PDLIM7 and disease arising from reactivation of latent virus: Latently EBV-infected epithelial cells (which may be restricted to tumor cells in humans) have “type I” or “type II” latent infection, in which at most three latent viral proteins (EBNA1, LMP1 and LMP2A) are expressed, along with small viral nuclear RNAs and virally-encoded microRNAs [4,11].
