绵羊β逆转录病毒为研究逆转录病毒与宿主之间复杂的相互作用提供了一个独特的模型系统。绵羊肺腺瘤病毒(Jaagsiekte sheep retrovirus,JSRV)是一种致病性外源性逆转录病毒,是绵羊肺腺癌的病原体.绵羊基因组含有至少27个拷贝的内源性逆转录病毒(enJSRVs),其与JSRVs高度相关。enJSRVs在家养绵羊的进化中发挥了几种作用,因为它们能够阻断JSRVs复制周期,并在绵羊孕体发育和胎盘形态发生中发挥关键作用。现有的数据强烈表明,一些显性负enJSRV前病毒(即能够阻止JSRV复制)已在进化过程中积极选择。有趣的是,最近出现了逃避转显性enJSRV基因座的病毒(不到200年前)。因此,这些逆转录病毒的内源化可能今天仍在发生。因此,绵羊为研究逆转录病毒-宿主协同进化提供了一个令人兴奋的独特系统。(Part多作者评论)
Sheep betaretroviruses offer a unique model system to study the complex interaction between retroviruses and their host. Jaagsiekte sheep retrovirus (JSRV) is a pathogenic exogenous retrovirus and the causative agent of ovine pulmonary adenocarcinoma. The sheep genome contains at least 27 copies of endogenous retroviruses (enJSRVs) highly related to JSRV. enJSRVs have played several roles in the evolution of the domestic sheep as they are able to block the JSRV replication cycle and play a critical role in sheep conceptus development and placental morphogenesis. Available data strongly suggest that some dominant negative enJSRV proviruses (i.e. able to block JSRV replication) have been positively selected during evolution. Interestingly, viruses escaping the transdominant enJSRV loci have recently emerged (less than 200 years ago). Thus, endogenization of these retroviruses may still be occurring today. Therefore, sheep provide an exciting and unique system to study retrovirus-host coevolution. (Part of a Multi-author Review)
