  • Patent number: 6436708
    Abstract: A gene delivery system which. is both safe and results in long-term expression throughout the brain has been developed. A lipid-entrapped, polycation-condensed DNA (LPD) system has been developed for brain gene delivery, using an adeno-associated vial. (“AAV”) vector in which the transcription unit is flanked by the 145 bp inverted terminal repeats (ITR) of the adeno-associated virus. This AAV plasmid is more effective than a non-ITR containing plasmid in vivo. The results show that the LPD-AAV plasmid complexes efficiently transduce neurons and that gene expression can persist for over 10 months in the brain. Furthermore, the intraventricular delivery method with systemic hyperosmolality results in global gene delivery. The examples show that expression of the human aspartoacyclase (“ASPA”) gene in children with this metabolic disorder can be obtained over a period of many months to a year, with functional activity.
