New Insights Into Mad Cow Disease: Diversity Of Creutzfeldt-Jakob Disease Agents Discovered
March 17, 2008 — Researchers have identified four separate biochemical subgroups in a selection of cases of Creutzfeldt-Jakob disease. The study suggests that these subgroups could represent distinct prion strains in ... > full story -
Nano-Sensor For Better Detection Of Mad Cow Disease Agent
March 3, 2008 — In an advance in food safety, researchers are reporting development of a nano-sized sensor that detects record low levels of the deadly prion proteins that cause Mad Cow Disease and other so-called ... > full story -
Prions Link Cholesterol To Neurodegeneration
February 11, 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 -
New Tests Identify Lethal Prion Strains Quickly And Accurately
December 4, 2007 — Scientists have developed two new tests for prions, infectious proteins that cause a number of diseases including "mad cow disease," and a human counterpart, variant Creutzfeldt-Jakob disease. These ... > full story -
Levels Of Prion Protein In Brain May Not Be Reliable Marker For Disease
November 30, 2007 — Rapid diagnostic testing used to check for the presence of prion diseases such as "mad cow disease" might fail to identify some highly infectious samples, researchers have ... > full story -
Prion Fingerprints Detected With Glowing Molecule
November 21, 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 -
Lymph Nodes Can Be Key In Spreading Prion Infectivity
September 26, 2007 — Lymph nodes can be crucial for spreading low doses of infective prion agents -- the pathogens responsible for conditions such as scrapie and Creutzfeldt-Jakob disease -- into the nervous system, ... > full story -
Prions May Activate Retroviruses In Infected Brain Cells
September 7, 2007 — Prion proteins may activate endogenous retroviruses in infected brain cells. Prions – an abbreviation for proteinaceous infectious particles – work as a trigger to a set of diseases of ... > full story -
Small Clumps Of Prion Proteins May Be Primary Cause Of Neurodegenerative Diseases
September 5, 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
August 16, 2007 — Scientists have discovered a new protein that may offer fresh insights into brain function in mad cow ... > full story
