Epstein-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 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...
متن کاملImmortalization of human lymphocytes by Epstein-Barr virus.
Epstein-Barr virus (EBV) confers upon normal lymphocytes derived from bone marrow the ability to proliferate indefinitely in a test tube. This process, called immortalization, is crucial to the pathogenesis of EBV infections. Inside the immortalized lymphocyte the EBV genome exists as a complete multicopy circular plasmid which is probably not integrated into the cell chromosome. Most of the vi...
متن کاملMetabolic stress is a barrier to Epstein-Barr virus-mediated B-cell immortalization.
Epstein-Barr virus (EBV) is an oncogenic herpesvirus that has been causally linked to the development of B-cell and epithelial malignancies. Early after infection, EBV induces a transient period of hyperproliferation that is suppressed by the activation of the DNA damage response and a G1/S-phase growth arrest. This growth arrest prevents long-term outgrowth of the majority of infected cells. W...
متن کاملContributions of the EBNA1 Protein of Epstein-Barr Virus Toward B-Cell Immortalization and Lymphomagenesis
Epstein-Barr Virus (EBV) is a human herpesvirus, infecting 95% of humans, that is causally associated with the benign B-cell proliferative disorder, infectious mononucleosis. EBV has also been etiologically associated with several cancers, such as Burkitt's lymphoma, AIDSrelated immunoblastic lymphomas, post-transplant lymphomas, nasopharyngeal carcinoma, and gastric carcinoma. Very few viral g...
