我们描述了土拨鼠肝炎病毒核酸在肝脏和其他组织的慢性感染土拨鼠,使用南方和北方印迹杂交技术的研究。单链和共价闭合的环状复制DNA分子与部分双链病毒基因组不同。在大多数动物中,肝脏比任何其他器官含有更多的病毒,但所有研究的肝外器官(脾脏,胸腺,胰腺和肾脏)都含有病毒DNA和大量的病毒RNA。在脾脏中,部分双链病毒基因组的水平高于除肝脏外的任何其他器官,但未检测到复制中间体。在没有可检测的共价闭合环状DNA模板的情况下观察RNA转录物表明肝外组织中的一小部分细胞感染了WHV。
We describe studies of woodchuck hepatitis virus nucleic acids in liver and other tissues of chronically infected woodchucks, using Southern and Northern blot hybridization techniques. Single-stranded and covalently closed circular replicative DNA molecules were distinguished from partly double-stranded virus genomes. In most animals the liver contained more virus than any other organ, but all extrahepatic organs studied (spleen, thymus, pancreas, and kidney) contained viral DNA and significant amounts of viral RNA. In the spleen, partly double-stranded virus genomes were present at higher levels than in any other organ but liver, but nonetheless replicative intermediates were not detected. The observation of RNA transcripts in the absence of detectable covalently closed circular DNA template suggests that a small proportion of cells in extrahepatic tissues are infected with WHV.
