Abstract
AbstractCell cultures of simian and human origin infected with two strains each of herpesvirus saimiri (HVS) and herpesvirus ateles (HVA) were compared for production of infectious virus and early and late antigens (EA, LA) in the presence and absence of the tumor promoting agent 12-O-tetradecanoylphorbol-13-acetate (TPA). Second, Epstein-Barr virus (EBV) infected human and simian lymphoblastoid cell lines of high and low cell passages were also compared for enhanced production of early antigen and virus capsid antigen (VCA) using two concentrations of TPA, owl monkey kidney (OMK) and squirrel monkey lung. Cell cultures infected with HVS and HVA with 20 ng/ml of TPA exhibited higher percentages of early and late antigen producing cells and contained 1.0-1.6 logs more virus. Such cells also had earlier cytopathic effects, larger plaques, and a 3-fold increase in the number of plaques. The TPA also enhanced HVS-EA, and LA both in OMK and human skin fibroblast (HSF) cells. The enhancement of EA was approxima...
