Promoter sequences required for reactivation of Epstein-Barr virus from latency.
A luciferase reporter system with stably transfected oriP plasmids in Akata Burkitt's lymphoma cells provides a quantitative assay for the BZLF1 Zp promoter in response to B-cell receptor (BCR) activation by cross-linking with anti-immunoglobulin. In this system, detailed kinetic studies of promoter activity are possible. Previously reported promoter elements upstream of -221 from the transcrip...
متن کاملEpigenetic modification of the Epstein-Barr virus BZLF1 promoter regulates viral reactivation from latency
The Epstein-Barr virus (EBV) is an oncogenic human gamma-herpesvirus that predominantly establishes latent infection in B lymphocytes. Viral genomes exist as extrachromosomal episomes with a nucleosomal structure. Maintenance of virus latency or execution of reactivation is controlled by the expression of BZLF1, a viral immediate-early gene product, tightly controlled at the transcriptional lev...
متن کاملEpstein-Barr virus immortalization and latency.
Epstein-Barr virus infects human B lymphocytes. The interaction between the virus and these cells has been the subject of investigation for over three decades. Recent in vitro and in vivo studies, reviewed here, are revealing the mechanisms by which EBV induces and controls proliferation through the expression of six viral nuclear proteins and two plasma membrane proteins. This genetic program ...
متن کاملFatal hepatitis during Epstein-Barr virus reactivation.
Fulminant hepatitis by Epstein-Barr virus is a rare event which is predominantly due to primary infection. We report a rare case of fatal hepatic failure due to Epstein-Barr virus reactivation in a 19-year-old boy who was taking oral steroids. Transaminase peak and the fulminant course of the disease began soon after steroid interruption. Epstein-Barr virus reactivation was diagnosed on the bas...
متن کاملTHE IN VITRO GROWTH PROPERTIES OF CELL LINES FROM EPSTEIN-BARR VIRUS-INDUCED TAMARIN TUMORS AND TAMARIN B CELLS TR ANSFORMED BY EPSTEIN BARR VIRUS
EBV-carrying human cell lines, depending on whether the cells are derived from Burkitt's lymphoma (BL) tumor biopsies or transformed by EBV in vitro, have different growth properties in vitro. In contrast, there are no clear differences between tamarin tumor lines and tamarin LCLs in vitro. Both types of tamarin cell lines could grow in agarose and formed colonies unlike human LCLs, althoug...
