First Atomic-level Look At A Protein That Causes Brain Disease
April 24, 2008 — For the first time, researchers have peered deeply at the atomic level into the protein that causes hereditary cerebral amyloid angiopathy -- a disease thought to cause stroke and dementia. The study ... > full story -
Prions Link Cholesterol To Neurodegeneration
February 12, 2008 — Prion infection of neurons increases the free cholesterol content in cell membranes. A new study suggests that disturbances in membrane cholesterol may be the mechanism by which prions cause ... > full story -
Chemists Characterize Alzheimer's Neurotoxin Structure
December 7, 2007 — Chemists have characterized the molecular structure of the intermediate stage of plaque-forming amyloid fibrils, believed to cause Alzheimer's disease. The finding may lead to new drug targets for ... > full story -
Prion Fingerprints Detected With Glowing Molecule
November 22, 2007 — An effective and sensitive new method for detecting and characterizing prions, the infectious compounds behind diseases like mad cow disease, is now being launched. Mad cow disease (BSE), which has ... > full story -
Small Clumps Of Prion Proteins May Be Primary Cause Of Neurodegenerative Diseases
September 10, 2007 — Scientists have shown for the first time that small clumps of abnormal prion proteins called oligomers cause the widespread death of neurons. In contrast, much larger prion aggregates known as ... > full story -
Newly Discovered Prion Protein May Offer Insight Into Mad Cow Disease
