Influenza peptide reactivity within a cohort of age-stratified individuals pre and post vaccination with the 2008/2009 trivalent influenza vaccine

ABSTRACT: The aim of the study was to test the hypothesis that peptide array reactivity will reveal patterns that can be associated with poor or effective neutralization response to seasonal influenza vaccine We diluted patient sera 1:80 and incubated dilutions on a streptavidin-coated glass surface that was printed with biotinylated peptides derived from seasonal strains of influenza hemagglutinin included in the 2008/2009 trivalent influenza vaccine
ORGANISM(S): H3N2 subtype Influenza B virus Homo sapiens H1N1 subtype

Using multivariate linear regression and correcting for multiple hypothesis testing by cross-validation, ee found that patterns of peptide reactivity associated with a poor or effective neutralization response to H1N1 and B strains of influenza.
Project description:The purpose of the study was to assess the patterns of global gene expression in peripheral blood cells before and at three time points after the administration of a trivalent influenza vaccine in human female subjects, and to relate these to the antibody response to the vaccine
Project description:Here we applied systems approaches to investigate the innate and adaptive responses to trivalent inactivated influenza vaccine (TIV) and MF59-adjuvanted TIV (ATIV) in ninety 14-24 month old healthy children.
Project description:The purpose of the study was to assess the patterns of global gene expression in peripheral blood cells before and at three time points after the administration of a trivalent influenza vaccine in human male subjects, and to relate these to the antibody response to the vaccine. The antibody titer data for these subjects is provided as a supplemental file. 119 healthy male human volunteers ages 19 - 41 years were recruited in the study. Whole-blood RNA samples were collected in PaxGene tubes before and at three time points after administration of a trivalent influenza vaccine. Baseline samples (before vaccination) are labeled as day 0. The three additional time points are days 1, 3, and 14 after vaccination. A total of 431 arrays, corresponding to 116 individuals, passed quality control and are included in this data set. These are distributed as follows: Day 0: 111 Samples Day 1: 110 Samples Day 3: 101 Samples Day 14: 109 Samples

Project description:The purpose of the study was to assess the patterns of global gene expression in peripheral blood cells before and at three time points after the administration of a trivalent influenza vaccine in human female subjects, and to relate these to the antibody response to the vaccine 128 healthy female human volunteers ages 19 - 41 years were recruited in the study. Whole-blood RNA samples were collected in PaxGene tubes before and at three time points after administration of a trivalent influenza vaccine. Baseline samples (before vaccination) are labeled as day 0. The three additional time points are days 1, 3, and 14 after vaccination. A total of 417 arrays, corresponding to 110 individuals, passed quality control, corresponded to individuals where at least two of the four arrays in the series were available, and corresponded to individuals who were ethnically homogeneous as determined by identity-by-state and multidimensional scaling analysis of their genotype data. That set of 417 arrays was used for analysis in the associated publication and was therefore included in this GEO upload. These are distributed as follows: Day 0: 107 Samples Day 1: 107 Samples Day 3: 105 Samples Day 14: 98 Samples
Project description:<p>The data consist of the DNA sequences of antibody gene rearrangements from peripheral blood human B cells of subjects vaccinated with trivalent seasonal influenza or monovalent pandemic H1N1 vaccine. Multiple replicate libraries of immunoglobulin heavy chain gene rearrangements were prepared from each subject for each time point.</p>
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.

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 2009 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.
