Xenoglycosylation of the HIV-1 Glycan Shield Promotes Cross-Clade Neutralization and Diverse Human Antibody Lineages
Despite advances in HIV-1 envelope glycoprotein (Env)-based vaccine design, eliciting broadly neutralizing antibodies (bNAbs) remains a central challenge. Here, we identify core (1,3)-fucose as a key modulator of neutralizing antibody (NAb) induction and breadth. Uncleaved prefusion-optimized (UFO) trimers and self-assembling protein nanoparticles (SApNPs) produced in High Five (Hi5) insect cells…
