病毒血症控制者(VC)和精英控制者/抑制者(ES)维持对HIV-1复制的控制。一些研究表明,控制是有缺陷的病毒株感染的结果,而另一些研究则表明宿主免疫因素起着关键作用。在这里,我们记录了两个HIV-1传播对:一个由疾病进展的患者和成为ES的个体组成,第二个由疾病进展的患者和VC组成。与另一个ES传播对相反,从所有患者中分离的病毒都具有完全复制能力。这些数据表明,一些VC和ES感染了HIV-1分离株,这些分离株在体外复制旺盛,并能够在体内引起进行性疾病。这些数据表明,宿主因素在控制HIV-1感染中起着主导作用,因此有可能通过治疗性疫苗接种来控制完全致病的HIV-1分离株。
Viremic controllers (VC) and elite controllers/suppressors (ES) maintain control over HIV-1 replication. Some studies suggested that control is a result of infection with a defective viral strain while others suggested host immune factors play a key role. Here we document two HIV-1 transmission pairs: one consisting of a patient with progressive disease and an individual who became an ES, and the second consisting of a patient with progressive disease and a VC. In contrast to another ES transmission pair, virus isolated from all patients was fully replication competent. These data suggests that some VC and ES are infected with HIV-1 isolates that replicate vigorously in vitro and are able to cause progressive disease in vivo. These data suggest that host factors play a dominant role in control of HIV-1 infection, thus it may be possible to control fully pathogenic HIV-1 isolates with therapeutic vaccination.
