Research Abstract

There are MV2 cases in sporadic Creuzfeldt-Jakob disease. We established the method to classify these MV2 cases into cases with V2 prions or M2 prions. In Western blot analysis, T-1 antibody revealed Mi PrPres molecule in cases with V2 prions, while this antibody did not detected in cases with M2 prions. In cases with V2 prions, the infectivity shows the similar pattern with VV2 prions. Therefore, we established the practical classification method of MV2 prions.
