Abstract

From what viruses the human immunodeficiency viruses (HIVs) originated is an extremely controversial question. To address this question, we have analyzed nucleotide sequences of simian immunodeficiency viruses (SIVs) and HIVs by using the techniques for understanding molecular evolution. In particular, we compared the nucleotide sequences of whole genomes, gene region by gene region, between a given pair of viruses, including four types of SIVs--isolated from mandrills (Papio sphinx), African green monkeys (Cercopithecus aethiops), sooty mangabeys (Cercocebus atys), and rhesus macaques (Macaca mulatta)--as well as HIVs. Phylogenetic trees for all gene regions examined showed that the present HIVs may have emerged as different variants of SIVs of Old World monkeys, possibly from recombination between viruses related to SIVs.

摘要

人类免疫缺陷病毒(HIV)起源于何种病毒是一个极具争议的问题。为解决这个问题,我们运用理解分子进化的技术分析了猿猴免疫缺陷病毒(SIV)和HIV的核苷酸序列。具体而言,我们在包括从山魈(狮尾狒)、非洲绿猴、黑冠猕猴和恒河猴中分离出的四种SIV以及HIV在内的给定病毒对之间,逐基因区域地比较了全基因组的核苷酸序列。所有检测基因区域的系统发育树表明,目前的HIV可能是作为旧世界猴SIV的不同变体出现的,可能源于与SIV相关病毒之间的重组。
