Genome-wide profiling of microRNAs revealing novel insights into mutual interactions mechanism between H9N2 avian influenza virus and avian dendritic cells

Project description:Background：Dendritic cells (DCs), have the most important antigen presenting ability and played an irreplaceable role in recognizing and clearing virus. Antiviral responses must rapidly defend against infection while minimizing inflammatory damage, but the mechanisms that regulate the magnitude of response within an infected cell are not well understood. MicroRNA, small non-coding RNAs, that can regulate dendritic cells to inhibit the infection and replication of avian influenza virus. Here, we global analyses how avian DCs response to H9N2 avian influenza virus (AIV) and provide a potential mechanism of how avian microRNA defending H9N2 AIV replication. Results： Here, we global analyses how avian DCs response to H9N2 avian influenza virus (AIV) and provide a potential mechanism of how avian microRNA defending H9N2 AIV replication. First, we found that both active and inactive H9N2 AIV enhance the ability of DCs to present antigens and activate T lymphocytes. Next, total microarray analyses suggested that H9N2 AIV stimulation involved in protein localization, nucleotide binding and leukocyte transendothelial migration and MAPK signal pathways. Moreover, we construct 551 transcription factor (TF)-microRNA-mRNA loops based on the above analyses. Furthermore, we found that HA fragment could not activate DCs, while truncated HA highly increased the immune function of DCs by activating ERK and STAT3 signal pathway. Last, our insight research not only gained that gga-miR1644 might target to MBNL2 to enhanced avian DCs in inhibiting virus replication, but also suggested that gga-miR6675 target to the NLS of PB1 to trigger the silencing of PB1 genes and lead to inhibition of H9N2 avian influenza viral replication. All together, our innovative research will shed new light on the roles of avian microRNA in evoking avian DCs and inhibiting virus replication, which will suggest new strategies to combat avian influenza virus.

Gene expression analysis of chicken dendritic cells (DCs) in response to H9N2 avian influenza virus infection

Project description:We analyze the differentially expressed genes (DEGs) at the transcriptome level in chicken DCs infected with H9N2 influenza virus compared to mock infection by high-throughput RNA-sequencing technology, and found that H9N2 influenza virus infection induced a strong innate immune response in chicken DCs, but impaired the antigen-processing and –presenting capacity of this cell,

Co-infection of H9N2 influenza A virus and Escherichia coli in a BALB/c mouse model aggravates lung injury by synergistic effects

Project description:Pathogens that cause respiratory diseases in poultry are very complicated, and co-infections with multiple pathogens are prevalent. The H9N2 strain of avian influenza virus (AIV) and Escherichia coli (E. coli) are common poultry pathogens that limit the development of the poultry industry. This study aimed to clarify the interaction between these two pathogens and their pathogenic mechanism using a mouse model. Co-infection with H9N2 AIV and E. coli significantly increased the mortality rate of mice compared to single viral or bacterial infections. It also led to the development of more severe lung lesions compared to single viral or bacterial infections. Co-infection further causes a storm of cytokines, which aggravates the host’s disease by regulating the STAT/SOCS and ERK1/2 pathways. Moreover, co-infection mutually benefited the virus and the bacteria by increasing their multiplication rates. Importantly, nitric oxide synthase 2 (NOS2) expression was also significantly enhanced by the co-infection. It played a key role in the rapid proliferation of E. coli in the presence of the coinfecting H9N2 virus. Therefore, our study underscores the role of NOS2 as a determinant for bacteria growth and illustrates its importance as an additional mechanism that enhances influenza virus-bacteria synergy. It further provides a scientific basis for investigating the synergistic infection mechanism between viruses and bacteria.

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.

A homeostasis hypothesis of avian influenza resistance in chickens

Project description:Avian influenza caused significant damages to the poultry industry, efforts have been made to reveal the disease mechanisms as well as mechanisms of disease resistance. Here, by investigating two chicken breeds with distinct responses to avian influenza virus (AIV), Leghorn GB2 and Fayoumi M43, we compared their differences in genome, methylation and transcriptome. Except for MX1 involved direct acting antiviral mechanism, we found that in both methylation and transcriptome levels the more AIV resistant breed Fayoumi showed less variations compared to White Leghorn after AIV challenging. Fayoumi also showed better consistency between the changes in methylation and changes in transcriptome level. Our results suggested a homeostasis hypothesis of avian influenza resistance, with Fayoumi better maintaining homeostasis both in epigenetic and gene expression levels.

Development of gene expression signatures for chicken LMH cells infected with infectious laryngotracheitis virus (ILTV)

Project description:To explore the molecular events in LMH cells upon infectious laryngotracheitis virus (ILTV) infection, transcriptional profiling of LMH cells infected with ILTV was compared with uninfected control cells. Gene expression in LMH cells with or without virus infection was measured at two day post infection. Four independent experiments were performed.
