| Outline of Final Research Achievements |
Exosome is not only signal small vesicle which is utilized as cell-cell communication in various cells but also in neuronal cells. Even in neurodegenerative diseases, it is considered to be related to the pathological condition. In addition, multisystem atrophy, which is a disease related to Parkinson's disease, is the most doubtful as to elucidation of the propagation / aggregate formation to oligodendrocytes in which the main causative molecule α-synuclein (α-syn) is not originally expressed. Therefore, the propagation mechanism model of α-syn mediated by Exosome for multisystem atrophy was clarified. This was due to the fact that Rpn1 induces the exosome-mediated propagation of α-synuclein and the enhanced expression in glia cells at the transmission destination. Furthermore, functional promoting molecules of Rpn1 were also identified.
