependent and a PD-1-independent manner. Its interaction with PD-1 inhibits T cellproliferation and cytokine production.

被 PeterLinsley 鉴定,而且免疫抑制功能也是在 1994 年被 Jeffrey Bluestone 发现。但Allison 始终对外宣称他是发明了 CTLA-4 抗体治疗肿瘤的。James Allison 与他自己牌照为CTLA-4的保时捷 911 跑车而陈列平教授率先克隆并鉴定了 B7-H1 分子(即现在的 PD-L1)做出的开创工作(1999 年)。陈列平教授率先证明了 B7-H1 蛋白在许多人肿瘤里大量地表达,为临床试验奠定基础(2002 年)。Tasuku Honjo 这时才开始了解到 10 年前
,PD-1/PD-L1这么值钱,大家一定好奇它到底是什么鬼。 PD-1全名是程序性死亡分子1(programmed death-1)是Ishida等[1]通过消减杂交技术于1992年发现的[2],是CD28家族成员,胞质区含有2个酪氨酸残基,1个位于靠近N端的免疫受体酪氨酸抑制基序(ITIM)中,另一个1个位于靠近C端的免疫受体酪氨酸转化基序(ITSM)中[2]。 PD-L1(CD274)是B7家族成员,是PD-1的配体,属于1型跨膜蛋白,全长290个氨基酸,包含1个IgV样
了 B7 家族的第三个成员 B7-H1(即日后的 PD-L1)[2]。2000 年,Tasuku Honjo 教授等人证明了 PD-L1 能与 PD-1 结合,进而抑制 T 细胞的增殖与细胞因子的分泌,负调控淋巴细胞的激活,从此,B7-H1 被正式命名为 PD-L1(陈列平教授则继续使用「B7-H1」命名)[3]。2003年,陈列平教授第一次成功地使用 PD-L1 封闭抗体联合 T 细胞回输技术治愈了约 60% 的头颈癌小鼠[4]。2014 年 12 月,首个应用于肿瘤治疗的抗 PD-1 抗体
