HIV包膜糖蛋白(Env)被自身聚糖密集覆盖,这有助于保护它不被人体免疫系统识别。在这里,我们研究了一个特别有效的广泛中和抗体家族(Abs)如何进化出共同的和独特的结构特征来对抗聚糖屏蔽,并与HIV Env的聚糖和蛋白质成分相互作用。推断出的种系抗体已经含有一个聚糖和一个短蛋白片段的潜在结合袋。亲和成熟随后导致不同的进化分支,这些分支要么专注于单个聚糖和蛋白质片段(如Ab PGT124),要么参与多个聚糖(如Abs PGT121-123)。此外,通过选择适当的初始抗体形状来防止位阻,可以避免其他周围的聚糖。这些分子识别课程对于能够识别或容纳聚糖的工程蛋白非常重要。
The HIV envelope glycoprotein (Env) is densely covered with self-glycans that should help shield it from recognition by the human immune system. Here we examine how a particularly potent family of broadly neutralizing antibodies (Abs) has evolved common and distinct structural features to counter the glycan shield and interact with both glycan and protein components of HIV Env. The inferred germline antibody already harbors potential binding pockets for a glycan and a short protein segment. Affinity maturation then leads to divergent evolutionary branches that either focus on a single glycan and protein segment (e.g. Ab PGT124) or engage multiple glycans (e.g. Abs PGT121-123). Furthermore, other surrounding glycans are avoided by selecting an appropriate initial antibody shape that prevents steric hindrance. Such molecular recognition lessons are important for engineering proteins that can recognize or accommodate glycans.
