Endogenous retrovirus (ERV) genomes integrated into the chromosomal DNA of the host were first detected in chickens and mice as Mendelian determinants of Gag and Env proteins and of the release of infectious virus particles. The presence of ERV was confirmed by DNA hybridization. With complete host genomes available for analysis, we can now see the great extent of viral invasion into the genomes of numerous vertebrate species, including humans. ERVs are found at many loci in host DNA and also in the genomes of large DNA viruses, such as herpesviruses and poxviruses. The evolution of xenotropism and cross-species infection is discussed in the light of the dynamic relationship between exogenous and endogenous retroviruses.
内源性逆转录病毒 (ERV) 基因组整合到宿主的染色体 DNA 中,最初在鸡和小鼠中被检测为 Gag 和 Env 蛋白以及传染性病毒颗粒释放的孟德尔决定因素。ERV 的存在通过 DNA 杂交得到证实。随着完整的宿主基因组可供分析,我们现在可以看到病毒在包括人类在内的许多脊椎动物物种的基因组中广泛入侵。ERV 存在于宿主 DNA 的许多基因座中,也存在于疱疹病毒和痘病毒等大型 DNA 病毒的基因组中。根据外源性和内源性逆转录病毒之间的动态关系,讨论了嗜异性和跨物种感染的进化。
