Soluble native-like HIV-1 envelope glycoproteins have shown promise as vaccine candidates as they can induce potent autologous neutralizing responses in rabbits and non-human primates. In this study, monoclonal antibodies were isolated and characterized from rhesus macaques immunized with the BG505 SOSIP.664 trimer to better understand vaccine-induced antibody responses. Our studies reveal a diverse landscape of antibodies recognizing immunodominant strain-specific epitopes and non-neutralizing neo-epitopes. Additionally, we isolated a subset of mAbs against an epitope cluster at the gp120-gp41 interface that recognize the highly conserved fusion peptide and the glycan at position 88 and have characteristics akin to several human-derived broadly neutralizing antibodies. #1: Journal: Biorxiv / Year: 2020 Title: Mapping the immunogenic landscape of native HIV-1 envelope trimers in non-human primates Authors: Cottrell CA / van Schooten J / Bowman CA / Yuan M / Oyen D / Shin M / Morpurgo R / van der Woude P / van Breemen M / Torres JL / Patel R / Gross J / Sewall LM / Copps J / Ozorowski G / Sok D ...Authors: Cottrell CA / van Schooten J / Bowman CA / Yuan M / Oyen D / Shin M / Morpurgo R / van der Woude P / van Breemen M / Torres JL / Patel R / Gross J / Sewall LM / Copps J / Ozorowski G / Sok D / Rakasz EG / Labranche C / Vigdorovich V / Christley S / Sather DN / Montefiori D / Moore JP / Burton DR / Wilson IA / Sanders RW / Ward AB / van Gils MJ | ||||||||||||
