mucopolysaccharidosis iii/tyrosine

Sanfilippo disease (mucopolysaccharidosis type III, MPS III) is a severe metabolic disorder caused by accumulation of heparan sulfate (HS), one of glycosaminoglycans (GAGs), due to a genetic defect resulting in a deficiency of GAG hydrolysis. This disorder is characterized as the most severe

BACKGROUND Mucopolysaccharidoses (MPSs) are a group of severe metabolic disorders caused by deficiencies in enzymes involved in the degradation of glycosaminoglycans (GAGs)-long chains of sugar carbohydrates in cells that help build bone, cartilage, tendons, corneas, skin, and connective tissue.

Axonal dystrophy has been described as an early pathological feature of neurodegenerative disorders including Alzheimer's disease and amyotrophic lateral sclerosis. Axonal inclusions have also been reported to occur in several neurodegenerative lysosomal storage disorders including

BACKGROUND Mucopolysaccharidoses (MPS) are severe metabolic disorders caused by accumulation of undegraded glycosaminoglycans (GAGs) in lysosomes due to defects in certain lysosomal hydrolases. Substrate reduction therapy (SRT) has been proposed as one of potential treatment procedures of MPS.

Mucopolysaccharidosis type IIIB (Sanfilippo syndrome) is a lysosomal storage disease caused by a genetic defect in the production of alpha-N-acetylglucosaminidase. This results in lysosomal and extracellular accumulation of the undegraded glycosaminoglycan (GAG) substrate, heparan sulphate. Affected

BACKGROUND Neurodegenerative metabolic disorders such as mucopolysaccharidosis IIIB (MPSIIIB or Sanfilippo disease) accumulate undegraded substrates in the brain and are often unresponsive to enzyme replacement treatments due to the impermeability of the blood brain barrier to enzyme. MPSIIIB is
