| Outline of Final Research Achievements |
We generated GBA2 and GBA3 knockout medaka by CRISPR/Cas9 system and crossed them with GBA1 knockout medaka. The analysis of the double and triple knockout medaka revealed that neither GBA2 nor GBA3 contributes to the pathophysiology in the central nervous system of GBA1 knockout medaka. However, we revealed the novel roles of GBA1 and GBA2 on the metabolism of cholesterol derivatives. The analysis of α-syn BAC Tg;GBA+/- mice revealed accumulation of phosphorylated α-syn in their brains and dopaminergic neuronal loss in the substantia nigra in an age-dependent manner. The low expression of mitochondrial complex I and accumulation of glucosylsphingosine may be associated with their pathophysiology.
