综述目的:抗灵长类免疫缺陷病毒感染的唯一明确相关性是存在足够滴度的中和抗体。这种相关性已经使用动物模型通过实验确定,并且数据是可重复的和稳健的。最近的进展使我们更接近于了解抗体如何中和HIV-1,以及它们在体内保护免受感染和疾病方面可能产生的影响,从而进一步加深了这一知识。最近的研究结果-这篇综述将涵盖我们对HIV-1中和抗体的结构基础的理解以及这种理解如何与疫苗设计相关的最新进展,并将其纳入抗体如何影响病毒传播,复制和疾病的更广泛背景中。这些发现的总和为基于诱导中和抗体的原理设计HIV-1疫苗提供了强有力的理论基础,尽管还应记住抗体的其他效应子功能,如补体和抗体介导的细胞免疫,以及CD 4和CD 8 T细胞应答。
Purpose of review The only unequivocal correlate of protection against primate immunodeficiency virus infection is the presence of neutralizing antibody at sufficient titre. This correlate has been determined experimentally using animal models, and the data are reproducible and robust. Recent advances have added further depth to this knowledge by moving us closer to understanding how antibodies neutralize HIV-1, and what effects they may have in vivo with regard to protection from infection and disease. Recent findings This review will cover recent advances in our understanding of the structural basis of HIV-1 neutralization by antibody and how this understanding may relate to vaccine design, and incorporate this into the broader context of how antibodies may influence viral transmission, replication and disease. Summary The sum of these findings provides a strong rationale for designing an HIV-1 vaccine on the principle of induction of neutralizing antibodies, although other effector functions of antibodies such as complement and antibody-mediated cellular immunity should also be borne in mind, as should CD4 and CD8 T cell responses.
