The ΔEBNA2 + Myc lymphomas also express the GC marker CD10 (MME), while ΔEBNA2 lymphomas have higher expression of CD30 (a B cell activation marker), BLIMP1 (PRDM1, a marker for plasma cell differentiation) and BZLF1 (a lytic EBV protein) in comparison to ΔEBNA2 + Myc lymphomas (Figs 2D and 3A). The gene discussed is PRDM1; the disease is lymphoma.
