Redefining what it means to be a prion

... clumped together in brain cells. Brain matter in PrP-infected animals takes on a spongy appearance, lending the condition its formal name, bovine spongiform encephalitis (BSE). Unlike other proteins, the misfolded PrP protein is transmissible. When the misfolded PrP protein is introduced to healthy ...

Scripps scientists develop new tests that identify lethal prion strains quickly and accurately

... (the name stands for proteinaceous infectious particles) are unique infectious pathogens associated with some 15 different diseases, including Bovine spongiform Encephalopathy (mad cow) and its rare human form, variant Creutzfeldt-Jacob disease. Infectious prions, which are thought to consist mainly of an ...

Prions and retroviruses -- an unholy alliance?

... Prions an abbreviation for proteinaceous infectious particles work as a trigger to a set of diseases of the brain and nervous system, the so-called spongiform encephalopathies. These include BSE in cattle, scrapie in sheep and Creutzfeldt Jakobs Disease in humans. Prions are structural variants of a normal ...

There have been hundreds of thousands of bovine spongiform encephalopathy cases, for example, and lots of people exposed to tainted ...

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

... clinical symptoms. The scientists say that they detected prions--the infectious proteins responsible for such brain-destroying disorders as bovine spongiform encephalopathy (BSE) in cattle and vCJD in humans--in the blood of the hamsters in as few as 20 days after the animals had been infected. That ...

Brittle prions are more infectious

... notoriety for their roles in such fatal brain-destroying human diseases as Creutzfeldt-Jakob disease and kuru, and in the animal diseases, bovine spongiform encephalopathy ("mad cow" disease) and scrapie. Yeast and mammalian prions are proteins that transmit their unique characteristics via ...

History of human cannibalism eats away at researchers

... amass in brain tissues to cause fatal neurodegenerative diseases such as mad cow disease. These diseases are cumulatively known as transmissible spongiform encephalopathies (TSEs) and in humans, include CJD (Creutzfeldt-Jakob disease) and kuru. Kuru is confined to a human population in Papua-New Guinea ...

Successful cell engineering may lead to mad cow prevention, say researchers

Strongest proof yet found for prion hypothesis

... Medical Branch at Galveston (UTMB) have produced the strongest proof yet that the mysterious and devastating brain diseases known as "transmissible spongiform encephalopathies" (TSEs) are transmitted by an infectious agent composed only of a malformed protein, and not a virus.
