Abstract

|
The basic concept underlying gene therapy is that human diseases may be treated by the transfer of genetics material into specific cells of a patient in order to correct or supplement defective genes responsible for disease development. There are several systems that can be used to transfer foreign genetic material into the human body. Both viral and non-viral vectors are developed and evaluated for delivering therapeutic genes. Viral vectors are biological systems derived from naturally evolved viruses capable of transferring their genetics materials into host cells. However, the limitations associated with viral vectors, in terms of their safety, particularly immunogenecity, and their limited capacity of transgenic materials, have encouraged researchers to increasingly focus on non-viral vectors as an alternative to viral vectors. Although non-viral vectors are less efficient than viral ones, they have the advantages of safety, simplicity of preparation and high gene encapsulation capability. This article reviews the most recent studies highlighting the advantages and the limitation of gene delivery systems focused on non-viral systems compared to viral systems.
