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:We describe how the cancer-causing Epstein-Barr virus (EBV), a prototypic herpesvirus, alters proteome at viral replication forks prominently identifies chromatin modifying and transcriptional repression proteins. Specifically, to transition from transcription, the viral DNA polymerase processivity factor EA-D is SUMOylated by the transcriptional corepressor KAP1-TRIM28. KAP1 function is triggered by phosphorylation via the PI3K-related kinase ATM and the helicase RECQ5 at the transcription machinery. SUMO-EA-D recruits the histone loader CAF1 and the methyltransferase SETDB1 to silence the parental genome, prioritizing replication. Thus, DNA repair, epigenetic, and transcription-replication interference pathways orchestrate the handover from transcription to replication, a fundamental feature of DNA viruses

Project description:Soluble ectodomains of Epstein Barr Virus glycoproteins gH/gL and gp42 were expressed in HEK293F cells for structural characterization by cryo electron microscopy. The purified material was additionally analyzed by LC-MS/MS after digestion with trypsin or chymotrypsin to identify N-linked glycosylation from EThcD glycopeptide fragmentation spectra.

Project description:Epstein-Barr virus (EBV) Rta is a latent-lytic molecular switch evolutionarily conserved in all gamma-herpesviruses. In previous studies, doxycycline-inducible Rta was shown to potently produce an irreversible G1 arrest followed by cellular senescence in 293 cells. Here, we demonstrate that in this system the inducible Rta not only reactivates resident genome of EBV but also that of Kaposi’s sarcoma-associated herpesvirus (KSHV), to similar efficiency. However, Rta-induced senescence program was terminated by the robust viral lytic cycle replication that eventually caused cell death. Furthermore, prior to the abrupt expression of immediate-early protein (EBV BZLF1 or KSHV RTA), Rta simultaneously down-regulates cell cycle activators (c-Myc, CDK6, CCND2) and up-regulates senescence-related genes (p21, 14-3-3s). Since Rta is a viral immediate-early transcriptional activator, it is envisioned that during the initial stage of viral reactivation, Rta may engage to modulate the host transcriptome, to halt cell cycle progression, and to maintain an ideal environment for manufacturing infectious virions. Refer to individual Series. This SuperSeries is composed of the following subset Series: GSE24585: Expression profiling of host genes modulated by Epstein-Barr virus (EBV) Rta in HEK293 cells GSE24586: Expression profiling of host genes modulated by Epstein-Barr virus Rta in nasopharyngeal carcinoma cells

Project description:The immediate-early protein BRLF1 plays important roles in lytic infection of Epstein-Barr virus (EBV), in which it activates lytic viral transcription and replication. However, knowledge of the influence of BRLF1 on cellular gene expression and transcriptional reprogramming during the early lytic cycle remains limited. Analysis of BRLF1-binding proteins by mass spectrometry would show what transcription factors BRLF1 binds to and would help us better understand how BRLF1 regulates human and viral genome during lytic infection.

Project description:Comparsion of cellular gene expression between a control B lymphoma cell-line (BJAB pz2) stably transfected with an empty vector and a BJAB cell-line stably expressing Epstein-Barr virus EBNA 3C (BJAB E3C-4). These cell lines are described in Wang, F., C. Gregory, C. Sample, M. Rowe, D. Liebowitz, R. Murray, A. Rickinson, and E. Kieff. 1990. Epstein-Barr virus latent membrane protein (LMP1) and nuclear proteins 2 and 3C are effectors of phenotypic changes in B lymphocytes: EBNA-2 and LMP1 cooperatively induce CD23. J Virol 64:2309-2318)

Project description:Epstein-Barr virus is associated with several human malignancies, including Burkitt Lymnphoma. The virus encodes more than 40 microRNAs, which participate in its possible pathogenetic role. We used microarrays to study the effect of the expression of an Epstein-Barr virus-encoded microRNA (ebv-BART6-3p) on the global gene expression profile of Burkitt Lymphoma cell lines.

Project description:Epstein Barr virus causes linfectious mononucleosis and establishes lifelong infection associated with cancer and autoimmune disease. To better understand immunity to EBV, we performed a prospective study of natural infection in healthy humans. These anlyses were undertaken in order to determine what gene expression changes occur as the result of primary Epstein Barr virus infection. Samples were taken both before and following acquisition of the virus for direct comparison of samples for single subjects. These data provide an important first description of the response to natural herepesvirus infection in humans. PBMC were taken before acquisition of EBV, during acute infection, and during latency
