Correction of mucopolysaccharidosis type IIIA somatic and central nervous system pathology by lentiviral‐mediated gene transfer

Abstract

The CNS remains the last major barrier to effective therapy for children affected by LSDs. The blood-brain barrier (BBB) limits the uptake of lysosomal enzymes from the peripheral circulation into the CNS, making direct gene delivery to the brain a reasonable, albeit more challenging, therapeutic option. Future work will further assess the relative advantages of directly targeting the brain with somatic gene delivery with sulphamidase modified to increase the efficiency of transport across the BBB.
