Outline of Final Research Achievements |
Anderson-Fabry disease (FD) is a lysosomal storage disorder caused by mutation of the alpha-galactosidase A (GLA) gene. Many FD patients have peripheral neuropathy in the childhoods. This is caused by accumulation of globotoriaosylceramide (Gb3) in dorsal root ganglia (DRG). FD murine model expressed Trpv1 mRNA. The express level was same level as wild-type (WT) mice. Unexpectedly, FD mouse did not show pain symptoms in this experiment. FD mouse showed hyposensitivity to the hot-plate test compare to WT mouse. There were many myelin-like granules in the cytosol of FD DRG neuron. However there was not detected in the axon. It was difficult to observe “patient-like” peripheral neuropathy in this murine model. Our data could not clear the relationship between TRPs and peripheral nerve symptoms.
