Plasma Cell-Specific Transcription Factor XBP-1s Binds to and Transactivates the Epstein-Barr Virus BZLF1 Promoter
27 Sept 2007
Abstract excerpt
Epstein-Barr virus (EBV) in vivo is known to establish persistent infection in resting, circulating memory B cells and to productively replicate in plasma cells. Until now, the molecular mechanism of how EBV switches from latency to lytic replication in vivo was not known. Here, we report that the plasma cell differentiation factor, XBP-1s, activates the expression of the master regulator of EBV lytic activation,...
