Project description:Viruses can directly interact with platelets and modulate their function. Viral impact on platelet activation, and platelet-mediated modulations of innate and adaptive immune responses. Human herpesvirus 4, also known as Epstein–Barr virus (EBV) interaction with platelets occurs via complement receptor 2 (CR2), but the exact mechanism of action with platelets is still poorly understood. Epstein–Barr virus (EBV), is extremely efficient at establishing a persistent life-long infection in human B cells. In the present study, GeneChips were performed in human platelets from three normal donors infected with the EBV-containing supernatant of the B95.8 marmoset cell line in vitro.

Project description:Most humans are infected with Epstein-Barr virus (EBV), a cancer-causing virus. While EBV generally persists silently in B lymphocytes, periodic lytic (re-)activation of latent virus is central to its life cycle and to most EBV-related diseases. However, a substantial fraction of EBV-infected B cells and tumor cells in a population is refractory to lytic activation. This resistance to lytic activation directly and profoundly impacts viral persistence and effectiveness of oncolytic therapy for EBV+ cancers. To identify the mechanisms that underlie susceptibility to EBV-lytic activation, we used host protein-expression profiling of separated-lytic and -refractory cells.

Project description:To understand epigenic dysregulation of host and viral genes upon EBV infection in human gastric cancer, genome wide transcripts by RNAseq were undertaken for total RNAs of 3 EBVnGC, their isogenic cell lines converted by in vitro EBV-infection and 3 EBV-naturally infected GC cell lines.

Project description:Epstein-Barr virus (EBV) infection of primary human B cells drives their indefinite proliferation into lymphoblastoid cell lines (LCLs). B cell immortalization depends on expression of viral latency genes as well as the regulation of host genes. Given the important role of miRNAs in regulating fundamental cellular processes, in this study we assayed changes in host miRNA expression during primary B cell infection by EBV. We observed and validated dynamic changes in several miRNAs from early proliferation through immortalization; oncogenic miRNAs were induced and tumor suppressor miRNAs were largely repressed. However, one miRNA described as a p53-targeted tumor suppressor, miR-34a, was strongly induced by EBV infection and expressed in many EBV and KSHV-infected lymphoma cell lines. The EBV latent membrane protein 1 (LMP1) was sufficient to induce miR-34a requiring downstream NFM-NM-:B activation, but independent of functional p53. Furthermore, over-expression of miR-34a was not toxic in several B lymphoma cell lines and inhibition of miR-34a impaired the growth of EBV transformed cells. This study identifies a pro-growth role for a tumor suppressive miRNA in oncogenic virus-mediated transformation highlighting the importance of studying miRNA function in different cellular contexts. miRNA expression profiling of human B-cells, EBV-infected, proliferating B cells and Monoclonal LCLs from 3 different donors was conducted with the use of up to 2 M-NM-<g total RNA for sample

Project description:Genome wide DNA methylation profiles of B cell and B cells infected with EBV (LCLs). The Illumina Infinium 27k Human DNA methylation Beadchip v1.2 was used to obtain DNA methylation profiles across approximately 27,000 CpGs in B cells and EBV infected B cells. Samples included 8 normal B cells without EBV, 8 normal B cells with EBV.
