In EBV infection most of the changes , including the early induction of cyclin D2 , are dependent on expression of EBV genes , but an alteration in the E2F-4 profile was partly independent of viral gene expression , presumably occurring in response to signal transduction activated when the virus binds to its receptor , CD21 .
