Variant prion protein causes infection but no symptoms

...eases such as Creutzfeldt-Jacob disease in people, mad cow disease in cattle and chronic wasting disease in deer and elk. Now, new research suggests that a variant form of abnormal prion protein--one lacking an "anchor" into the cell membrane--may be unable to signal cells to start the lethal disease pro...

Prions rapidly 'remodel' good protein into bad, Brown study shows

...s proteins that cause fatal brain ailments such as mad cow disease and scrapie in animals and, in rare cases, Creutzfeldt-Jacob disease and kuru in humans. Because similar protein self-replication occurs in neurodegenerative diseases, the findings, published in the latest issue of Nature, may also help ...

Prion find points way to test for human 'mad cow' disease

...ow many people are infected with the human form of mad cow disease, which can take as long as 40 years before manifesting itself. Such a blood test could also help prevent accidental transmission of the malformed proteins that cause variant Creutzfeldt-Jakob disease (vCJD) via blood transfusions and org...
