CD4 and Hodgkins lymphoma: However, it seems like LMP1 is sufficient to trigger CD4+ T cell recruitment, given that, in one hand, LMP1 cell counts were correlated with CD4+ cell numbers at the GC, and, on the other hand, no differences in CD4+ T cell counts were observed when LMP1 was expressed with LMP2A and/or EBNA2 at the GC, as well as in LMP1+/LMP2A+ HL cases.
