title: Divergent requirements for the MAPK(ERK) signal transduction pathway during initial virus infection of quiescent primary B cells and disruption of Epstein-Barr virus latency by phorbol esters.
abstract: Quiescent primary B lymphocytes and Epstein-Barr virus (EBV)-immortalized lymphoblastoid cell lines express components of the extracellular response kinase arm of the mitogen-activated protein kinase (MAPK(ERK)) signal transduction pathway and transmit signals through the pathway when exposed to appropriate stimuli. Although the MAPK(ERK) pathway is activated following infection with EBV, MAPK/ERK kinase (MEK1) activity is not required to drive the proliferation of infected cells. However, MEK1 contributes to EBV latency control.
