摘要: Vesicular stomatitis virus, human immunodeficiency virus type 2, and foamy which were produced by cell lines expressing galactosyl(alpha1-3)galactosyl (alphaGal) sugars, found to be less stable in serum than those from alphaGal-negative cells, indicating that galactosyl(alpha1-3)galactosylation sensitizes these viruses as well mammalian C oncoviruses (Rother et al., J. Exp. Med. 182:1345-1355, 1995; Takeuchi Nature (London) 379:85-88, 1996) complement killing via natural anti-alphaGal antibodies. Thus, mediated antibodies may play a role barrier animal-to-human infection of various enveloped viruses. Virus vectors for vivo gene therapy based on the mentioned above should cells.
