PDLIM7 and nasopharyngeal carcinoma: Nevertheless, since at least three different EBV proteins (EBNA1, LMP1 and LMP2A) are expressed in both HL and NPC [55, 56], and LMP1 expression in particular has been shown to promote T cell-mediated killing [57–60], a number of studies have investigated the potential mechanism(s) by which T cell-mediated killing of EBV-infected tumor cells might be inhibited in these tumors.
