Though EBNA1 is a well-characterized protein, its role in oncogenesis is less well defined. It is consistently expressed in EBV-associated tumors. [1] EBNA1 is the only identified latent protein-encoding genes that it consistently expressed in Burkitt's lymphoma cells [6] and is believed to contribute to EBV malignancies through B cell-directed expression.
Rarely, however, a false positive heterophile antibody test may result from systemic lupus erythematosus, toxoplasmosis, rubella, lymphoma and leukemia. [7] However, the sensitivity is only moderate, so a negative test does not exclude EBV. This lack of sensitivity is especially the case in young children, many of whom will not produce ...
The Epstein–Barr virus nuclear antigen 2 (EBNA-2) is one of the six EBV viral nuclear proteins expressed in latently infected B lymphocytes is a transactivator protein. EBNA2 is involved in the regulation of latent viral transcription and contributes to the immortalization of EBV infected cells.
Epstein–Barr virus–associated lymphoproliferative diseases (also abbreviated EBV-associated lymphoproliferative diseases or EBV+ LPD) are a group of disorders in which one or more types of lymphoid cells (a type of white blood cell), i.e. B cells, T cells, NK cells, and histiocytic-dendritic cells, are infected with the Epstein–Barr virus (EBV).
The Epstein–Barr virus nuclear antigen 3 (EBNA-3) is a family of viral proteins associated with the Epstein–Barr virus. A typical EBV genome contains three such proteins: [ 1 ] EBNA-3A ( P12977 , EBNA-3; BLRF3-BERF1)
