| abstractText | Twitcher mouse is an authentic murine model of human genetic demyelinating disease, globoid cell leukodystrophy (GLD), or Krabbe disease. Since its discovery at the Jackson Laboratory (Bar Harbor, ME) this model has been used extensively for the morphological, biochemical-enzymatic studies to clarify pathogenesis and also for therapeutic manipulation of genetic demyelinating disease in humans. As a result of these studies, now we know that (1) GLD is caused by a deficiency of lysosomal enzyme galactosylceramidase, and a toxic metabolite, psychosine, accumulates in the tissue, including the nervous system, damaging myelin forming cells and resulting in secondary demyelination; (2) morphological features of demyelination and associated cellular reactions in demyelination in this mutant are similar to those seen in autoimmune or toxic demyelination; and (3) with enzyme supplementation provided by bone marrow transplantation, remyelination occurs to some extent in demyelinated fibers in both central and peripheral nervous systems of twitcher mouse. |
