Therapeutic nucleic acids demand specificity and accuracy in design as well as delivery strategies used in replacement or silencing of the target gene. Gene therapy is believed to be the therapy in which the root cause of the diseases can be treated at the molecular level. Generally gene therapy helps in the identification of the origin of the disorder instead of using drugs to diminish or control the symptoms. The application of nucleic acids to treat and control diseases is known as “gene therapy.” Gene therapy consists on the substitution or addition of a functional gene into the nucleus of a living cell, in order to treat a disease or repair a dysfunction, caused by this gene failure. This therapy is used to correct defective genes, which are responsible for genetic diseases. Thus, gene therapy can be used to prevent, treat or regulate hereditary or acquired disorders, by the production of therapeutic proteins. The gene therapy is mediated by the use of viral and non-viral vectors to transport foreign genes into somatic cells to restorative defective genes. This review focuses on viral vectors in detail.
