Project description:When challenged with an invading pathogen, host defense mechanisms are engaged to eliminate the pathogen (resistance) and limit tissue damage that results from host-pathogen interactions (disease tolerance). We identified Arhgdia as a driver of the molecular disease-tolerance response in epithelial cells. The effect of Arhgdia on disease tolerance and resistance was evaluated at early stages of influenza A virus (IAV) infection. Our observations indicates that Arhgdia has an effect on disease tolerance during IAV infection.

Project description:We used the microarray data to analyze host cells response on A549 cells infected with Influenza A virus (A/Singapore/478/2009 (pH1N1)) The Influenza A virus (A/Singapore/478/2009 (pH1N1)) infected A549 cells were harvested at 2, 4, 6, 8 and 10 hpi and RNA extraction was performed using standard protocol as described by Affymetrix. The aim of this experiment is to analyze host response to Influenza A virus (A/Singapore/478/2009 (pH1N1)) infection.

Project description:Virus and host factors contribute to cell-to-cell variation in viral infection and determine the outcome of the overall infection. However, the extent of the variability at the single cell level and how it impacts virus-host interactions at a systems level are not well understood. To characterize the dynamics of viral transcription and host responses, we used single-cell RNA sequencing to quantify at multiple time points the host and viral transcriptomes of human A549 cells and primary bronchial epithelial cells infected with influenza A virus. We observed substantial variability of viral transcription between cells, including the accumulation of defective viral genomes (DVGs) that impact viral replication. We show a correlation between DVGs and viral-induced variation of the host transcriptional program and an association between differential induction of innate immune response genes and attenuated viral transcription in subpopulations of cells. These observations at the single cell level improve our understanding of the complex virus-host interplay during influenza infection.

Project description:Virus-host interactions are complicated processes, and multiple cellular proteins have been reported to promote or inhibit viral replication through different mechanisms. Recent progress has implicated circular RNAs (circRNA) in cancer biology and progression; however, the role of circRNAs in viral infection remains largely unclear. Here, we detected 11,620 circRNAs in A549 cells and found that 411 of them were differentially expressed in influenza virus-infected A549 cells. We characterized a novel intronic circRNA, AIVR, that was upregulated in influenza virus-infected A549 cells, and found that silencing of AIVR significantly promoted influenza virus replication in A549 cells. We further found that AIVR predominantly localizes in the cytoplasm and works as a microRNA (miRNA) sponge. One of the miRNAs absorbed by AIVR binds the mRNA of CREBBP, which is an important component of the large nucleoprotein complex IFN-β enhanceosome that accelerates IFN-β production. AIVR-overexpression significantly increased the mRNA and protein levels of INF-β in the influenza virus-infected A549 cells. Therefore, the upregulation of AIVR is a cellular antiviral strategy, with AIVR exerting its antiviral effect by absorbing miRNA and promoting the expression of CREBBP to facilitate IFN-β production. Our study provides new insights into the roles of circRNAs in the cellular innate antiviral response.

Project description:Epithelial cells are the first line of defense within the lung. Disruption of the epithelial barrier by pathogens enables the systematic dissemination of bacteria or viruses within the host, leading to severe diseases with fatal outcomes. Thus, the lung epithelium can be damaged by seasonal and pandemic influenza A viruses. Influenza A virus infection induced dysregulation of the immune system is beneficial for the dissemination of bacteria to the lower respiratory tract, causing bacterial and viral co-infection. Host cells regulate protein homeostasis and the response to different stimuli, for instance pathogen infections, by post translational modification of proteins. Aside from protein phosphorylation, ubiquitination of proteins is an essential regulatory tool in virtually every cellular process, such as protein homeostasis, the host immune response, cell morphology, and in clearing of cytosolic pathogens. Here, we analyzed the proteome and ubiquitinome of A549 cells in response to Streptococcus pneumoniae D39 Δcps and influenza A virus H1N1 as well as bacterial and viral co-infection. Pneumococcal infection induced alterations in the ubiquitination of proteins involved in the organization of the actin cytoskeleton and Rho GTPases, but had minor effects on the abundance of host proteins. H1N1 infection is reflected by an anti-viral state of A549 cells. Finally, co infection resembled the imprints of both infecting pathogens with a minor increase in the observed alterations in protein and ubiquitination abundance.
