Epstein-Barr Virus Nuclear Antigen 1
Epstein-Barr virus (EBV) nuclear antigen 1 (EBNA1)--the one EBV antigen that is expressed in all EBV-associated malignancies--has long been thought to go undetected by the cell-mediated immune system. However, recent studies show that EBNA1 can be presented to both CD4+ and CD8+ T cells, making it a potential new target for immunotherapy of EBV-related cancers.
متن کاملPotential Cellular Functions of Epstein-Barr Nuclear Antigen 1 (EBNA1) of Epstein-Barr Virus
Epstein-Barr Nuclear Antigen 1 (EBNA1) is a multifunctional protein encoded by EBV. EBNA1's role in maintaining EBV in latently proliferating cells, by mediating EBV genome synthesis and nonrandom partitioning to daughter cells, as well as regulating viral gene transcription, is well characterized. Less understood are the roles of EBNA1 in affecting the host cell to provide selective advantages...
متن کاملVariations of Epstein-Barr Virus Nuclear Antigen 1 in Epstein-Barr Virus-Associated Gastric Carcinomas from Guangzhou, Southern China
Epstein-Barr virus (EBV) nuclear antigen 1 (EBNA1) is the only viral protein consistently expressed in all EBV-associated malignancies, and play a critical role in the onset, progression, and/or maintenance of these tumors. Based on the signature changes at amino acid residue 487, EBNA1 is classified into five distinct subtypes: P-ala, P-thr, V-leu, V-val and V-pro. In the present study, the se...
متن کاملU2 region of Epstein-Barr virus DNA may encode Epstein-Barr nuclear antigen 2.
Sequence analysis of the U2 regions of the B95-8 and AG876 Epstein-Barr virus (EBV) isolates reveals divergence within a long open reading frame previously identified as encoding 1.5 kilobases of the 3' end of a viral RNA expressed in latently infected, growth-transformed, B-lymphocyte cell lines. Differences among EBV isolates within the U2 open reading frame are shown to correlate with differ...
متن کاملEnhancement of hepatitis C virus replication by Epstein-Barr virus-encoded nuclear antigen 1.
Based on our recent observation that Epstein-Barr virus (EBV) is detected in 37% of the tissues of hepatocellular carcinoma, and especially frequently in cases with hepatitis C virus (HCV), the effect of EBV infection on the replication of HCV was investigated. EBV-infected cell clones and their EBV-uninfected counterparts in cell lines MT-2 (a human T-lymphotropic virus type I-infected T-cell ...
