Cascade of events leading to prion disease described

Prion diseases are deadly neurodegenerative disorders in humans and animals that are characterized by misfolded forms of prion protein (PrP). Development of effective treatments has been hampered by the lack of good experimental ...

Small loop in human prion protein prevents chronic wasting disease

Chronic wasting disease (CWD)—an infectious disease caused by prions—affects North American elk and deer, but has not been observed in humans. Using a mouse model that expresses an altered form of the normal human prion ...

Researchers show environment can neutralize lethal proteins

Botching a few folds might transform an origami cow into a deer or sheep. When cellular proteins do the same, they can trigger fatal neurodegenerative diseases that turn the brains of these mammals into dysfunctional sponges.

Prion-like proteins drive several diseases of aging

Two leading neurology researchers have proposed a theory that could unify scientists' thinking about several neurodegenerative diseases and suggest therapeutic strategies to combat them.
