在仓鼠细胞中表达的人类HLA-A*0201等位基因不是5型腺病毒纤维的高亲和力受体。

Abstract

The coxsackie B virus and adenovirus receptor (CAR) and the major histocompatibility complex (MHC) class I alpha2 domain have been identified as high-affinity cell receptors for adenovirus type 5 (Ad5) fiber. In this study we show that CAR but not MHC class I allele HLA-A*0201 binds to Ad5 with high affinity when expressed on hamster cells. When both receptors are coexpressed on the cell surface of hamster cells, Ad5 fiber bind to a single high-affinity receptor, which is CAR.

摘要

柯萨奇B病毒和腺病毒受体(CAR)以及主要组织相容性复合体(MHC)I类α2结构域已被确定为5型腺病毒(Ad5)纤维的高亲和力细胞受体。在本研究中,我们发现,当在仓鼠细胞上表达时,CAR而非MHC I类等位基因HLA-A*0201能以高亲和力与Ad5结合。当两种受体在仓鼠细胞表面共表达时,Ad5纤维与单一的高亲和力受体结合,该受体即为CAR。
