1399-两步法诱导HIV广谱中和抗体研究

from 聊聊Sci

这些研究资料详细介绍了一种利用恒河猴模型诱导广泛中和抗体(bNAbs)的创新型HIV疫苗设计策略。研究人员开发了一种名为SHIV.5MUT的工程化病毒,它能通过一种两步机制在动物体内高效触发针对V3-聚糖表位的免疫反应。首先,病毒引发初步的V1区域抗体反应,迫使病毒发生变异并缩短V1环,从而暴露关键的免疫靶点。随后,这种结构变化成功激活了多种具备中和广度的B细胞前体,使其产生与人类相似的强效抗体。通过对病毒与抗体协同进化过程的深入分析,该研究为未来开发能够预防人类HIV感染的生殖系靶向疫苗提供了关键的分子蓝图和实验基准。References:Skelly A N, Gristick H B, Li H, et al.
