Epstein-Barr virus (EBV) replicates in a latent or a lytic way in the infected organism, depending on the type and level of differentiation of the host cell. The switch between latency and lytic replication was previously shown, for Burkitt's lymphoma cell lines, to depend on the viral BZLF1 gene product. Protein-DNA assays were used to identify the(More)
The Epstein-Barr virus (EBV) immediate early gene product BZLF1 was localized by indirect immunofluorescence to the cytoplasm of the basal epithelial layer at the lateral border and dorsum of tongue in human immunodeficiency virus-infected and -seronegative patients. Two biopsies of oral hairy leukoplakia revealed a sporadic cytoplasmic staining of the(More)
The coding sequence for the hepatitis B virus surface antigen (HBsAg) was used as a new reporter gene for studies on eukaryotic promoter activity and upstream regulatory sequences. The data observed in transfection assays were comparable to results obtained with conventional chloramphenicol acetyltransferase (CAT) assays, as was demonstrated using various(More)
