A virus-virus interaction is a measurable difference in the course of infection of one virus as a result of a concurrent or prior infection by a different species or strain of virus. Many such interactions have been discovered by chance, yet they have rarely been studied systematically. Increasing evidence suggests that virus-virus interactions are common and may be critical to understanding viral pathogenesis in natural hosts. In this review we propose a system for classifying virus-virus interactions by organizing them into three main categories: (1) direct interactions of viral genes or gene products, (2) indirect interactions that result from alterations in the host environment, and (3) immunological interactions. We have so far identified 15 subtypes of interaction and assigned each to one of these categories. It is anticipated that this framework will provide for a more systematic approach to investigating virus-virus interactions, both at the cellular and organismal levels.
病毒-病毒相互作用是指一种病毒在感染过程中由于同时或先前感染了不同物种或株的病毒而出现可测量的差异。许多这样的相互作用是偶然发现的,但很少有系统地研究过。越来越多的证据表明,病毒-病毒相互作用很常见,可能对理解自然宿主中的病毒发病机制至关重要。在这篇综述中,我们提出了一种通过将病毒-病毒相互作用分为三类来对其进行分类的系统:(1)病毒基因或基因产物的直接相互作用,(2)宿主环境改变导致的间接相互作用,和(3)免疫学相互作用。到目前为止,我们已经确定了 15 种相互作用亚型,并将每种亚型分配到其中一个类别。预计该框架将为在细胞和机体水平上更系统地研究病毒-病毒相互作用提供一种方法。
