MethodsThe animal model was achieved by feeding a high-cholesterol diet to rabbits for 4 months. Fifty-two New Zealand White rabbits were divided into treatment groups: untreated control, high-cholesterol diet only, antibodies only, focused US only, and focused US and antibodies. Three sessions of focused US were administered to the treatment groups. ResultsIt was shown that with this animal model, the plaques were 30m in diameter. By increasing the number of sessions, the number of plaques decreased (both for focused US only and focused US and antibodies). Without the application of focused US, the average number of plaques dropped from 200/cm(2) (before treatment) to 170/cm(2) (after treatment). The effect of treatment with focused US with antibodies was more drastic. With 3 BBB opening sessions, the average number of plaques was reduced from 200 to 78/cm(2). ConclusionsThis feasibility study had demonstrated that by opening the BBB, it will be possible to deliver exogenous antibodies to the brain, thus eliminating amyloid plaques. More importantly with repeated opening of the BBB (3 times in this study), the reduction in the number of plaques was increased. | URI: | https://hdl.handle.net/20.500.14279/10500 | ISSN: | 02784297 | DOI: | 10.1002/jum.14256 | Rights: | Copyright © 1999 - 2017 John Wiley & Sons, Inc. | Type: | Article | Affiliation : | Cyprus University of Technology | Publication Type: | Peer Reviewed |
