  • A small protein found in the brain cell membrane. The distorted form of this protein is responsible for the mad cow disease and causes new Creutzfeld-Jakob disease in humans.

  • The word prion, coined in 1982 by Stanley B. Prusiner, is a portmanteau derived from the words protein and infection.[3] Prions are responsible for the transmissible spongiform encephalopathies in a variety of mammals, including bovine spongiform encephalopathy (BSE, also known as "mad cow disease") in cattle and Creutzfeldt–Jakob disease (CJD) in humans. All known prion diseases affect the structure of the brain or other neural tissue and all are currently untreatable and universally fatal.
