Macrophages derived from human peripheral blood and cultured for 1 week were permissive for the replication of herpes simplex virus (HSV) types 1 and 2. Low titers of interferon (IFN) were produced after virus infection. The yield of infectious virions was reduced by pretreatment of cells with natural and recombinant IFN-alpha and natural IFN-beta. Recombinant and natural IFN-gamma exhibited very low antiviral activity. Treatment of cells with IFN-gamma mixed with IFN-alpha or with IFN-beta did not result in a synergistic inhibition of virus yield. We studied the synthesis of HSV type 1- and HSV type 2-coded proteins in macrophages treated with IFN-beta. Induction of the HSV beta-protein DNA polymerase was strongly inhibited in IFN-treated cells in a dose-dependent manner. As shown by sodium dodecyl sulfate-polyacrylamide gel electrophoresis, other beta- and gamma-proteins of HSV were inhibited as well. Immunofluorescence studies revealed a strong inhibition of the expression of immediate early alpha-protein ICP4. The results indicate that IFN acts early during the viral replication cycle to inhibit the synthesis of HSV alpha- and beta-proteins.
