缺陷干扰(DI)病毒颗粒在许多(可能是所有)动物病毒复制过程中产生(Huang and巴尔的摩1977; Perrault 1981)。它们的特征性基因组含有标准(感染性)病毒基因组的缺失,通常是大多数缺失。这些缺失意味着DI病毒只能在与标准病毒共感染的细胞中复制。这种共感染通常导致DI病毒群的增加和伴随的标准病毒的减少-干扰现象(Huang and巴尔的摩1977; Holland et al. 1980; Perrault 1981)。DI病毒的这些和其他特性总结见表1。应强调DI病毒核酸在由标准病毒合成的外壳蛋白的正常补体中被取代这一点,因为DI和标准病毒在抗原性上是相同的,它们应以相同的方式刺激和应答宿主免疫应答。DI病毒在复制和降解方面对标准病毒的密切生化依赖性解释了为什么在大多数情况下,干扰对同源标准病毒是特异性的。关于DI病毒的生物化学特性,读者可参考Huang和巴尔的摩(1977)、Holland等(1980)和Perrault(1981)的综述。
Defective interfering (DI) virus particles are generated during the replication of many, possibly all, animal viruses (Huang and Baltimore 1977; Perrault 1981). They characteristically have a genome which contains deletions, often of the majority, of the standard (infectious) virus genome. These deletions mean that DI virus can only replicate in cells co-infected with standard virus. Such co-infection normally results in the enhancement of the DI virus population and a concomitant reduction in standard virus — the phenomenon of interference (Huang and Baltimore 1977; Holland et al. 1980; Perrault 1981). These and other properties of DI viruses are summarised in Table 1. The point that DI virus nucleic acid is encapsidated in the normal complement of coat proteins synthesized by standard virus should be emphasized, since it follows that DI and standard virus are antigenically identical and that they should stimulate and respond to host immune responses in the same way. The intimate biochemical dependence of DI virus on standard virus for its replication as well as encapsidation explains why, for the most part, interference is specific for the homologous standard virus. For an account of the biochemical properties of DI viruses the reader is referred to reviews by Huang and Baltimore (1977), Holland et al. (1980) and Perrault (1981).
