Gene expression profiles associated with humoral response to influenza vaccine, Vaxigrip, in young and elderly subjects of Chinese ethnicity in Singapore

ABSTRACT: While studying influenza vaccine-induced responses, the elderly are typically considered as a homogeneous population. However, chronological age alone is insufficient in defining immune responsiveness of individuals. In this study, a stratified cohort of elderly (65 year old and above) and young (below 35 year old) individuals was recruited to study the heterogeneity of influenza vaccine-induced responses and identify innate signatures including gene expression profiles defining vaccine immunogenicity. The study was conducted in Singapore, a tropical setting without well-defined influenza seasons.

Ethnicity-specific Skeletal Muscle Transcriptional Signatures and Their Relevance to Insulin Resistance in Singapore

Project description:Context: Insulin resistance (IR) and obesity differ between ethnic groups in Singapore, with discordant rates of obesity and IR between several ethnic groups. However, the molecular basis underlying these differences are not clear. Objective: As the skeletal muscle (SM) is metabolically relevant to IR, we investigated molecular pathways in SM that are associated with ethnic differences in IR, obesity and related traits. Design, Setting and Main Outcome measures: We integrated transcriptomic, genomic and phenotypic analyses in 156 healthy subjects representing three major ethnicities in the Singapore Adult Metabolism Study. Patients: The study contains Chinese (n=63), Malay (n=51) and Asian-Indian (n=42) males, aged 21-40 years, without systemic diseases. Results: We found remarkable diversity in the SM transcriptome between the three ethnicities with >8,000 differentially expressed genes (40% of all genes expressed in SM). Comparison with blood transcriptome from a separate Singaporean cohort showed that >95% of SM expression differences between ethnicities were unique to SM. We identified a network of 46 genes that were specifically down-regulated in Malays, suggesting dysregulation of components of cellular respiration in SM of Malay individuals. We also report 28 differentially expressed gene-clusters, four of which were also enriched for genes that were found in GWAS of metabolic traits and disease and correlated with variation in IR, obesity and related traits. Conclusion: We identified extensive gene expression changes in SM between the three Singaporean ethnicities, and report specific genes and molecular pathways that might underpin and explain the differences in IR between these ethnic groups.

Host cell gene expression in Influenza A virus (A/Singapore/478/2009 (pH1N1)) infected A549 cells at 2, 4, 6, 8 and 10 hours post infection

Project description:We used the microarray data to analyze host cells response on A549 cells infected with Influenza A virus (A/Singapore/478/2009 (pH1N1)) The Influenza A virus (A/Singapore/478/2009 (pH1N1)) infected A549 cells were harvested at 2, 4, 6, 8 and 10 hpi and RNA extraction was performed using standard protocol as described by Affymetrix. The aim of this experiment is to analyze host response to Influenza A virus (A/Singapore/478/2009 (pH1N1)) infection.

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

Project description: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 In this study, serum from 76 study participants, subsetted into young (?30 years old) and elderly (?60 years old) categories were profiled for IgG/IgM antibody reactivity to influenza hemagglutinin peptudes. 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.

Distinct immunological and molecular signatures predict influenza vaccine responsiveness in the elderly (scRNA Seq)

Project description:The significant economic burden and high mortality rates resulting from seasonal influenza outbreaks, especially in high risk groups such as the elderly, represent an important public health problem. The prevailing inadequate efficacy of seasonal vaccines, both conventional and elderly-tailored, is a crucial bottleneck. Consequentially, understanding immunological and molecular mechanisms resulting in differential influenza vaccine responsiveness is a prerequisite for the development of new or improved vaccination strategies. To assess differences within the specific risk group of the elderly, randomly selected individuals (≥ 65 years) were immunized with the adjuvanted influenza vaccine Fluad®. Samples were subjected to single cell transcriptome analysis. The analyses revealed profound features segregating vaccine responders from nonresponders as classified according to their vaccine-induced sero-conversion. Non-responders are characterized by a poorly functional, suppressive phenotype, showing a weaker humoral and cellular immune activation and more suppressive regulatory T and B cells. Triple responders display an efficient immune functionality characterized by the activation of humoral and cellular immunity and the up-regulation of genes related to signaling pathways, including those for anti-viral responses, protein processing and B cell activation. The generated comprehensive high dimensional dataset enables the identification of putative mechanisms and nodes responsible for vaccine non-responsiveness regardless of confounding age-dependent effects.
