Epstein-Barr virus (EBV) nuclear antigen 3C (EBNA3C) and EBNA3A are each essential for EBV conversion of primary human B lymphocytes into continuously proliferating lymphoblast cell lines (LCLs) and for maintaining LCL growth. We now find that EBNA3C and EBNA3A's essential roles are to repress p16(INK4A) and p14(ARF). In the absence of EBNA3C or EBNA3A,(More)
The production of IL-12 by macrophages/dendritic cells (Mphi/DC) is mediated either by a T cell-dependent pathway that is induced primarily by the interaction of CD40 ligand (CD40L) on activated T cells with CD40 on IL-12-producing cells or by a T cell-independent pathway that is induced by bacteria or bacterial products and enhanced by interferon-gamma(More)
To quantitatively evaluate the role of Epstein-Barr virus (EBV)-encoded latent membrane protein 2A (LMP2A) in immortalization of peripheral B-lymphocytes, we used the Akata cell system to generate an EBV recombinant in which the first exon of the LMP2A gene was disrupted. The results indicated that deletion of the LMP2A gene did not affect the(More)
Epstein-Barr virus (EBV) may cause a variety of virus-associated diseases, but no antiviral agents have yet been developed against this virus. Animal models are thus indispensable for the pathological analysis of EBV-related infections and the elucidation of therapeutic methods. To establish a model system for the study of EBV infection, we tested the(More)
