| Outline of Final Research Achievements |
Sporadic Creutzfeldt-Jakob disease (sCJD), a majority of human prion diseases, is classified in different subtypes which contribute to the occurrence of distinct clinical-pathological phenotypes. In this study, we sought to determine whether a modification of real-time quaking-induced conversion (RT-QUIC) assay, a sensitive diagnostic test for prion diseases, allows for distinguish between subtypes of sCJD. We constructed a several different types of recombinant prion protein (recPrP) mutant as a substrate for RT-QUIC reaction. We compared the prion detective sensitivities of RT-QUIC reaction with mutant recPrPs. RT-QUICs were performed with brain homogenates from several types of prion disease patients or infected mice. As a result, there were slightly differences in RT-QUIC signals between specimens by using mutant recPrP as substrate.
