Gene transfer of human acid sphingomyelinase corrects neuropathology and motor deficits in a mouse model of Niemann-Pick type A disease

TL;DR: AAV1 was superior to serotypes 2, 5, 7, and 8 in its relative ability to express hASM, alleviate storage accumulation, and correct behavioral deficits, and support the continued development of AAV based vectors for gene therapy of the CNS manifestations in Niemann-Pick type A disease.
Journal ArticleDOI

Combination brain and systemic injections of AAV provide maximal functional and survival benefits in the Niemann-Pick mouse

TL;DR: Animals treated by combination therapy exhibited high levels of hASM in the viscera and brain, which resulted in near-complete correction of storage throughout the body, resulting in normal weight gain and superior recovery of motor and cognitive functions compared to animals treated by either brain or systemic injection alone.
Journal ArticleDOI

Intracerebroventricular infusion of acid sphingomyelinase corrects CNS manifestations in a mouse model of Niemann–Pick A disease

TL;DR: The effectiveness of intracerebroventricular delivery of recombinant human ASM into ASMKO mice showed that ICV delivery of the enzyme led to widespread distribution of the hydrolase throughout the CNS and a significant reduction in lysosomal accumulation of sphingomyelin was observed throughout the brain and also within the spinal cord and viscera.
