Novel Approach In Molecular Differentiation Of Prion Strains
August 28, 2008 — Scientists have identified a prion protein characteristic that is unique to some natural but unusual sheep scrapie cases. This finding may provide a novel method by which to study prion diversity and ... > full story -
Investigation Of Prion Folding On Cell Membranes
August 11, 2008 — Abnormally folded proteins cause a number of illnesses such as the Creutzfeldt-Jacob Disease, BSE (bovine spongiform encephalopathy) and Alzheimer’s. It is still unknown why this misfolding ... > full story -
Prions Show Their Good Side
May 9, 2008 — Prions, the infamous agents behind mad cow disease and its human variation, Creutzfeldt-Jakob disease, also have a helpful side. New research shows that normally functioning prions prevent neurons ... > full story -
