Scientific Focus

Dr. Montefiori’s major research interests are viral immunology and HIV vaccine development, with a special emphasis on neutralizing antibodies. One of his highest priorities is to identify immunogens that generate broadly neutralizing antibodies for inclusion in vaccines. Many aspects of neutralizing antibodies are studied in his laboratory, including mechanisms of neutralization, viral escape from neutralization, epitope diversity among the many different genetic subtypes and geographic distributions of the virus, neutralization epitopes, and the requirements to elicit broadly neutralizing antibodies by vaccination.

Over the years he has explored multiple technologies for measuring neutralizing antibodies and other potential antiviral antibodies, focusing on assay optimization, standardization, validation and high throughput. The scope of his research covers HIV-infected people and nonhuman primate models of simian immunodeficiency virus (SIV) and simian-human immunodeficiency virus (SHIV) infection.

Dr. Montefiori also directs a large vaccine immune monitoring program that operates in compliance with Good Clinical Laboratory Practice and has served as a national and international resource for standardized assessments of neutralizing antibody responses in preclinical and clinical trials of candidate HIV vaccines since 1988. In 2002, he chaired the Antibody Laboratory Standardization Working Group that assisted in the design of the Global HIV Vaccine Enterprise Strategic Plan for HIV vaccines. He currently directs the Core Neutralizing Antibody Laboratories for the HIV Vaccine Clinical Trials Network (HVTN), the NIH Preclinical HIV-1 Vaccine Program, and the Center for HIV/AIDS Vaccine Immunology-Immunogen Design (CHAVI-ID) and, more recently, the Duke Center for HIV/AIDS Research (CFAR). He also directs a large Comprehensive Antibody Vaccine Immune Monitoring Consortium (CAVIMC) as part of the Bill and Melinda Gates Foundation's Collaboration for AIDS Vaccine Discovery (CAVD). He has published over 500 original research papers that have helped shape the scientific rationale for antibody-based HIV vaccines.


Key Projects Underway

  • Ongoing characterization of the global neutralization serotypes of HIV-1
  • Identification of optimal combination of broadly neutralizing antibodies for HIV-1 prevention and treatment
  • Immunologic correlates of protection against the acquisition of HIV infection
  • Structural and immunologic requirements for broadly neutralizing antibody induction
  • Novel HIV-1 vaccine designs

Selected Achievements

  • Established “gold standard” reference strains and validated assays for highly standardized assessments of HIV-1 vaccine-elicited neutralizing antibodies.
  • Tiered categorization of HIV-1 neutralization phenotypes.
  • Detailed analyses of the magnitude, breadth, and complementarity of HIV-1 neutralizing antibodies.
  • Identification of novel neutralization epitopes.
  • First report of the initial HIV-1 autologous neutralizing antibody response targeting a broadly neutralizing epitope.
  • Demonstration that vaccine-elicited neutralizing antibodies can protect against the acquisition of simian-human immunodeficiency virus (SHIV) infection in nonhuman primates.
  • Identification of HIV-1 genetic signatures of neutralization. Translation of this information to vaccine design.
  • Discovery and characterization of complement-mediated antibody-dependent enhancement of HIV-1 infection in vitro. Subsequent identification of C3d and CD21 as the major pathway for complement opsonization by HIV-1. Discovery that HIV-1 acquires complement regulatory proteins (e.g., CD46, CD55 and CD59) as it buds from the surface of host cells and protect the virus from complement-mediated destruction.
  • Role of Fc gamma receptors in potentiating antibody-mediated HIV-1 neutralization through entry inhibition.
  • Demonstration of genetic drift and clade preferences in HIV-1 neutralization epitopes.
