Transient Glycan-shield Reduction Induces CD4-binding Site Broadly Neutralizing Antibodies in SHIV-infected Macaques

Highlights: Out of 115 wildtype HIV-1 Env bearing SHIV infected macaques, only one macaque (T681) developed CD4bs bNAbsCD4bs bNAbs in macaque T681 recognized Env similarly to previously described CDR-H3 dominated human CD4bs bNAbs and exhibited comparable breadth and potencyTransient CD4bs-proximal glycan deletions in macaque T681 preceded bNAb inductionA novel SHIV with CD4bs-proximal glycan holes and enhanced CD4bs antigenicity immunofocused B cell responses to the CD4bs and elicited cross-clade neutralizing responses in 80% of macaques.
