Neonatal Rhesus Macaques Have Distinct Immune Cell Transcriptional Profiles following HIV Envelope Immunization.
Abstract
HIV-1-infected infants develop broadly neutralizing antibodies (bnAbs) more rapidly
than adults, suggesting differences in the neonatal versus adult responses to the
HIV-1 envelope (Env). Here, trimeric forms of HIV-1 Env immunogens elicit increased
gp120- and gp41-specific antibodies more rapidly in neonatal macaques than adult macaques.
Transcriptome analyses of neonatal versus adult immune cells after Env vaccination
reveal that neonatal macaques have higher levels of the apoptosis regulator BCL2 in
T cells and lower levels of the immunosuppressive interleukin-10 (IL-10) receptor
alpha (IL10RA) mRNA transcripts in T cells, B cells, natural killer (NK) cells, and
monocytes. In addition, immunized neonatal macaques exhibit increased frequencies
of activated blood T follicular helper-like (Tfh) cells compared to adults. Thus,
neonatal macaques have transcriptome signatures of decreased immunosuppression and
apoptosis compared with adult macaques, providing an immune landscape conducive to
early-life immunization prior to sexual debut.

Associate Professor in Medicine
My research focuses on the interactions of T cells and B cells during infection or
following vaccination. I am particularly interested in the inter- and intracellular
events that take place within germinal centers, the anatomic site of antibody evolution
during an immune response.
Guido Ferrari
Professor in Surgery
The activities of the Ferrari Laboratory are based on both independent basic research
and immune monitoring studies. The research revolves around three main areas of interest:
class I-mediated cytotoxic CD8+ T cell responses, antibody-dependent cellular cytotoxicity
(ADCC), gene expression in NK and T cellular subsets upon infection with HIV-1. With
continuous funding over the last 11 years from the NIH and Bill & Melinda Gates Foundation
along with many other productive collaborations wi

Wilburt C. Davison Distinguished Professor
Dr. Permar's work focuses on the development of vaccines to prevent vertical transmission
of neonatal viral pathogens. She has utilized the nonhuman primate model of HIV/AIDS
to characterize the virus-specific immune responses and virus evolution in breast
milk and develop a maternal vaccine regimen for protection against breast milk transmission
of HIV. In addition, Dr. Permar's lab has advanced the understanding of HIV-specific
immune responses and virus evolution in vertically-transmitting an
Kevin O'Neil Saunders
Associate Professor in Surgery
The Saunders laboratory aims to understand the immunology of HIV-1 antibodies and
the molecular biology of their interaction with HIV-1 envelope (Env) glycoprotein.
Our overall goal is to develop protective antibody-based vaccines; therefore, the
laboratory has two sections–antibody repertoire analysis and immunogen design.
Our research premise is that vaccine-elicited antibodies will broadly neutralize HIV-1
if they can bind directly to the host glycans on Env. However, Env glycans are

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
