    摘要: The present invention relates to a process of entrapping genetic materials in nanoparticles of inorganic metal salts of size below 100 nm diameter to form non-viral carriers for delivery of genes. The process comprises the steps of dissolving surfactants and a cosurfactant in oil to obtain reverse micelles. An aqueous solution of genetic material is added to the reverse micelles. Thereafter the reverse micelles are divided into two equal parts. To one part, aqueous solution of inorganic metal salts is dissolved to obtain optically clear and transparent reverse micelles. To the second part aqueous solution of precipitating agent is added to obtain optically clear and transparent reverse micelles. The two equally divided parts of reverse micelles are mixed to form inorganic nanopartcles encapsulating added genetic material. Thereafter, the nanoparticles are separated from reverse micelles, the inorganic nanoparticles are dispersed in water and dialyzed to remove free metal salts, surfactant and oil.

    摘要: 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.
