| Outline of Final Research Achievements |
Human prion diseases are neurodegenerative disorders caused by abnormally folded prion proteins in central nervous system, which can be detected using the quaking induced conversion assay. Because the assay is extremely sensitive comparing with bioassay, the distribution of the prion in patients diagnosed as sporadic form of Creutzfeldt-Jakob disease, at autopsy was examined. Although it has been regard as infectivity can be restricted within central nervous system in case of sporadic form, we found that the prion activities reach at up to 105-7/g of 50% seeding dose in non-neuronal tissues, suggesting that infectious prions exist in various organs.
