Aberrant production of tenascin-C in globoid cell leukodystrophy alters psychosine-induced microglial functions.
Globoid cell leukodystrophy (GLD), or Krabbe disease, is a rare and often fatal demyelinating disease caused by mutations in the galactocerebrosidase (galc) gene that result in accumulation of galactosylsphingosine (psychosine). We recently reported that the extracellular matrix (ECM) protease, matrix metalloproteinase-3, is elevated in GLD and that it regulates psychosine-induced microglial ac...
متن کاملMMP-3 mediates psychosine-induced globoid cell formation: implications for leukodystrophy pathology.
Globoid cell leukodystrophy (GLD) or Krabbe disease, is a fatal demyelinating disease attributed to mutations in the galactocerebrosidase (GALC) gene. Loss of function mutations in GALC result in accumulation of the glycolipid intermediate, galactosylsphingosine (psychosine). Due to the cytotoxicity of psychosine, it has been hypothesized that accumulated psychosine underlie the pathophysiology...
متن کامل[Globoid cell leukodystrophy].
A 29 year old male with onset of globoid cell leukodystrophy at age 14 is described. This is the first case of enzymatically confirmed globoid cell leukodystrophy with onset of symptoms after the age of ten. This patient is unique because of the late onset and slow progression and extends the clinical spectrum of globoid cell leukodystrophy. Globoid cell leukodystrophy is caused by the deficien...
متن کاملHematopoietic cell transplantation in murine globoid cell leukodystrophy (the twitcher mouse): effects on levels of galactosylceramidase, psychosine, and galactocerebrosides.
Hematopoietic cell transplantation (HCT) prolongs survival in the twitcher mouse, an authentic animal model of human globoid cell leukodystrophy (Krabbe disease; galactosylceramidase deficiency), but the effects of HCT on levels of galactosylceramidase, psychosine, and cerebrosides in the tissues of twitcher mice have not been previously studied. Galactosylceramidase was less than 8% of control...
متن کاملHematopoietic stem-cell transplantation in globoid-cell leukodystrophy.
BACKGROUND Globoid-cell leukodystrophy is caused by a deficiency of galactocerebrosidase, which results in progressive central nervous system deterioration. We investigated whether allogeneic hematopoietic stem-cell transplantation can provide a source of leukocyte galactocerebrosidase and thereby prevent the decline of central nervous system function in patients with the disease. METHODS Fiv...
