Synthetic Three-Component HIV-1 V3 Glycopeptide Immunogens Induce Glycan-Dependent Antibody Responses

Eliciting broadly neutralizing antibody (bNAb) responses against HIV-1 is a major goal for a prophylactic HIV-1 vaccine.  One approach is to design immunogens based on known broadly neutralizing epitopes. Here we report the design and synthesis of an HIV-1 glycopeptide immunogen derived from the V3 domain. Rabbit immunization revealed that the synthetic  self-adjuvant glycopeptide could elicit substantial glycan-dependent antibodies that exhibited broader recognition of HIV-1 gp120s than the nonglycosylated V3 peptide.
