Project description:To study miRNA expression profiles during highly pathogenic avian influenza virus infection, we conducted global miRNA expression profiling in human lung epithelial cells (A549) with or without H5N1 IAV infection. .
Project description:To further understand the roles of miRNA during influenza A virus infection, we performed miRNA profiling in human alveolar adenocarcinoma cell lines, A549 cells, infected with influenza A virus A/Beijing/501/2009(H1N1) and A/goose/Jilin/hb/2003(H5N1).
Project description:Ducks and wild aquatic birds are the natural reservoirs of avian influenza viruses. However, the host proteome response that causes disease in vivo during infection by the highly pathogenic avian influenza (HPAI) H5N1 virus is still not well understood. In the present study, we compared the proteome response in Muscovy duck lung tissue during 3 day of infection with either a highly virulent or an avirulent H5N1 virus. During infection, proteins involved in immune response of neutrophils and size of cells were increased markedly in the lung by the virulent strain, while the avirulent strain evoked a distinct response, characterized by an increase in proteins involved in cell movement, maturation of dendritic cells, adhesion of phagocytes, and immune response of macrophages.
Project description:Human tracheobronchial epithelial (HTBE) cells are considered to serve as a good correlate of influenza virus infection in the human respiratory tract. mRNA-Seq analysis was used to profile the cellular transcriptome of HTBE cells 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.
Project description:Human tracheobronchial epithelial (HTBE) cells are considered to serve as a good correlate of influenza virus infection in the human respiratory tract. ChIP-Seq analysis was used to profile histone acetylation (H3K27ac) in HTBE cells 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.
Project description:Hi-C was used to profile changes in the genome structure of human primary cells at multiple time points in response to infection with active and UV-inactivated H5N1 influenza virus. Human tracheobronchial epithelial cells (HTBE) and monocyte-derived macrophages (MDM) were used. 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.

Project description:MiRNA profiling in lung epithelial cells during infection with influenza A virus
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:Current prophylactic and therapeutic strategies targeting human influenza viruses include vaccines and antivirals. Given variable rates of vaccine efficacy and antiviral resistance, alternative strategies are urgently required to improve disease outcomes. Here we describe the use of HiSeq deep sequencing to analyze host gene expression in primary human alveolar epithelial type II (ATII) cells infected with highly pathogenic avian influenza H5N1 virus. We employed primary human ATII cells isolated from normal human lung tissue donated by patients that underwent lung resection. Human host gene expression following HPAI H5N1 virus (A/Chicken/Vietnam/0008/04) infection of primary ATII cells was analyzed using Illumina HiSeq deep sequencing.
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.
