Gene expression changes in BVDV2-infected BL3 cells

ABSTRACT: The goal of this study was to study the gene expression changes that occurred in BL3 cells that were infected with type 2 bovine viral diarrhea virus (BVDV2). What happens within the cell and how the cell responds to the virus is completely unknown. Keywords: gene expression changes, BVDV2-infected cells, acute infection This study compared the gene expression patterns in noninfected BL3 cells to that in cells that had been infected with BVDV2 for 18 hours. The 2 SAGE libraries were compared to each other to determine which transcripts were present at altered levels in the infected cells. This data will give clues to how the viral infection gives rise to the different pathologies observed in infected animals.

Human nasal epithelial cell, Influenza virus, iTRAQ

Project description:Few studies have examined the local surface remodeling of primary human nasal epithelial cells (HNECs) during viral infection. Hence, the full range of upregulated adhesion molecules during respiratory viral infections that facilitate bacterial attachment and entry remain unknown. Accordingly, the current study provides a comprehensive view of HNEC responses to influenza virus pH1N1 infection, via global proteome profiling of uninfected (Mock, n = 4) and influenza-infected (Virus-only, n = 4) HNECs with isobaric tags using relative and absolute quantitation (iTRAQ) technique. A total of 3583 proteins were detected, 89 of which were significantly increased (52 proteins) or decreased (37 proteins) in the virus-infected HNECs compared to mock-infected controls (p < 0.05).

The porcine microRNA transcriptome response to transmissible gastroenteritis virus infection

Project description:Transmissible gastroenteritis virus (TGEV; Coronaviridae family) causes huge economic losses to the swine industry. MicroRNAs (miRNAs) play a regulatory role in viral infection and may be involved in the mammalian immune response. Here, we report a comprehensive analysis of host miRNA expression in TGEV-infected swine testis (ST) cells. Deep sequencing generated 3,704,353 and 2,763,665 reads from uninfected ST cells and infected ST cells, respectively. The reads were aligned to known Sus scrofa pre-miRNAs in miRBase 19, identifying 284 annotated miRNAs. Certain miRNAs were differentially regulated during TGEV infection, which confirmed the hypothesis that specific miRNAs play a regulatory role in virus-host interactions. 59 unique miRNAs displayed significant differentially expression between the normal and TGEV-infected ST cell samples: 15 miRNAs were significantly up-regulated and 44 were significantly down-regulated. Stem-loop RT-PCR was carried out to determine the expression levels of specific miRNAs in the two samples, and the results were consistent with those of sequencing. Gene ontology enrichment analysis of host target genes demonstrated that the differentially expressed miRNAs are involved in regulatory networks, including cellular process, metabolic process, immune system process. This is the first report of the identification of ST cell miRNAs and the comprehensive analysis of the miRNA regulatory mechanism during TGEV infection, which revealed the miRNA molecular regulatory mechanisms for the viral infection, expression of viral genes and the expression of immune-related genes. The results presented here will aid research on the prevention and treatment of viral diseases. 2 ST(Porcine testicular cells) cell samples, ST: normal ST cell sample (contro sample), TGEV: TGEV (Transmissible gastroenteritis virus) infected ST cell samples

PRRSV-infection of porcine alveolar macrophages

Project description:The goal of this study was to produce a deep, global analysis of gene expression changes that occured following infection of normal porcine alveolar macrophages (PAMs) with PRRSV. The goal was to examine the gene expression changes to help determine the mechanisms that result in reduced function and immunosuppression observed in PRRSV-infected pigs. Keywords: time course of infection The PAMs were infected in culture at an MOI of 10 with PRRSV strains VR-2332 and incubated at 37C until 6, 12, 16 or 24 hours post infection. Total cellular RNA was collected from each at the appropriate time. SAGE libraries were prepared from each infected time point as well as from noninfected PAMs. The SAGE libraries were sequenced to at least 95,000 tags each.

Small RNA deep sequencing identifies viral microRNAs during malignant catarrhal fever induced by alcelaphine herpesvirus 1

Project description:Alcelaphine herpesvirus 1 (AlHV-1) is a ?-herpesvirus (?-HV) carried asymptomatically by wildebeest. Upon cross-species transmission, AlHV-1 induces an acute and fatal lymphoproliferative disease named malignant catarrhal fever (MCF) in many ruminants, including cattle and the rabbit model. Latency has been shown to be essential for MCF induction. However, the mechanisms causing the activation and proliferation of infected CD8+ T cells are unknown. Many ?-HVs express microRNAs (miRNAs). These small noncoding RNAs can suppress host or viral target genes involved in various pathways and are thought to facilitate viral infection and/or mediate activation and proliferation of infected lymphocytes. AlHV-1 genome has been predicted to encode a large number of miRNAs. However, their precise contribution in viral infection and pathogenesis in vivo remains unknown. Here, we have cloned small RNAs and sequenced 36 potential miRNAs expressed in a lymphoblastoid cell line propagated from a calf infected with AlHV-1 and developing MCF. Among the sequenced candidate miRNAs, 32 were expressed on the reverse strand of the genome in two main clusters. The expression of these 32 viral miRNAs was further validated using Northern blot and qRT-PCR in lymphoid organs of MCF-developing calves or rabbits. To determine the concerted contribution in MCF of 28 viral miRNAs clustered in the non-protein-coding region of the AlHV-1 genome, a recombinant virus was produced. The absence of these 28 miRNAs did not affect viral growth in vitro nor MCF induction in rabbits, demonstrating that AlHV-1 miRNAs clustered in the non-protein-coding genomic region are not essential for MCF induction.

The majority of viral peptides displayed on class I MHC are immunogenic during infection

Project description:CD8+ T cells are essential effectors in anti-viral immunity, recognising short virus-derived peptides presented by MHC class I (pMHCI) on the surface of infected cells. However, the fraction of viral pMHCI on infected cells that are immunogenic has not been shown for any virus. To approach this fundamental question, we used peptide sequencing by high-resolution mass spectrometry to identify nearly 200 vaccinia virus pMHCI presented on infected mouse cells. Next, we screened each peptide for immunogenicity in multiple virus-infected mice, revealing a wide range of immunogenicities. A surprisingly high fraction (>80%) of pMHCI were immunogenic at least one infected animal and around half of these were dominant, which we define as being immunogenic across more than half of the mice screened. The high number of peptides found to be immunogenic and the variability in immunogenicity across mice give us new insight into the specificity of anti-viral CD8+ T cell responses.

Hernandez-Vargas2012 - Innate immune system dynamics to Influenza virus

Project description:A. Esteban Hernandez-Vargas & Michael Meyer-Hermann. Innate Immune System Dynamics to Influenza Virus. IFAC Proceedings Volumes 45, 18 (2012). The understanding of how influenza virus infection activates the immune system is crucial to designing prophylactic and therapeutic strategies against the infection. Nevertheless, the immune response to influenza virus infection is complex and remains largely unknown. In this paper we focus in the innate immune response to influenza virus using a mathematical model, based on interferon-induced resistance to infection of respiratory epithelial cells and the clearance of infected cells by natural killers. Simulation results show the importance of IFN-I to prevent new infections in epithelial cells and to stop the viral explosion during the first two days after infection. Nevertheless, natural killers response might be the most relevant for the first depletion in viral load due to the elimination of infected cells. Based on the reproductive number, the innate immune response is important to control the infection, although it would not be enough to clear completely the virus. The effective coordination between innate and adaptive immune response is essential for the virus eradication.
