摘要

We describe the generation of lentiviruses pseudotyped with human parainfluenza type 3 envelope(HPIV3)glycoproteins.Lentivirus particles,expressed in 293T/17 cells,incorporate HPIV3 hemagglutinin-neuraminidase(HN)and fusion(F)proteins into their lipid bilayers and are able to transduce human kidney epithelial cells and polarized MDCK cells.Nfturaminidase,AZT,and anti-HPIV3 antisera block trans-duction,which is consistent with lentiviral-mediated transduction via sialated receptors for HPIV3.Our findings show that HPIV3 pseudotyped lentiviruses can be formed and may have a number of useful properties for human gene transfer.
