Gene expression in IRF3-/- peritoneal macrophage infected with VSV

ABSTRACT: IRF3 is one of the most critical transcription factor in down stream of pattern recognition receptors (such as toll-like receptor and RIG-I-like receptor) signalling pathway. IRF3 is known to induce the expression of type I IFN gene upon virus infection. To furter examine the role of IRF3 in virus-induced gene expression, we preformed microarray analysis in IRF3-/- peritoneal macrophages infected with VSV, and found that IRF3 suppresses the expression of Il12b gene.

To furter examine the role of IRF3 in virus-induced gene expression, we preformed microarray analysis in IRF3-/- peritoneal macrophages infected with VSV, and found that IRF3 suppresses the expression of Il12b gene. Peritoneal macrophages from WT of IRF3-/- B6 mice were infected with VSV(1 M.O.I. ) for 6 hous, and then subjected to microarray analysis.

miRNA profiling of mouse primary peritoneal macrophages infected with vesicular stomatitis virus (VSV)

Project description:To investigate whether and what miRNAs expression might be regulated by VSV (vesicular stomatitis virus?) challenge, we analyzed the miRNA expression profile of mouse primary peritoneal macrophages infected with VSV by using an array-based miRNA profiling. After the infection of VSV at MOI 10 for 48 h, the array revealed that many miRNAs were up-regulated in macrophages?

Gene expression from splenic cells in response to VSV-M2 and ligands to RIG-I and MDA5

Project description:VSV-M2 is recognized by cytosolic RIG-I. Notably, 5'-triphosphate RNA molecules derived from either viral RNA or from the synthetically produced 3pRNA can also induce RIG-I activation. MDA5 stimulation is achieved using complexed poly(I:C), a synthetic analog of viral dsRNA. To test whether the RIG-I and MDA5 ligands 3pRNA and poly(I:C) can be used in their complexed structures to decipher RNA virus-induced sickness behavior in vivo, we first compared the tissue-specific signaling pathways after systemic challenge with VSV-M2 and the RIG-I and MDA5 ligands, respectively. A whole-genome expression analysis using splenic cells was carried out using an Affymetrix Mouse Gene 2.1 ST Array.

diaPASEF and DIA of proteome and phosphoproteome of VSV-stimulated THP1 cells

Project description:Infection of mammalian cells by vesicular stomatitis virus (VSV) triggers the activation of the innate immunity pathway. VSV RNA is recognized by RIG-I, leading to the activation of RIG-I and subsequent activation of the essential effector MAVS. To gain a comprehensive understanding of the molecular events occurring in VSV-infected THP1 cells, we employed data-independent acquisition (DIA) and diaPASEF techniques to profile the dynamic phosphoproteomes and proteomes of wild-type (WT), RIG-I knockout (KO), and MAVS KO THP1 cells. This approach enabled the quantification of approximately 8000 proteins and 11000 localized phosphopeptides. The in-depth proteomic and phosphoproteomic analyses provided insights into the molecular mechanisms underlying VSV-induced ATM-mediated PBX2 degradation. Moreover, the phosphoproteomic data revealed that VSV induces phosphorylation events in THP1 cells independently of RIG-I. Additionally, we identified five phosphosites on VSV-coding proteins and predicted the corresponding kinases in host cells. Overall, our findings offer a comprehensive proteomic and phosphoproteomic map of VSV stimulation, highlighting RIG-I or MAVS-related phosphorylation events. This resource serves as a valuable foundation for future studies aimed at understanding the RNA-sensing innate immunity signaling pathway.

Irf3 phenotyping

Project description:The interferon regulatory factors IRF3 and IRF7 are key players in the regulation of type I and III IFN genes. In this study, we analyzed the role of IRF3 and IRF7 for the host response to influenza A virus infections in Irf3-/-, Irf7-/- and Irf3-/-Irf7-/- knock-out mice.

Gene expression in HeLa cells expressing GFP-IRF3 (non-targeting control and clonal knockouts of DDX58, MAVS, ATP13A1, CAPN15, TADA2B, MED16, and MED24) following Sendai virus (SeV) infection or hpRNA transfection

Project description:IRF3 translocates from the cytoplasm to the nucleus upon recognition of a cytoplasmic RNA stimulus by RIG-I or MDA5. Using an optical pooled CRISPR knockout screen in HeLa-Cas9 cells, we identified ATP13A1, CAPN15, TADA2B, MED16, and MED24 as novel genes affecting the translocation of IRF3 upon Sendai virus infection. We generated isogenic clonal knockout HeLa-Cas9 lines and confirmed that loss of these five novel genes results in either decreased (ATP13A1 and CAPN15) or increased (TADA2B, MED16, and MED24) translocation of IRF3 upon Sendai virus or synthetic hpRNA stimulation.

Macropahge-specific Irf3 prevents viral inflammation

Project description:Viral inflammation contributes to pathogenesis and mortality during respiratory virus infections. We recently uncovered Irf3, a critical component of innate antiviral immune responses, interacts with pro-inflammatory transcription factor NF-kB, and inhibits its activity. Irf3, using this mechanism, suppresses inflammatory gene expression in virus-infected cells and mice. In this study, we evaluated the cells responsible for Irf3-mediated suppression of viral inflammation using newly engineered conditional Irf3Δ/Δ mice. Irf3Δ/Δ mice, upon respiratory virus infection, showed increased susceptibility and mortality. Irf3 deficiency caused enhanced inflammatory gene expression, lung inflammation, immunopathology, and damage, which were accompanied by increased infiltration of pro-inflammatory macrophages. Deletion of Irf3 in macrophages (Irf3-MKO) displayed, similar to Irf3Δ/Δ mice, increased inflammatory responses, macrophage infiltration, lung damage, and lethality, indicating Irf3 in these cells suppressed lung inflammation. RNA-seq analyses revealed enhanced NF-kB-dependent gene expression along with activation of inflammatory signaling pathways in infected Irf3MKO lungs. Targeted analyses revealed activated MAPK signaling in Irf3MKO lungs. Therefore, Irf3 inhibited inflammatory signaling pathways in myeloid cellsmacrophages to prevent viral inflammation and pathogenesis.

RNA transcriptome analysis of IRF1 and IRF3 knockout in immortalized primary hepatocytes infected with hepatitis A virus

Project description:Interferon regulatory factors (IRFs) play key roles in the transactivation of antiviral genes at the step downstream of activated pathogen-associated molecular pattern sensors, such as RIG-I-like receptors or Toll-like receptors. Whereas IRF1 and IRF3 are thought to bind similar DNA elements (ISRE and PRD-III, PRD-I) to activate antiviral gene transcription, genome-wide transcriptome profiling of IRF1 versus IRF3 knockouts in an immortalized primary hepatocyte (PH5CH8) cell line infected with hepatitis A virus (HAV) revealed unexpected disparities in their target genes. IRF1 targets include several anti-HAV effector genes that were not previously recognized to have antiviral functions.

Gene expression in RAW264.7 cells infected with VSV and HSV-1

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. Equal amounts of RNA were assayed for gene expression using Affymetrix mouse 430 2.0 arrays.
