摘要
自然杀伤细胞2族成员D(natural killer group 2 member D,NKG2D)是由NK细胞表达的一种免疫受体,可识别靶细胞表面上的人类主要组织相容性复合体Ⅰ类多肽相关序列(major histocompatibility complex Class I polypetide-related chain,MIC)A/B。NKG2D与MICA/B的相互作用,在病毒感染和癌症的免疫监视中发挥重要作用。该文通过膜结合型MICB下调、分泌型MICB增多及MICB基因多态性三部分对MICB/NKG2D信号通路在免疫逃逸中的研究进展进行综述。
Natural killer group 2 member D(NKG2D)is an immune receptor expressed by NK cells that recognizes the human major histocompatibility complex class I polypetide-related chain(MIC)A/B on the cell surface.The interaction between NKG2D and MICA/B plays an important role in the immunosurveillance of viruses infection and cancers.In this article,we review the research progress of the MICB/NKG2D signaling pathway in immune escape including three parts:down-regulation of membrane-bound MICB,increase of secretory MICB,and polymorphism of MICB genes.
