RESUMO
Epstein-Barr virus (EBV) is a strict human pathogen for which no small animal models exist. Plasmids that contain the EBV plasmid origin of replication, oriP, and express EBV nuclear antigen 1 (EBNA1) are stably maintained extrachromosomally in human cells, whereas these plasmids replicate poorly in rodent cells. However, the ability of oriP and EBNA1 to maintain the entire EBV episome in proliferating rodent cells has not been determined. Expression of the two human B-cell receptors for EBV on the surfaces of murine B cells allows efficient viral entry that leads to the establishment of latent EBV infection and long-term persistence of the viral genome. Latent gene expression in these cells resembles the latency II profile in that EBNA1 and LMP1 can be detected whereas EBNA2 and the EBNA3s are not expressed.
