EGCG, a polyphenol in green tea, has shown in a study to inhibit EBV spontaneous lytic infection at the DNA, gene transcription, and protein levels in a time- and dose-dependent manner; the expression of EBV lytic genes" Zta, Rta", and early antigen complex EA-D (induced by "Rta"), however, the highly stable "EBNA-1" gene found across all stages of EBV infection is unaffected. Specific inhibitors (to the pathways) suggest that Ras/MEK/MAPK pathway contributes to EBV lytic infection though BZLF1 and PI3-K pathway through BRLF1, the latter completely abrogating the ability of a BRLF1 adenovirus vector to induce the lytic form of EBV infection. Additionally, the activation of some genes but not others is being studied to determine just how to induce immune destruction of latently infected B-cells by use of either TPA or sodium butyrate.
