人类免疫缺陷病毒1型(艾滋病毒-1)的流行仍然是对全球公共卫生的主要威胁,全世界约有3 800万人感染了艾滋病毒-1。然而,目前还没有针对HIV-1的预防性疫苗。在最近的一项研究中,Leggat和他的同事报道了一种种系靶向HIV-1候选疫苗的首次人体试验,该疫苗为60粒eOD-GT8,佐剂为as01b。令人鼓舞的是,该策略在97%(36人中的35人)的疫苗接受者中有效地激活了vrc01类广泛中和抗体(bnAbs)的B细胞前体(种系)。此外,这些活化的前体与成熟的bnAbs具有相同的特性,并获得了大量的体细胞超突变(SHM)和亲和成熟。本研究不仅建立了临床证据
The epidemic of human immunodeficiency virus type 1 (HIV-1) remains a major threat to global public health, with approximately 38 million people living with HIV-1 worldwide. However, a prophylactic vaccine against HIV-1 is not available yet. In a recent study, 1 Leggat and colleagues reported the first-in-human test of a germline-targeting HIV-1 vaccine candidate, eOD–GT8 60-mer adjuvanted withAS01B. Encouragingly, this strategy effectively activated the B cell precursors (germlines) of VRC01-class broadly neutralizing antibodies (bnAbs) in 97%(35 of 36) of vaccine recipients. Moreover, these activated precursors shared properties with mature bnAbs and acquired substantial somatic hypermutation (SHM) and affinity maturation. This study not only establishes the clinical proof
