Outline of Final Research Achievements |
The purpose of this study is to clarify the same infectivity between thalamic form of Creutzfeldt-Jakob disease and fatal familial insomnia. For this purpose, we did the transmission experiments with humanized prion protein knock-in mouse. Thalamic form prions showed a unique infectivity, and this infectivity was quite different from the MM1, MV2, VV2, or MM2C prions. The result of Ki-178N mice transmission experiment, which is now on-going study, will lead to the conclusion of this study. In addition to the transmission experiments, we were looking for the cases with MM1 and MM2T prions. We found 3 cases with MM1+2T showing neuronal loss of inferior olivary nucleus. We also have a planning to transmit these MM1+2T cases using humanized knock-in mouse.
