Sulfatides (Sulfogalactosylceramides)

A sulfatide is a type of sulfolipid that is found primarily in the central nervous system and is a myelin-specific sphingolipid. A deficiency of sulfatide in white and gray matter has been associated with Alzheimer’s disease and other types of dementia. Apoliprotein E plays an important regulating role in the metabolism of sulfatides.1 The production of anti-sulfatide antibodies in the cerebrospinal fluid, resulting in a deficiency of sulfatides, may be a cause of degeneration of the myelin sheath leading to multiple sclerosis.2 Metachromatic leukodystrophy is an inherited disorder characterized by a deficiency of the lysosomal enzyme arylsulfatase A and the subsequent toxic accumulation of sulfatide in neural and visceral tissues.3 An immunomodulatory role for sulfatides has been suggested in the pathogenesis of tuberculosis.
