| Outline of Final Research Achievements |
We developed a novel experimental technique that realize widespread gene transduction into neurons throughout the primate brain by the use of viral vectors. Recombinant adeno-associated virus (rAAV) vectors constitute a powerful tool for delivering target genes into the brain. Previous studies reported that AAV9 was able to cross the blood-brain barrier, and that systemic application of a self-complementary AAV9 vector to neonatal mice, rats, and cats yielded efficient gene transduction into neurons. However, gene transduction into neurons of neonatal non-human primates has not yet been performed successfully. In this study, we find that intravascular administration of a capsid-modified AAV9 vector to neonatal macaques resulted in widespread gene transduction into neurons throughout the brain. The present data indicate that this technique is useful in creating genetically manipulated primate models of neuropsychiatric disorders and developing their gene therapeutic approaches.
