Abstract:
以程序性死亡因子 1(PD-1)及其配体 1(PD-L1)为代表的B7/CD28家族在肿瘤免疫治疗中显示出极大的应用潜力,但仍 有很多PD-L1检测阴性患者无法从中受益。作为B7家族成员,人内源性逆转录病毒-H长末端重复关联蛋白2 (HHLA2)分子结 构与PD-L1等其他B7家族成员有一定的同源性和相似性, 对T细胞有共刺激和共抑制作用,在多数实体肿瘤中呈高表达,且在某 些实体肿瘤中表达比PD-L1更广泛;其通过与受体穿膜和免疫球蛋白结构域2(TMIGD2)结合可促进肿瘤免疫逃逸,导致肿瘤的 进展和转移。基于此,HHLA2/TMIGD2有望成为肿瘤免疫治疗新的通路和靶点之一。本文就HHLA2及其受体TMIGD2的分子 结构、生物学功能及其在实体肿瘤中作用的研究进展作一综述。
