HIV-1广泛的遗传多样性对开发有效和持久的HIV疫苗构成了重大障碍。这种可变性不仅使得难以确定免疫应答应针对的靶标,而且还赋予病毒快速逃避有效免疫应答的能力。在这里,我们描述了最近的调查的遗传多样性的HIV-1在传播和病毒的演变,因为它适应宿主免疫环境在HIV-1感染的急性期。这些研究增加了我们对HIV-1感染早期阶段病毒学的理解,并为不同HIV-1毒株的病毒复制和免疫控制机制提供了重要见解。这些知识将为设计更智能、更有效的疫苗提供信息,这些疫苗能够诱导对HIV-1的免疫控制。
The extensive genetic diversity of HIV-1 presents a significant barrier to the development of an effective and durable HIV vaccine. This variability not only makes it difficult to identify the targets against which immune responses should be directed, but it also confers on the virus the capacity for rapid escape from effective immune responses. Here, we describe recent investigations of the genetic diversity of HIV-1 at transmission and of the evolution of the virus as it adapts to the host immune environment during the acute phase of HIV-1 infection. These studies increase our understanding of the virology of the earliest stages of HIV-1 infection and provide critical insights into the mechanisms underlying viral replication and immune control of diverse HIV-1 strains. Such knowledge will inform the design of smarter, more effective, vaccines capable of inducing immune control of HIV-1.
