Abstract |
Pseudotyping lentivirus-based vectors is a strategy used to study conferred vector tropism and mechanisms of envelope glycoprotein function. Lentiviruses and filoviruses both assemble at the plasma membrane and have homotrimeric structural envelope glycoproteins that mediate both receptor binding and fusion. Such similarities help foster efficient pseudotyping. Importantly, filovirus glycoprotein pseudotyping of lentiviral vectors allows investigators to study virus entry at substantially less restrictive levels of biosafety containment than that required for wild-type filovirus work (biosafety level-2 vs. biosafety level-4, respectively). Standard lentiviral vector production involves transient transfection of viral component expression plasmids into producer cells, supernatant collection, and centrifuge concentration. Because the envelope glycoprotein expression plasmid is provided in trans, wild type or variant filoviral glycoproteins from marburgvirus or ebolavirus species may be used for pseudotyping and compared side-by-side. In this chapter we discuss the manufacture of pseudotyped lentiviral vector with an emphasis on small-scale laboratory grade production. |
