RESUMO
Human alpha interferon (IFN) significantly inhibits the replication of herpes simplex virus type 1 in human neuroblastoma cells. This inhibitory effect can be blocked by pretreatment with antiserum to IFN. We observed no significant differences in the expression of major nucleocapsid proteins, including VP5, between IFN-treated and untreated neuroblastoma cells. Electron micrographs demonstrated that there were distinct viral nucleocapsids within IFN-treated neuroblastoma cells. The expression of glycoproteins B and E was significantly reduced in these IFN-treated cells. On the other hand, glycoprotein D, although reduced in quantity, was expressed after IFN treatment. An immunofluorescence assay of the IFN-treated and virus-infected cells detected glycoprotein D in the Golgi complexes and in the nuclear membranes. Our results indicate that human alpha IFN may be useful in the study of gene expression in IFN-treated cells of neuronal origin.
