Metachromatic leukodystrophy (MLD) and globoid cell leukodystrophy (GLD or Krabbe disease) are severe neurodegenerative lysosomal storage diseases (LSD) caused by arylsulfatase A (ARSA) and galactosylceramidase (GALC) deficiency, respectively. Our previous studies established lentiviral gene therapy (GT) as a rapid and effective intervention to provide pervasive supply of therapeutic lysosomal ...
The seeds of Cucurbita maxima contain protein bodies with electrondense globoid crystals. Because of their density globoid crystals are ideal material for energy-dispersive x-ray (EDX) analysis studies of elemental composition. Fixation trials were carried out to test globoid crystal extraction during glutaraldehyde fixation, water washing, and ethanol dehydration. Glutaraldehyde fixation witho...
BACKGROUND This study was conducted to describe the clinical and genetic features of patients with late infantile metachromatic leukodystrophy. METHODS Clinical and genetic manifestations of five Taiwanese patients with late infantile metachromatic leukodystrophy from January 2003 to April 2014 were reviewed. The genetic features of such patients reported in Asian countries during a period of...
Fibroblasts cultured from the skin of a patient with metachromatic leukodystrophy have been found to manifest the biochemical defect of this inborn error of metabolism, a deficiency of arylsulfatase A. Diseased cells had less than five per cent of normal arylsulfatase-A activity, while activities of other lysosomal enzymes-including arylsulfatase B, beta-galactosidase, beta-glucuronidase, and b...
Metachromatic leukodystrophy is a rarely occurring neurodegenerative metabolic disorder with an incidence of 1-9 individuals out of 1,000,000. We present a similar case in an eighteen month old child which was extremely challenging to diagnose. Clinical symptoms suggested motor regression and developmental delay which gave rise to suspicion of a neurodegenerative disorder. An MRI scan of the br...
Globoid cell leukodystrophy (Krabbe disease) is a rare infantile neurodegenerative disorder. Krabbe disease is caused by deficiency in the lysosomal enzyme galactocerebrosidase (GALC) resulting in accumulation, in the micromolar range, of the toxic metabolite galactosylsphingosine (psychosine) in the brain. Here we find that psychosine induces human astrocyte cell death probably via an apoptoti...
Kluyveromyces lactis β-galactosidase (Kl-β-Gal) is one of the most important enzymes in the dairy industry. The poor stability of this enzyme limits its use in the synthesis of galactooligosaccharides (GOS) and other applications requiring high operational temperature. To obtain thermoresistant variants, a rational mutagenesis strategy by introducing disulphide bonds in the interface between th...
The fusion reaction mediated by viral envelope glycoproteins proceeds through an ordered series of conformational changes in the envelope glycoprotein. Fusion inhibitors have been developed that target glycoprotein subunits, arresting the reaction at different points in the process. We report the development of a novel method for detecting viral glycoprotein-mediated fusion that is based on the...
