Lentiviral vectors with measles virus glycoproteins - dream team for gene transfer?
Lentiviral vectors are potent gene transfer vehicles frequently applied in research and lately also in clinical applications. Recent improvements have come from combining lentiviral vectors with engineered envelope proteins, which now allow targeting of cell entry to any cell population of interest, as well as the transduction of quiescent cells of the haematopoietic system. We propose that measles virus envelope glycoproteins are especially well suited for this purpose because they can mediate pH-independent cell entry at the cell surface membrane and can induce cytoskeleton rearrangements that facilitate the transport of lentiviral core particles to the cell nucleus. Lentiviral vectors pseudotyped with measles virus glycoproteins are expected to improve the safety and efficacy of gene transfer to human cells.
