"The mis-folded form of the prion protein has been implicated in a
number of diseases 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 are always fatal."<br><br>
