| Research Abstract |
Recent report showed glucocerebrosidase (GBA) mutation is a risk of PD, however, precise function between GBA mutation and neuronal degeneration. In this study, we explored the function of GBA mutation in its pathological process. GBA mutation fibroblasts showed apoptotic cell death after addition of mitochondrial toxin or starvation. Moreover, lysosomal enzyme, cathepsin B (CTSB) activity was significantly reduced. But we could not clearly show thatlpha-synuclein is the substrate of CTSB.
