Abstract

Broadly neutralizing antibodies (bnAbs) targeting the human immunodeficiency virus-1 (HIV-1) have played a crucial role in elucidating and characterizing neutralization-sensitive sites on the HIV-1 envelope spike and in informing vaccine development. Continual advancements in identifying more potent bnAbs, along with their capacity to trigger antibody-mediated effector functions, coupled with modifications to extend their half-life, position them as promising candidates for both HIV-1 treatment and prevention. While current pharmacological interventions have made significant progress in managing HIV-1 infection and enhancing quality of life, no definitive cure or vaccines have been developed thus far. Standard treatments involve daily oral anti-retroviral therapy, which, despite its efficacy, can lead to notable long-term side effects. Recent clinical trial data have demonstrated encouraging therapeutic and preventive potential for bnAb therapies in both HIV-1-infected individuals and those without the infection. This review provides an overview of the advancements in HIV-1-specific bnAbs and discusses the insights gathered from recent clinical trials regarding their application in treating and preventing HIV-1 infection.

中和威胁:利用针对 HIV-1 的广泛中和抗体进行治疗和预防。
针对人类免疫缺陷病毒-1(HIV-1)的广谱中和抗体(bnAbs)在阐明和描述 HIV-1 包膜尖峰上的中和敏感位点以及为疫苗开发提供信息方面发挥了至关重要的作用。在确定更强效的 bnAbs 方面不断取得进展,这些 bnAbs 有能力触发抗体介导的效应器功能,再加上对其进行改造以延长半衰期,使它们成为治疗和预防 HIV-1 的有前途的候选药物。虽然目前的药物干预措施在控制 HIV-1 感染和提高生活质量方面取得了重大进展,但迄今为止尚未开发出彻底治愈的方法或疫苗。标准治疗包括每日口服抗逆转录病毒疗法,尽管疗效显著,但可能导致明显的长期副作用。最近的临床试验数据显示,bnAb疗法对HIV-1感染者和非感染者都具有令人鼓舞的治疗和预防潜力。本综述概述了 HIV-1 特异性 bnAbs 的进展,并讨论了从最近的临床试验中收集到的有关其在治疗和预防 HIV-1 感染方面应用的见解。
