Project description:<p>We developed an improved high throughput sequencing approach to measure the quantities and sequences of the repertoire of antibody heavy chain RNA in a blood sample. Using this approach we analyzed the antibody repertoire in response to yearly vaccinations with influenza vaccines TIV and LAIV in healthy adults in two subsequent years. We determined vaccine response patterns specific to LAIV and TIV and found antibody sequences that were shared between two samples of the same individuals following influenza vaccination in subsequent years, thereby providing a genetic measurement of B-cell memory recall.</p>

Project description:Proteomic profiling of serum antibody repertoire response to FluZone trivalent influenza vaccine in four healthy human subjects. Dataset consists of collected pre-vaccination (Day 0) and post-vaccination (Days 28 and 180) serum IgG samples enriched by affinity chromatography against individual monovalent inactivated components of the 2011-2012 trivalent vaccine (H1 A/California/07/2009 X-179A, H3 A/Victoria/210/2009, and B/Brisbane/60/2008).
Project description:Proteomic analysis of serum IgG antibody repertoire against influenza vaccine HAs in infant donors vaccinated with Fluzone 2017-18/18-19. Dataset consists of peak-response (days 14 and 21 post-vaccination) serum IgG samples eluted by affinity chromatography against IAV or IBV hemagglutinin and the flow-throughs.
Project description:Proteomic analysis of serum IgG antibody repertoire against influenza vaccine H1 (H1N1 A/California/7/2009) and H3 (H3N2 A/Texas/50/2012) in young, middle-aged, and elderly donors vaccinated with Fluzone 2013-14/14-15. Dataset consists of peak-response (days 21-28 post-vaccination) serum IgG samples eluted by affinity chromatography against H1 and H3 vaccine or hemagglutinin and the flow-throughs.

Project description:We examined the accessible chromatin differences between circulating B cell subsets post-vaccination. Using FCRL5 as a marker of Tbet expressing B cells, we sorted FCRL5+ (Tbet+) and FCRL5- (Tbet-) memory B cells, and antibody secreting plasmablasts at day 7 and day 14 post-vaccination. Additionally, we used H1 B cell tetramers to track cells responding to the influenza vaccine in a subset of samples. These data provide insights into the accessible chromatin landscape of distinct B cell subsets that respond to influenza vaccination.
Project description:Systems vaccinology has emerged as an interdisciplinary field that combines systems wide measurements and network and predictive modeling applied to vaccinology. Here we used the systems vaccinology approach to study the molecular mechanisms underlying the innate responses to the trivalent inactivated influenza (TIV) and live attenuated influenza (LAIV) vaccination in humans, and to identify early gene signatures that predict the magnitude of the antibody responses to influenza vaccination. During the 2008 influenza season, healthy adults were vaccinated with LAIV (28 vaccinees), and blood samples isolated at days 0, 3, 7 post-vaccination. Microarrays were performed using total RNA extracted from the peripheral blood mononuclear cells of vaccinees.
