Recapitulation of HIV-1 Env-antibody coevolution in macaques leading to neutralization breadth.
Abstract
Neutralizing antibodies elicited by HIV-1 coevolve with viral envelope proteins (Env)
in distinctive patterns, in some cases acquiring substantial breadth. We report that
primary HIV-1 envelope proteins-when expressed by simian-human immunodeficiency viruses
in rhesus macaques-elicited patterns of Env-antibody coevolution strikingly similar
to those in humans. This included conserved immunogenetic, structural and chemical
solutions to epitope recognition and precise Env-am ino acid substitutions, insertions
and deletions leading to virus persistence. The structure of one rhesus antibody,
capable of neutralizing 49% of a 208-strain panel, revealed a V2-apex mode of recognition
like that of human bNAbs PGT145/PCT64-35S. Another rhesus antibody bound the CD4-binding
site by CD4 mimicry mirroring human bNAbs 8ANC131/CH235/VRC01. Virus-antibody coevolution
in macaques can thus recapitulate developmental features of human bNAbs, thereby guiding
HIV-1 immunogen design.

Associate Professor in Surgery
Dr. Williams completed a PhD in Biomedical Sciences (Immunology and Microbiology)
from the University of Florida and did his postdoctoral work in the laboratory of
Dr. Barton Haynes at the Duke Human Vaccine Institute (DHVI). The key goals of HIV
vaccine development are to define the host-virus events during natural HIV infection
that lead to the induction of broadly neutralizing antibodies, and to recreate those
events with a vaccine. As a junior faculty member in the DHVI, Dr. W
