Epstein-Barr virus and organophosphates – A synergistic effect in B cells?

There have been several studies investigating interactions between pesticide exposure (specifically organochlorines, organohalogens, dioxins, and dibenzofurans), non-Hodgkin’s lymphoma, and EBV antibody titres [1-4]. These studies indicate that high concentrations of chemical pesticides can interact with EBV early antigens and thus may increase the risk of development of non-Hodgkin’s lymphoma.  As most everyone is infected with EBV and many are exposed to pesticides, the potential interaction between EBV presence and pesticides mandates exploration. Could EBV predispose B cells to become tumorigenic when exposed to pesticides? This may be the case if pesticides also alter cell signaling pathways and cell cycle regulation, akin to what EBV does in cells.
