Abstract

Coxsackievirus and adenovirus receptor (CAR) from which the cytoplasmic domain had been deleted and glycosylphosphatidylinositol (GPI)-anchored CAR lacking both transmembrane and cytoplasmic domains were both capable of facilitating adenovirus 5-mediated gene delivery and infection by coxsackievirus B3. These results indicate that the CAR extracellular domain is sufficient to permit virus attachment and entry and that the presence of a GPI anchor does not prevent infection.

摘要

缺失细胞质结构域的柯萨奇病毒和腺病毒受体(CAR)以及既缺乏跨膜结构域又缺乏细胞质结构域的糖基磷脂酰肌醇(GPI)锚定型CAR,都能够促进腺病毒5介导的基因传递以及柯萨奇病毒B3的感染。这些结果表明,CAR细胞外结构域足以允许病毒附着和进入,并且GPI锚的存在并不妨碍感染。
