alpha2-Macroglobulin covalently linked to poly(L)-lysine can be used as a
vehicle for receptor-mediated gene transfer. This modified alpha2-
macroglobulin maintains its ability to bind to the alpha2-macroglobulin
receptor, and was shown to introduce a luciferase reporter gene plasmid
into HepG2 human hepatoma cells in vitro. The alpha2-macroglobulin receptor
is a very large and multifunctional cell surface receptor, whose rapid and
efficient internalization rate makes it attractive for gene therapy, e.g.
for hepatic gene targeting via injection into the portal vein.
