Abstract

Porcine reproductive and respiratory syndrome virus (PRRSV) is not only a poor inducer of type I interferon but also inhibits the efficient induction of type I interferon by porcine transmissible gastroenteritis virus (TGEV) and synthetic dsRNA molecules, Poly I:C. However, the mechanistic basis by which PRRSV interferes with the induction of type I interferon in its natural host cells remains less well defined. The purposes of this review are to summarize the key findings in supporting the post-transcriptional control of type I interferon in its natural host cells and to propose the possible role of translational control in the regulation of type I interferon induction by PRRSV.

摘要

猪繁殖与呼吸综合征病毒(PRRSV)不仅是Ⅰ型干扰素的弱诱导剂,还能抑制猪传染性胃肠炎病毒(TGEV)和聚肌胞(Poly I:C)等合成 dsRNA 分子诱导Ⅰ型干扰素的有效产生。然而,PRRSV 在其自然宿主细胞中干扰Ⅰ型干扰素产生的机制基础仍不明确。本综述旨在总结支持Ⅰ型干扰素在其自然宿主细胞中转录后调控的关键发现,并提出 PRRSV 调控Ⅰ型干扰素诱导的翻译调控可能作用。
