An inherited deficiency of β-galactosylceramidase (GALC) causes the lysosomal storage disease globoid cell leukodystrophy (GLD). The disease is characterized by the accumulation of the cytotoxic metabolite psychosine (galactosylsphingosine), causing rapid degeneration of myelinating cells. Most patients suffer from the infantile form of GLD with onset of(More)
Metachromatic leukodystrophy (MLD) is a lysosomal storage disease caused by a functional deficiency of arylsulfatase A (ASA). Previous studies in ASA-knockout mice suggested enzyme replacement therapy (ERT) to be a promising treatment option. The mild phenotype of ASA-knockout mice did, however, not allow to examine therapeutic responses of the severe(More)
Alzheimer's disease (AD), the most common form of dementia in the elderly, is characterized by two neuropathological hallmarks: senile plaques, which are composed of Aβ peptides, and neurofibrillary tangles, which are composed of hyperphosphorylated TAU protein. Diabetic patients with dysregulated insulin signalling are at increased risk of developing AD.(More)
Arylsulfatase A (ASA) catalyzes the desulfation of sulfatide, a major lipid component of myelin. Inherited functional deficiencies of ASA cause the lysosomal storage disease (LSD) metachromatic leukodystrophy (MLD), which is characterized by intralysosomal accumulation of sulfatide, progressive neurological symptoms and early death. Enzyme replacement(More)
Expansion of CAG repeats, which code for the disease-causing polyglutamine protein, is a common feature in polyglutamine diseases. RNA-mediated mechanisms that contribute to neuropathology in polyglutamine diseases are important. RNA-toxicity describes a phenomenon by which the mutant CAG repeat RNA recruits RNA-binding proteins, thereby leading to aberrant(More)
