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.

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.

Differential expression data of BMDMs of mice infected with avian influenza influenza A (H7N9) viruses

Project description:To clarify the underlying mechanism that regulates the response of iron metabolism to influenza A virus infection, we analyzed gene expression profiles in mouse, bone marrow-derived macrophages (BMDMs) infected with H7N9 virus. In addition, We also analysed the chemokine, inflammation, innate-immunity, lipid-metabolism, transcription mRNA level by micrroarray. So, we gain the global transcriptional response in the BMDMs of mice infected with H7N9 virus.

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.

Pathogenesis of influenza A(H7N9) virus in aged non-human primates

Project description:The avian influenza A(H7N9) virus has caused high mortality in humans, especially in the elderly; however, little is known about the mechanistic basis for this. In this study, we employed non-human primates to evaluate the effect of aging on the pathogenicity of A(H7N9) virus. We observed that A(H7N9) virus infection of aged animals (defined as 20–26 years) caused more severe symptoms than infection of young animals (defined as 2 3 years). In aged animals, lung inflammation was weak and virus infection was sustained. Although cytokine and chemokine expression in the lungs of most aged animals was lower than that in the lungs of young animals, one aged animal showed dysregulated proinflammatory cytokine and chemokine production, resulting in it being euthanized. These results suggest that attenuated or dysregulated immune responses in aged animals are responsible for the severe symptoms observed among elderly patients infected with A(H7N9) virus.

Cynomolgus macaque model of H7N9 influenza infection

Project description:The objective of this study is to characterize the response to newly emerged, highly pathogenic H7N9 influenza virus isolated from human patients in 2013 in China. This study examines the pathogenesis of H7N9 influenza in cynomolgus macaques. The study compares lung lesions to adjacent right lower lobe lung tissue in animals necropsied at days 3 and 6 post-infection (n=4 animals/timepoint). 3-4 lesions from each animal were collected and equal amounts of pooled RNA from lesions from individual animals at each time point were used for microarray.
