Diverse antibody genetic and recognition properties revealed following HIV-1 envelope glycoprotein immunization.

ABSTRACT: Isolation of mAbs elicited by vaccination provides opportunities to define the development of effective immunity. Ab responses elicited by current HIV-1 envelope glycoprotein (Env) immunogens display narrow neutralizing activity with limited capacity to block infection by tier 2 viruses. Intense work in the field suggests that improved Env immunogens are forthcoming, and it is therefore important to concurrently develop approaches to investigate the quality of vaccine-elicited responses at a higher level of resolution. In this study, we cloned a representative set of mAbs elicited by a model Env immunogen in rhesus macaques and comprehensively characterized their genetic and functional properties. The mAbs were genetically diverse, even within groups of Abs targeting the same subregion of
