Increased detection of 14-3-3 protein in cerebrospinal fluid in Sporadic Creutzfeldt-Jakob Disease during the disease course.

摘要

Diagnosis of Creutzfeldt-Jakob Disease (CJD) is based on neurological signs associated with characteristic electroencephalographic activity or detection of 14-3-3 protein in cerebrospinal fluid. However, the time course of 14-3-3 protein release during sporadic CJD is unknown. We report two observations in which the level of the detected 14-3-3 protein increased significantly with time. These preliminary cases suggest that there may be an increased release of 14-3-3 protein during the course of CJD as already proven for iatrogenic CJD.
