TNFRSF8 and lymphoma: As shown in Fig 5, P3HR1 tumor foci characterized by LMP1-high/ EBNA-LP-low cells (such as P3HR1 “2”) express much more CD30 in comparison to either the EBNA-LP-high/LMP1-low P3HR1 virus infected cells (such as P3HR1 “1”), or in comparison to either B95.8 or AG876 virus infected lymphoma cells with type III latency.
