Epstein-Barr virus co-reconstituted with Sendai virus envelopes infects Epstein-Barr virus-receptor negative cells.

Epstein-Barr virus (EBV) was co-reconstituted with Sendai virus envelopes. The reconstituted "hybrid' virus could bind and penetrate into EBV-receptor negative cells. Using this approach, T-cell-derived human and mouse leukemia cells, human T-lymphocytes and mouse spleen cells were successfully infected as judged by the induction of EBV-determined antigens and stimulation of DNA synthesis. The T-cell-derived human leukemia line Molt-4, that can absorb EBV but without virus penetration, could be also infected by the reconstituted EBV.
