Gene therapy for neurometabolic disorders

摘要

The disclosure pertains to methods for treating neurometabolic disorder including lysosomal storage diseases that affect the central nervous system, e.g., Niemann-Pick A disease. The disclosed methods involve contacting an axonal ending of a neuron with a composition containing high titer AAV carrying a therapeutic transgene so that the AAV vector is axonally transported in a retrograde fashion and transgene product is expressed distally to the administration site.
