Specific downregulation and mistargeting of the lipid raft-associated protein MAL in a glycolipid storage disorder

open access: yesNeurobiology of Disease, 2004
Metachromatic leukodystrophy (MLD) is a lysosomal lipid storage disease caused by arylsulfatase A deficiency. In MLD patients the sphingolipid sulfatide increasingly accumulates leading to progressive demyelination.
