Transcriptomic expression profiles of SPF chicken-spleen infected with duck-origin H7N9 subtype avian influenza virus and fowl adenovirus-4

Project description:With the purpose to elucidate the expression changes of host genes of SPF chickens infected with duck-origin H7N9 subtype avian influenza virus at 24 hours post-infection(hpi) and fowl adenovirus-4 at 48 dpi. The spleens of SPF chickens infected with duck-origin H7N9 subtype avian influenza virus and fowl adenovirus-4 were collected and high throughout sequenced. Compared with the control group, there were 2426 differentially expressed genes were obtained in the duck-origin H7N9 subtype avian influenza virus group, including 913 up-regulated genes and 1513 down-regulated genes, and there were 1534 differentially expressed genes were obtained in the fowl adenovirus-4 group, including 632 up-regulated genes and 902 down-regulated genes.

Transcriptomic expression profiles of SPF chicken-lung infected with duck-origin H7N9 subtype avian influenza virus

Project description:In order to elucidate the expression changes of host genes of SPF chickens infected with duck-origin H7N9 subtype avian influenza virus. The lungs of SPF chickens infected with duck-origin H7N9 subtype avian influenza virus were collected and high throughout sequenced. Compared with the control group, there were 740 differentially expressed genes were obtained in infection group, including 602 up-regulated genes and 138 down-regulated genes. The analysis of the GO items showed that the differentially expressed genes were involved in immune responses and inflammatory responses. The results of KEGG analysis showed that 7 pathways were enriched significantly, in those the Toll-like pathway had 11 up-regulated genes, namely IL-6, TLR4, Pik3, IRF7, MD-2, IRF5, MYD88, CD86, STAT1, TLR2, and CCL4. There were 7 up-regulated genes in NOD-like receptor signaling pathway, which were IRF7, CTSB, P2RX7, CYBB, PSTPIP1, HSP90AA1, and NAMPT. In Toll-like signaling pathway，TLR4 was activated by MD-2 after viral infection, and then activated downstream IRF5. At the same time, the NLRP3 inflammasome also played an important role in the process of H7N9 virus infection.

Transcriptomic characterization of the novel avian-origin influenza A (H7N9) virus: specific and intermediate host-response between avian (H5N1 and H7N7) and human (H3N2) viruses.

Transcriptomic characterization of the novel avian-origin influenza A (H7N9) virus: specific and intermediate host-response between avian (H5N1 and H7N7) and human (H3N2) viruses.

Project description:A novel avian-origin H7N9 influenza A virus (IAV) emerged in China in early 2013 causing mild to lethal human respiratory infections. H7N9 originated from multiple reassortment events between avian viruses and carries genetic markers of human adaptation. Determining whether H7N9 induces a host-response closer to human or avian IAV is important to better characterize this emerging virus. Here we compared the human lung epithelial cell response to infection with A/Anhui/01/13 (H7N9) or highly pathogenic avian-origin H5N1, H7N7, or human seasonal H3N2 IAV. Here, polarized confluent monolayers of Calu-3 cells were infected apically with the avian-origin IAVs A/Anhui/01/2013 (H7N9) [Anhui01], A/Netherland/219/2003 (H7N7) [NL219], A/Vietnam/1203/2004 (H5N1) [VN1203], or a human seasonal virus A/Panama/2007/1999 (H3N2) [Pan99] at an MOI of 1. Time-matched mocks were also included using the same cell stock as the rest of the samples. Culture medium (same as what the virus stock is in) was used for the mock infections. Quadruplicate wells were infected for each virus/timepoint. Measured timepoints were 3, 7, 12 and 24 hours post-inoculation and the RNA was used for transcriptional analysis via microarray.

Transcriptional profile from peripheral blood in patients infected with avian influenza H7N9 virus

Project description:Avian influenza A (H7N9) viruses have emerged in China in 2013 and caused zoonotic disease associated with a case-fatality ratio of over 30%. Transcriptional profile from peripheral blood has been shown to reflect host responses against a specific respiratory pathogen and can be used to understand the disease. Methods: We correlated the clinical data and blood transcriptomic profile of patients with avian influenza A (H7N9) disease and determined the biological significance of the infection from the analysis.

Expression data from low- and high-pathogenicity avian influenza-infected chicken and duck cells

Project description:While infection of chickens with highly pathogenic avian influenza (HPAI) H5N1 subtypes often leads to complete mortality within 24 to 48 h, infection of ducks in contrast causes mild or no clinical signs. Rapid onsets of fatal disease in chickens, but with no evidence of severe clinical symptoms in ducks, suggest underlying differences in their innate immune mechanisms. To understand the molecular basis for such difference, chicken and duck primary lung cells, infected with a low-pathogenicity avian influenza (LPAI) and two HPAI H5N1 viruses, were subjected to RNA expression profiling using Affymetrix Chicken GeneChip arrays. We used microarrays to analyze the gene expression profiles of primary chicken and duck lung cells infected with H2N3 LPAI and two H5N1 influenza virus subtypes to understand the molecular basis of host susceptibility and resistance. We have identified a set of key genes and pathways that could play an important role in mediating innate host resistance to avian influenza in chickens and ducks.

Quantitative proteomic analysis of duck lung tissue during infection of avian influenza

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.
