Abstract
Inducers of the Epstein-Barr virus (EBV) cycle, 5-iodo-2-deoxyuridine (IdUrd), phorbol myristate acetate (TPA) and sodium butyrate were tested for their ability to induce EBV-determined antigens, early antigen (EA) and virus capsid antigen (VCA), and to stimulate interferon (IF) production in a variety of EBV-carrying lymphoid cell lines. IdUrd and TPA induced IF production to various extents in the different lines, whereas sodium butyrate did not. There was no relationship between induction of the EBV cycle and production of IF; the two appear to be independent characteristics.
