“…This gene expression pattern is observed in lymphoproliferative disease occurring in the context of impaired cell mediated immunity, such as PTLD (Young et al, 1989). In contrast, in HL, the expression of viral proteins is restricted to EBNA1, LMP1, LMP2A and 2B, the latency II pattern of gene expression or default programme (Wu et al, 1990;Pallesen et al, 1991;Rowe et al, 1992;Deacon et al, 1993;Grasser et al, 1994;Niedobitek et al, 1997;Thorley-Lawson & Gross, 2004).…”
