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 TIV (6 vaccinees) or LAIV (6 vaccinees), and blood samples isolated at day 0 and at day 7 post-vaccination. Cell subsets (B cells, Monocytes, mDCs and pDCs) were FACS-sorted from frozen PBMCs. Microarrays were performed using amplified total RNA.
Project description:Dendritic cells (DC) localize throughout the body, where they sense and capture invading pathogens to induce protective immune responses. Hence, harnessing the biology of tissue-resident DC is crucial for the rational design of vaccines against pathogens. Herein, we characterized the transcriptomes of four antigen presenting cell (APC) subsets from the human vagina (vLC, vCD14- DC, vCD14+ DC, vMM-NM-&) and compared them to those of three skin DC (sDC) subsets and blood myeloid DC. We find that APC genomic fingerprints are significantly influenced by the tissue of origin as well as by individual APC subsets. Nonetheless, CD14+ APC from both vagina and skin are geared towards innate immunity and pro-inflammatory responses, whereas CD14- DC, particularly sLC, vLC, and vCD14- DC, display both Th2-inducing and regulatory phenotypes. We also identified vAPC subset-specific cellular and functional biomarkers that will guide the design of mucosal vaccines against sexually transmitted pathogens. Vaginal and skin tissues were obtained from female patients who underwent pelvic or cosmetic surgeries under protocols approved by the Institutional Review Board (IRB) of Baylor Research Institute (BRI). Patients were not infected with HIV, HCV or TB and did not display inflammation in the tissues. No other diagnosis information was available. Blood from healthy female volunteers was obtained under a protocol approved by the IRB of BRI. 87 total samples. 6 Blood mDC; 16 Dermal CD1c+CD14-; 10 Epidermal LC; 12 Vaginal CD1c+CD14-; 13 Vaginal CD1c+CD14+; 7 Vaginal HLADR- w/ 2 replicates (Vaginal HLADR-_VM610 and Vaginal HLADR-_VM611); 9Vaginal LC; 14 Vaginal Macrophage.
Project description:Systems approaches have been used to describe molecular signatures driving immunity to influenza vaccination in humans. Whether such signatures are similar across multiple seasons, and in diverse populations is unknown. We applied systems approaches to study immune responses in young and, elderly subjects vaccinated with the seasonal influenza vaccine across 5 consecutive seasons. During the 2010 Influenza season, healthy adults were vaccinated with TIV, 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.
