Next Generation Sequencing Facilitates Quantitative Analysis of H5N1 Wild Type and NS1-truncated Lung Transcriptomes in SPF chickens

ABSTRACT: H5N1 highly pathogenic avian influenza (HPAI) has raised global concern for causing huge economic losses in poultry industry. By using reversal genetic technical, we have rescued a H5 wild-type virus rS and its NS1-truncated virus S-NS99, harboring only 99 amino acids in the amino terminus of NS1. We then used a high-throughput RNA-seq method to analyze host and pathogen transcriptomes in the lungs of chickens infected with rS and S-NS99. Sequenced numbers of viral transcripts and expression levels of host immune-related genes at 1 day post infection (dpi) were higher in rS-infected than S-NS99-infected chickens. The numbers of immune response of rS-infected chickens by Gene Ontology (GO) enrichment were higher than S-NS99-infected chickens. KEGG pathway analysis revealed rS infection could provoke significantly stronger immune response than S-NS99. Collectively, our data provide new insight into the underlying mechanisms of the diﬀerential length NS1 of avian influenza viruses.

Genome wide host gene expression analysis in chicken lungs infected with avian influenza viruses

Project description:The mechanisms responsible for the molecular pathogenesis of the highly pathogenic avian influenza virus (HPAIV) or low pathogenic avian influenza virus (LPAIV) in avian species remain poorly understood. Thus, global immune response of chickens infected with HPAIV H5N1 (A/duck/India/02CA10/2011) and LPAIV H9N2 (A/duck/India/249800/2010) viruses was studied using microarray to identify crucial host genetic components responsive to these infection. HPAIV H5N1 induced excessive mRNA expression of cytokines (IFNA, OASL, MX1, RSAD2, IFITM5, GBP 1, IL1B, IL18, IL22, IL13, IL12B, CCL4, CCL9, CCL10, CX3CL1 etc) in lung tissues. This excessive cytokine response (cytokine storms) may cause tissue damage and high mortality in chickens. In contrast, the expression levels of most of the cytokines remained unchanged in the lungs of LPAIV H9N2 virus infected chickens. This study indicated the relationship between host cytokines response and their roles in pathogenesis in chickens infected with HPAIVs.

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.

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.

Gene expression analysis of chickens (Gallus gallus) infected with recombinant influenza viruses

Project description:H5N1 subtype highly pathogenic avian influenza virus has been spreading to Asia, Eurasia and African coutries. An original or six of recombinant H5N1 subtype influenza viruses with varying survivability were infected to chickens for elucidating genes correlated with pathogenicity. Two chickens were infected with each 10^6EID50/ head virus intranasally, and their lung was collected from infected chicken at 24 hours after infection.

Genome-wide analysis of gene expression in human macrophages in response to infection with influenza A viruses expressing full length or truncated non-structural protein NS1.

Project description:Analysis of gene expression in human macrophages infected with influenza A viruses expressing full length or truncated NS1 protein. The hypothesis tested was that C-terminal truncations of viral NS1 protein attenuate the capability of NS1 to limit activation of host antiviral and immune response genes. Cells were infected with influenza A/WSN/33 viruses expressing wild type NS1 protein (WSN-230), NS1 protein of 220 aa long (WSN-220) and NS1 protein of 202 aa long (WSN-202) on non-infected (Mock)

NS1-mediated inhibition of c-Abl results in acute lung injury and priming for bacterial co-infections; insights into 1918 H1N1 pandemic

Project description:NS1 proteins from avian influenza viruses like the 1918 pandemic NS1 are capable of inhibiting the key signaling integrator c-Abl (Abl1), resulting in massive cytopathic cell alterations. In the current study, we addressed the consequences of NS1-mediated alteration of c-Abl on acute lung injury and pathogenicity. Comparing isogenic strains that differ only in their ability to inhibit c-Abl, we observed elevated pathogenicity for the c-Abl-inhibiting virus. NS1-mediated block of c-Abl resulted in severe lung pathology and massive edema formation and facilitated secondary bacterial pneumonia. This phenotype was independent of differences in replication and immune responses, defining it as an NS1 virulence mechanism distinct from its canonical functions. Microarray analysis revealed extensive down-regulation of genes involved in cell integrity and vascular endothelial regulation. In conclusion, NS1 protein-mediated blockade of c-Abl signaling drives acute lung injury and primes for bacterial co-infections revealing potential insights into the pathogenicity of the 1918 pandemic virus. Lung transcription analysis of Influenza A virus infected mice.
