自从我们中的一个人发表了这篇关于准种与病毒性疾病控制相关性的文章的第一版[1]以来,几个小组已经收集了大量关于病毒准种的信息。对于许多病毒,通过使用逆转录酶和耐热聚合酶扩增(RT-PCR)将从生物样本中提取的病毒RNA直接复制到cDNA中,已经证明了群体水平的极端复杂性。已经揭示了广泛群体异质性的与人类健康相关的两个系统是丙型肝炎病毒(HCV)[2-4]和人类免疫缺陷病毒(HIV)[5-7,及参考文献]。特别引人注目的是,尽管迫切需要阻止艾滋病大流行的发展,但无法生产针对这些病毒中任何一种的有效疫苗[8-11]。此外,抗逆转录病毒抑制剂耐药的HIV-1突变体的系统选择[12-14]极大地限制了抗逆转录病毒治疗的疗效,直到最近联合治疗的令人鼓舞的结果。
Since a first version of this article on the relevance of quasispecies to viral disease control was published by one of us [1], an explosion of information on viral quasispecies has been gathered by several groups. For many viruses, extreme complexity at the population level has been documented by direct copying into cDNA of viral RNA extracted from biological specimens using reverse transcriptase and amplification by thermostable polymerases (RT-PCR).Two systems relevant to human health for which extensive population heterogeneity has been revealed are hepatitis C virus (HCV) [2-4] and the human immunodeficiency viruses (HIV) [5-7, and references therein]. Particularly dramatic has been the inability to produce effective vaccines against any of these viruses [8-11] in spite of an urgent need to stop the progression of the AIDS pandemic. Also, the systematic selection of HIV-1 mutants resistant to antiretroviral inhibitors [12-14] has greatly limited the efficacy of antiretroviral treatments until the recent encouraging results with combination therapy.
