Gene Mutation Alone Causes Transmissible Prion Disease
Researchers have shown definitively that mutations associated with prion diseases are sufficient to cause a transmissible neurodegenerative disease. Until now, two theories about the role mutations play in prion diseases have been at odds. Deciphering the origins of prion diseases could help farmers and policy-makers determine how best to control a prion disease outbreak in livestock and to prevent prion transmission to humans.
