This therapeutic idea focuses on optimizing AAV (Adeno-Associated Virus) serotypes and delivery strategies for enhanced central nervous system (CNS) targeting in neurodegenerative disease gene therapy. While AAV vectors are widely used for CNS gene delivery, current serotypes face limitations in transduction efficiency, blood-brain barrier (BBB) penetration, and neuronal subtype specificity. This approach combines novel serotype engineering, route-of-administration optimization, and targeted capsid modification to achieve superior CNS delivery for therapeutic genes targeting AD, PD, ALS, and FTD.
