Although non-viral gene delivery is a very straightforward technology, there are currently no FDA-approved gene medicinal products available. Therefore, improving potency, safety, and efficiency of current plasmid DNA vectors will be a major task for the near future. This article will provide an overview on factors influencing production yield and quality as well as safety issues that emerge fr...

Non-viral gene delivery holds great promise for promoting tissue regeneration, and offers a potentially safer alternative than viral vectors. Great progress has been made to develop biodegradable polymeric vectors for non-viral gene delivery in 2D culture, which generally involves isolating and modifying cells in vitro, followed by subsequent transplantation in vivo. Scaffold-mediated gene deli...

Non-viral gene therapy offers the potential to deliver nucleic acids producing therapeutic proteins to treat genetic diseases without the limitations observed with viral vectors. Before the therapeutic potential of non-viral gene delivery can be realized, several barriers to efficient gene delivery must be overcome. One delivery barrier of interest is the enhancement of endosomal escape to prev...

This report describes novel baculovirus vectors designed to express mammalian beta1,4-galactosyltransferase and alpha2,6-sialyltransferase genes at early times after infection. Sf9 cells infected with these viral vectors, unlike cells infected with a wild-type baculovirus, produced a sialylated viral glycoprotein during the late phase of infection. Thus, the two mammalian glycosyltransferases e...

Epitheliotropic and mucosotropic Papillomaviruses (PVs) constitute the Papillomaviridae family. There are 26 genera comprising levels of inter species genetic similarities by nucleotide sequence analysis of the L1 viral region, the generally most conserved region among papillomaviruses. There is an increasing consensus that the ideal vector for gene therapy should be completely based on chromos...

Human adenoviruses are non-enveloped, icosahedral viruses, approximately 130 nm in diameter. The linear, double-stranded DNA viral genome containing covalently attached terminal protein derived from a unique replication process is almost 36 Kb in length. Although forty nine serotypes of human adenovirus in six serological subgroups have been identified, only serotypes 2 and 5 of subgroup C have...
