Program Description

The Genome Analysis Core (TGAC), within the Human Immunology Section fulfills many of the specialist sequencing needs of the Vaccine Research Center. The VRC is designing, producing and testing candidate immunogens aimed at eliciting neutralizing antibodies against a number of human pathogens including HIV, Malaria, Influenza, RSV and SARS-CoV-2. At the core of this effort lies the requirement to elicit antibodies that use particular IgH and IgL chain gene pairs. For evaluation of vaccine candidates, the evolution of such antibodies, and thus the effectiveness of the vaccine, needs to be monitored using a variety of molecular techniques that culminate in single-cell NGS of pathogen-specific B cell Ig genes. In addition, passive antibody applications necessarily depend on the identification and sequencing of neutralizing pathogen-specific antibodies in infected and/or convalescent people. Similarly, vaccines being developed by the VRC that aim to elicit T cell immunity, such as those against TB, malaria and cancer, require analysis at the level of TCR sequences.  To complement these studies of immune adaptive receptor use, the VRC also investigates host genomic associations with vaccine responses and disease progression, the microbiome, pathogen sequence diversity within and among infected people, and host cellular reservoirs of pathogens. To achieve these goals the TGAC has developed a broad portfolio of next-generation sequencing methodologies. These assays are performed on samples from multiple species including humans, NHP and various rodents.

Biography

Dr. Douek studied medicine at the Universities of Oxford and London, receiving academic scholarships from both institutions. He then practiced internal medicine and became a Member of the Royal College of Physicians (London) in 1993. He was awarded a Wellcome Trust Clinical Graduate Training Fellowship to pursue a Ph.D. in immunology at the University of London, which he earned in 1997. He completed his postdoctoral work at the Rockefeller University and the University of Texas Southwestern Medical Center, Dallas, where he was named assistant professor in infectious diseases (2000). Dr. Douek was appointed to a tenure-track position in the VRC Laboratory of Immunology in November 2000. He was converted to a tenured senior investigator position in February 2007, the year in which he was presented with the World AIDS Day Award. He serves as chief of the Human Immunology Section at the VRC. He initiated the establishment of the Genome Analysis Core and serves as its Chief.​​
