PEGylation of a vesicular stomatitis virus G pseudotyped lentivirus vector prevents inactivation in serum.

Inactivation in Serum G Pseudotyped Lentivirus Vector Prevents PEGylation of a Vesicular Stomatitis Virus

Human immunodeficiency virus type 1-derived lentivirus vectors pseudotyped with envelope glycoproteins derived from Ross River virus and Semliki Forest virus.

Ross River virus (RRV) and Semliki Forest virus (SFV) are two alphaviruses that have a high degree of amino acid homology, as well as a very broad host range. We show here that envelope glycoproteins derived from both viruses can pseudotype human immunodeficiency virus type 1 (HIV-1)-derived lentivirus vectors. Both RRV and SFV glycoproteins considerably expand the host range of the lentivirus ...

Pseudotyped lentivirus vectors derived from simian immunodeficiency virus SIVagm with envelope glycoproteins from paramyxovirus.

We describe the development of novel lentivirus vectors based on simian immunodeficiency virus from African green monkey (SIVagm) pseudotyped with Sendai virus (SeV) envelope glycoproteins. SeV fusion (F) and hemagglutinin-neuraminidase (HN) proteins were successfully incorporated into the SIVagm-based vector by truncation of the cytoplasmic tail of the F protein and by addition of the cytoplas...

Highly Efficient Gene Expression in B Lymphocytes Mediating by Lentivirus Vector

Gene transduction and expression efficiencies among several type cell lines were compared by using vesicular stomatitis virus-glycoprotein (VSV-G) pseudotyped human immunodeficiency virus type-1 (HIV-1) based lentivirus vector. Large discrepancies of the efficiencies were shown among them. B lymphocytes showed high susceptibility of the gene transduction and expression, while other cell lines m...

A packaging cell line for lentivirus vectors.

Lentivirus vectors can transduce dividing and nondividing cells. Using three-plasmid transient transfections, high-titer (>10(9) IU/ml) recombinant lentivirus vectors pseudotyped with vesicular stomatitis virus G (VSV-G) protein can be generated (T. Kafri et al., Nat. Genet. 17:314-317, 1997; H. Miyoshi et al., Proc. Natl. Acad. Sci. USA 94:10319-10323, 1997; L. Naldini et al., Science 272:263-...
