猪繁殖与呼吸综合征病毒(Porcine reproductive and respiratory syndrome virus,PRRSV)已困扰养猪业30多年,造成了巨大的经济损失。目前有不同的商业疫苗,但工具有限。迄今为止,至少有六种潜在的宿主因子被确定为PRRSV感染的关键受体。其中,CD 163分子是PRRSV生命周期中最重要和最关键的分子,负责介导病毒的脱壳和基因组释放。它决定了靶细胞对病毒的易感性。几种PRRSV非允许细胞(如PK-15、3D 4/21和BHK-21)被证明在猪CD 163蛋白表达的存在下变得对PRRSV感染完全敏感。因此,CD 163已成为设计破坏CD 163与病毒糖蛋白之间相互作用的新型抗病毒分子或培育抗PRRSV感染的基因修饰动物的靶标。本文就近年来通过靶向CD 163受体抑制PRRSV复制的研究进展作一综述。此外,还讨论了在病毒生命周期的脱壳过程中是否存在其他与CD 163相互作用的潜在分子。
Porcine reproductive and respiratory syndrome virus (PRRSV) has plagued the pig industry for more than 30 years and causes great economic losses. At present different commercial vaccines are available but limited tools. Until now at least six potential host factors are identified as the key receptors for PRRSV infection. Among them, CD163 molecule is the most important and critical in PRRSV life cycle responsible for mediating virus uncoating and genome release. It determines the susceptibility of target cells to the virus. Several PRRSV non-permissive cells (such as PK-15, 3D4/21, and BHK-21) are demonstrated to become completely susceptible to PRRSV infection in the presence of expression of porcine CD163 protein. Therefore, CD163 has become the target for the design of novel antiviral molecules disrupting the interaction between CD163 and viral glycoproteins, or the breeding of gene-modified animals against PRRSV infection. In this review, we comprehensively summarize the recent progress in inhibition of PRRSV replication via targeting CD163 receptor. In addition, whether there are other potential molecules interacting with CD163 in the process of uncoating of virus life cycle is also discussed.
