To understand the pathogenic mechanism underlying Parkinson’s disease, we have generated and characterized Drosophila mutants for all known heritable factors of the recessive form of Parkinson’s disease (autosomal-recessive juvenile Parkinsonism, AR-JP). By examining behavioral and morphological phenotypes of these mutants and by conducting immunohistochemical and biochemical examinations for these mutants, we verified our mutants as relevant models for AR-JP. Through genetic analysis with our transgenic and null mutants for these AR-JP-related genes, we have investigated in vivo interaction between them and found their converging role in protecting mitochondria. We are now studying the detailed molecular mechanism of their interaction and trying to develop effective therapeutic agents for treating Parkinson’s disease in collaboration with medical doctors. |
