Antibody responses to Epstein-Barr virus-determined nuclear antigen (EBNA)-1 and EBNA-2 in acute and chronic Epstein-Barr virus infection.
Five distinct Epstein-Barr virus (EBV)-determined nuclear antigens (EBNA-1 to EBNA-5) were recently identified. Antibody responses to these antigens could conceivably differ, and thus prove of serodiagnostic value, in EBV-associated disease processes. As a first step, murine or human cell lines transfected with appropriate EBV DNA fragments and stably expressing either EBNA-1 or EBNA-2 were use...
متن کاملStudy of Epstein-Barr virus nuclear antigen (EBNA-1) variations: V-val type preferentially exists in biopsies of nasopharyngeal carcinoma from Vietnamese patients
Background: Epstein-barr virus nuclear antigen 1 (EBNA1) plays a crucial role in Nasopharyngeal carcinoma (NPC), the most common cancer of head and neck cancer in Asian countries with high incidents. Sequence variations are of high frequency within the functionally important domains of EBNA-1, which have been classified into five subtypes: Phenotype (P)-ala, P-thr, V-val, V-leu and V-pro and ar...
متن کاملAn Epstein-Barr virus-specific cytotoxic T cell epitope in EBV nuclear antigen 3 (EBNA 3)
Epstein-Barr virus (EBV)-specific CTL clones were isolated that recognized A-type EBV transformants but not B-type transformants. These A-type-specific CTL clones (HLA B8 restricted) were used to screen peptides derived from the EBV nuclear antigens (EBNAs) 2, 3, 4, and 6 as potential CTL epitopes. Of the 76 peptides screened, one sequence from EBNA 3 (residues 329-353) was recognized by A-type...
متن کاملThe Epstein-Barr virus-encoded nuclear antigen EBNA-5 accumulates in PML-containing bodies.
EBNA-5 is one of the Epstein-Barr virus (EBV)-encoded nuclear proteins required for immortalization of human B lymphocytes. In the nuclei of EBV-transformed lymphoblastoid cell lines EBNA-5 is preferentially targetted to distinct nuclear foci. Previously we have shown (W.Q. Jiang, L. Szekely, V. Wendel-Hansen, N. Ringertz, G. Klein, and A. Rosen, Exp. Cell Res. 197:314-318, 1991) that the same ...
متن کاملEBNA-5, an Epstein-Barr virus-encoded nuclear antigen, binds to the retinoblastoma and p53 proteins.
Epstein-Barr virus (EBV) immortalized human lymphoblastoid cell lines express six virally encoded nuclear proteins, designated EBV nuclear antigens 1-6 (EBNA-1-6). We show that the EBNA-5 protein (alternatively designated EBNA-LP) that is required for B-cell transformation can form a molecular complex with the retinoblastoma (RB) and p53 tumor suppressor proteins. Using EBNA-5 deletion mutants,...
