Project description:Although mast cells elicit proinflammatory and type I IFN responses upon VSV infection, in response to L.monocytogenes (L.m) or S. Typhimurium (S.t), such cells elicit a transcriptional program devoid of type I IFN response. Balanced induction of proinflamatory and type I interferon (IFN) responses upon activation of Toll like receptors (TLRs) determines the outcome of microbial infections and the pathogenesis of autoimmune and other inflammatory diseases. Mast cells, key components of the innate immune system, are known for their debilitating role in allergy and autoimmune syndromes. However, their potential role in anti-microbial host defenses is increasingly being acknowledged. How mast cells interact with microbes and the nature of responses triggered thereof is not well characterized. Here we show that in response to TLR activation by Gram-positive and negative bacteria or their components like LPS, unlike macrophages, mast cells elicit pro-inflammatory but not type I IFN responses. We demonstrate that in mast cells, the bound bacteria and TLR ligands remain trapped at the cell surface and do not undergo internalization - a prerequisite for type I IFN induction. Such cells could, however, elicit type I IFNs in response to vesicular stomatitis virus (VSV), which accesses the cytosolic RIG-I receptor. Although important for anti-viral immunity, a strong type I IFN response is known to contribute to pathogenesis during bacterial infection. Thus, while endowed with the capacity to elicit type I IFNs in response to viral infection, the fact that mast cells only elicit pro-inflammatory responses upon bacterial infection illustrates that mast cells, key effector cells of the innate immune system, are well adjusted for optimal anti-bacterial and anti-viral responses. Wild type control (cntr) or interferon receptor (IFNAR)-deficient mast cells (MC) or macrophages (MAC) were infected with L.m. and S.t. (MOIs 50 and 5 for MC and MAC, respectively). MC and MAC were exposed to VSV-AV2 (MOI: 2). Samples were analyzed after 6 hours. Uninfected/unstimulated cells were used as reference samples for calculating fold change in gene expression. Gene Expression levels were determined by the Affymetrix MOE 430 2.0 GeneChips. Signal Intensities were calculated using the RMA algorithm and for statistical analysis we applied GeneSpring GX 10 software suite (Agilent Technologies, Waldbronn, Germany). MultiExperiment Viewer (MEV) software version 4.4 of the Institute for Genomic Research was used for clustering algorithm data analysis and visualization.

Project description:The purpose of this study was to determine which genes are differentially regulated virus infection in RAW264.7 cells. Cells were infected with Vesicular Stomatitis Virus (VSV) or herpes simplex virus 1 (HSV-1) for 6h. Then the differentially regulated genes were analyzed, focusing on F-box proteins and E3 ubiquitin ligases. RAW264.7 cells were infected with Vesicular Stomatitis Virus (VSV, MOI=1) or herpes simplex virus 1 (HSV-1, MOI=5) for 6h.

Project description:Previous microarray data indicated a significant increase in interferon (IFN) stimulated gene expression in cells exposed to conditioned medium from primary human trophoblasts compared to non conditioned medium. Here we want to compare the effects of conditioned media, non conditioned media, and non conditioned media spiked with 100 units of IFN beta in wild type HT1080 cells as well as in HT1080 cells deficient in STAT1 (a key signaling molecular in the IFN pathway). Interferon stimulated genes (ISGs) target viruses at various stages of their infectious life cycles, including at the earliest stage of viral entry. Here we identify ArfGAP with dual pleckstrin homology (PH) domains 2 (ADAP2) as a gene upregulated by type I IFN treatment in a STAT1-dependent manner. ADAP2 functions as a GTPase-activating protein (GAP) for Arf6 and binds to phosphatidylinositol 3,4,5-trisphosphate (PI(3,4,5)P3) and PI(3,4)P2. We show that overexpression of ADAP2 suppresses dengue virus (DENV) and vesicular stomatitis virus (VSV) infection in an Arf6 GAP activity-dependent manner, while exerting no effect on coxsackievirus B (CVB) or Sendai virus (SeV) replication. We further show that ADAP2 expression induces macropinocytosis and that ADAP2 strongly associates with actin-enriched membrane ruffles and with Rab8a- and LAMP1-, but not EEA1- or Rab7-, positive vesicles. Utilizing two techniques—light-sensitive neutral red (NR)-containing DENV and fluorescence assays for virus internalization—we show that ADAP2 primarily restricts DENV infection at the stage of virion entry and/or intracellular trafficking and that incoming DENV and VSV particles associate with ADAP2 during their entry. Taken together, this study identifies ADAP2 as an ISG that exerts antiviral effects against RNA viruses by altering Arf6-mediated trafficking to disrupt viral entry. compare the cells exposed to CM and the cells exposed to NC media spiked with IFN to the control NC exposed cells, in wild type (2f-TGH) vs Stat -/- cells (HT1080U3A)

Project description:Viral infection is commonly associated with virus-driven hijacking of host proteins. We describe a novel mechanism by which influenza virus impacts host cells through the interaction of influenza NS1 protein with the infected cell epigenome. We show that the NS1 protein of influenza A H3N2 targets the transcription elongation PAF1 complex (hPAF1C). We demonstrate that binding of NS1 to hPAF1C results in suppression of hPAF1C-mediated transcriptional elongation. More importantly,in the following data sets, we show that hPAF1 plays a crucial role in the antiviral response. Loss of hPAF1C reduces antiviral gene expression and reduces inducible transcription of target genes after stimulation with viral RNA analogue poly(I:C), vesicular stomatitis virus (VSV), exogenous recombinant IFN(beta) and influenza virus (H1N1). This study underscores the importance of hPAF1C in controlling inducible antiviral gene expression. Untreated (no siRNA), control siRNA-treated and hPAF1 siRNA-treated A549 cells were stimulated with A/Puerto Rico/8/1934 influenza virus (H1N1) or vesicular stomatitis virus (VSV). Total RNA was isolated with the Qiagen RNeasy mini kit. 200ng of total RNA per sample was used to prepare biotin-labeled RNA using MessageAmp™ Premier RNA Amplification Kit (Applied Biosystems) and hybridized to HumanHT-12 v4 Expression BeadChips (Illumina). Data analysis was performed using the GeneSpring GX11.0 software (Agilent Technologies). 3 biological replicates per condition
