question: What is Creutzfeldt-Jakob Disease (CJD)?
answer: Creutzfeldt-Jakob disease (CJD) is the most prevalent of the human prion diseases, which are fatal and transmissible neurodegenerative diseases caused by the infectious prion protein (PrP(Sc)). The origin of CJD is unknown, although the initiating event is thought to be the stochastic misfolding of endogenous prion protein (PrP(C)) into infectious PrP(Sc).
