Virus-nonproducer Raji cells, when induced to early antigen synthesis by 12-O-tetradecanoyl-phorbol-13-acetate and sodium butyrate, showed an increase in DNA polymerase activity. This enzyme has the characteristics of a typical Epstein-Barr virus DNA polymerase with regard to chromatographical pattern and biological properties: it is eluted from DEAE-cellulose at 0.08 M NaCl, has a high salt re...
Tumour tissue from 29 patients with primary brain lymphoma was reviewed to determine if there was an aetiological association between Epstein-Barr virus and polyclonal and monoclonal lymphoproliferations. The morphology and immunophenotype in 24 patients for whom paraffin wax embedded tissue was available were studied. A high grade pleomorphic tumour morphology with plasmacytoid features was se...
