Working independently, three teams of researchers have
developed a clear picture of the structure and mechanism of the misshapen, threadlike proteins — called prions in their infectious form — that are the hallmarks of
mad cow disease, Alzheimer's, Parkinson's, and 19 other brain - wasting diseases.
As a result, an abnormally high number of the children treated
developed Creutzfeldt - Jakob Disease, also known as «
Mad Cow Disease.»
