Gene therapy for neurodegenerative diseases based on lentiviral vectors.
Gene therapy approaches to treat inherited and acquired disorders offer many unique advantages over conventional therapeutic approaches. For neurodegenerative diseases, gene therapy is particularly attractive due to the restricted bioavailability of conventional therapeutic substances to the affected structures of the brain and progressive nature of these diseases. With the development of lentiviral vector systems, many issues have been addressed and new delivery routes to the nervous system have been identified. Lentiviral vectors can efficiently deliver genes to postmitotic neuronal cell types offering long-term expression, can be generated in high titers, and do not give immunological complications. Various animal studies have demonstrated the effectiveness of these vectors to deliver therapeutic genes into the nervous system, as well as to model human diseases. This chapter will describe the basic features of lentiviral vectors, the progress, and their applications as a therapeutic strategy to treat diseases such as amyotrophic lateral sclerosis, spinal muscular atrophy, Parkinson's disease, and Huntington's disease.
