ABSTRACT: Metabolomics analysis of C57BL/6 mouse lungs infected with influenza A/Vietnam/1203/04 (H5N1) HALo virus, mock infected with PBS, or untreated.
Project description:Metabolomics analysis of C57BL/6 mouse lungs infected with influenza A/Vietnam/1203/04 (H5N1) HALo virus, mock infected with PBS, or untreated.
Project description:Metabolomics analysis of C57BL/6 mouse lungs infected with influenza A/California/04/09 (H1N1) virus, mock infected with PBS, or untreated.
Project description:The pathogenesis of avian influenza A H5N1 virus in human has not been clearly elucidated. There have been increasing evidence suggesting a role for virus-induced cytokine dysregulation in contributing to the pathogenesis of human H5N1 disease. However, the role of aberrant innate immune response in human lungs infected by avian influenza H5N1 virus has not been explored and direct evidence for inappropriate innate responses in lungs of avian influenza H5N1 virus infected patients is lacking.
Project description:The cellular transcriptome of C57BL/6 mouse lungs was profiled by mRNA-Seq analysis at multiple time points in response to infection with influenza A/California/04/09 (H1N1), A/Wyoming/03/03 (H3N2), and A/Vietnam/1203/04 (H5N1) HALo virus. The Influenza A/Vietnam/1203/04 (H5N1) HALo mutant virus is an attenuated H5N1 virus generated from wild-type Influenza A/Vietnam/1203/04 (H5N1) virus as described in Steel, J., et al. J Virol. 2009 Feb; 83(4):1742-53. A/Wyoming/03/03 (H3N2) influenza virus replicates poorly in mice and lung tissue collected from mice inoculated with this virus did not carry viral loads detectable by plaque assay.
Project description:Whole-genome, time-course data was developed from the lungs of influenza infected mice to better characterize the dynamics of the host immune response during infection. Lung for microarray studies were obtained from female, five-week old C57BL/6Js infected with influenza viruses. Forty-two animals per group were inoculated with 10^5 PFU of A/Kawasaki/UTK-4/09 H1N1 virus [Kawasaki], A/California/04/09 (H1N1) virus (pH1N1) [SOIV], A/Vietnam/1203/04 H5N1 virus (H5N1), 10^3 PFU A/Vietnam/1203/04 H5N1 virus (H5N1) [VN1203] or mock-infected with PBS. Spanning the first week of the infections, three animals per infection group were sacrificed at 14 predetermined time points, lungs isolated and the homogenate was used to assess changes in genes expression over time and between infections.
Project description:The pathogenesis of avian influenza A H5N1 virus in human has not been clearly elucidated. There have been increasing evidence suggesting a role for virus-induced cytokine dysregulation in contributing to the pathogenesis of human H5N1 disease. However, the role of aberrant innate immune response in human lungs infected by avian influenza H5N1 virus has not been explored and direct evidence for inappropriate innate responses in lungs of avian influenza H5N1 virus infected patients is lacking. In order to obtain evidences for the proposed role of aberrant innate immune response in avian influenza H5N1 virus pathogenesis in human, we analyzed expression profile of lung tissues from two fatal cases of avian influenza H5N1 virus infected patients in comparison to normal human lung using an expression microarray.

Project description:Analysis of lung samples from mice infected with a severe H5N1 influenza virus (VN/1203/04/H5N1) or a mild H1N1 influenza virus (NYMC-X-179A) on day 3 and day 5 post-infection. Uninfected controls were used for comparison.
Project description:Periodic outbreaks of highly pathogenic avian H5N1 influenza viruses and the current H1N1 pandemic highlight the need for a more detailed understanding of influenza virus pathogenesis. To investigate the host transcriptional response induced by pathogenic influenza viruses, we used a functional-genomics approach to compare gene expression profiles in lungs from wild-type 129S6/SvEv and interferon receptor (IFNR) knockout mice infected with either the fully reconstructed H1N1 1918 pandemic virus (1918) or the highly pathogenic avian H5N1 virus Vietnam/1203/04 (VN/1203).
Project description:Comparison of the host response to VN1203 infection in three different strains of mice: Wild-type C57BL/6J mice, IDO1 KO mice and TNFRSF1B KO. Groups of 6-week-old mice were infected with A/Vietnam/1203/04 H5N1 influenza virus at a dose of 10^3 PFU or mock infected. Mice were euthanized on days 2 and 6 post-infection to measure virus load and isolate samples for measurement of virus load, lung pathology, transcriptional analysis and proteomics analysis. Mock-infected animals were also harvested at each time point. Mice were weighed every 24 hours to measure general disease progression and any mouse approaching 30% weight loss was euthanized.
