Antibodies to the glutamate/AMPA receptor subunit 3 (GluR3), are found in a human epilepsy, Rasmussen's encephalitis [RE], and were hypothesized as the major cause for the neuronal loss, chronic inflammatory changes and epileptic seizures characteristic of the disease. To establish the pathogenic potential and mechanism of action of such antibodies, we(More)
Gaucher disease is a glycosphingolipid storage disease caused by defects in the activity of the lysosomal hydrolase, glucocerebrosidase (GlcCerase), resulting in accumulation of glucocerebroside (glucosylceramide, GlcCer) in lysosomes. The acute neuronopathic type of the disease is characterized by severe loss of neurons in the central nervous system,(More)
Gaucher disease is an inherited metabolic disorder caused by defective activity of the lysosomal enzyme, glucocerebrosidase, resulting in accumulation of the lipids, glucosylceramide (GlcCer), and glucosylsphingosine (GlcSph). Little is known about the mechanism leading from lipid accumulation to disease, particularly in the acute and subacute neuronopathic(More)
Sandhoff disease is a lysosomal storage disease in which ganglioside GM2 accumulates because of a defective beta-subunit of beta-hexosaminidase. This disease is characterized by neurological manifestations, although the pathogenic mechanisms leading from GM2 accumulation to neuropathology are largely unknown. We now examine the viability, development and(More)
PURPOSE Elucidating the potential contribution of specific autoantibodies (Ab's) to the etiology and/or pathology of some human epilepsies. METHODS Six epilepsy patients with Rasmussen's encephalitis (RE) and 71 patients with other epilepsies were tested for Ab's to the "B" peptide (amino acids 372-395) of the glutamate/AMPA subtype 3 receptor (GluR3B(More)
