Prions are a disease-causing form of a normal protein called cellular prion protein (PrPC) that is located primarily on the surface of central nervous system cells but also in other tissues of the body in mammals.
'Prion' is a term first used to describe the mysterious infectious agent responsible for several neurodegenerative diseases found in mammals, including Creutzfeldt-Jakob disease (CJD) in humans. The word itself derives from 'proteinaceous infectious particle'; it refers to the initially heretical hypothesis that the infectious agent causing those diseases consists only of protein, with no nucleic acid genome.
