Gene therapy is a promising method to treat genetic and acquired diseases by utilization of the therapeutic delivery of nucleic acid into host cells. The key to success of gene therapy is to create safe and efficient gene delivery systems. Gene delivery systems are categorized as viral gene delivery systems and non-viral gene delivery systems. Among them, viral delivery systems are the most commonly used due to high delivery efficiency. In viral gene delivery systems, viruses are unable to replicate through redesigning, but can deliver the genes to the cells to provide expression. Viral systems have advantages such as high efficiency, low toxicity, cell type specificity, constant expression, dominating the clinical trials in gene therapy. On the current gene therapy market, the major delivery system of approved products are viral vectors.
