摘要: 程序性死亡配体-1(PD-L1)是新发现的B7家族的成员,与其受体程序性死亡受体-1(PD-1)结合后对免疫应答发挥负性调节作用。PD-1及PD-L1在正常组织及癌组织中的分布存在差异,有可能为恶性肿瘤的免疫治疗提供新的方法。

Abstract: Programmed death1ligand(PDL1) is a new member of B7 family,whose  receptor  is programmed death1(PD1). The interaction between PDL1 and PD1 can downregulate the activation of immune response.There are some differences in the expression of  PD1 and PDL1 in normal tissues and tumor tissues, which may provide a new way for the immunotherapy of carcinoma.
