A person's ability to battle viruses at the cellular level remarkably resembles the way deadly infectious agents called prions misfold and cluster native proteins to cause disease, UT Southwestern Medical Center researchers report. This study marks the first discovery of so-called "good" prion-like proteins in human cells and the first to find such proteins involved in innate immunity: the way the body recognizes and responds to threats from viruses or other external agents, said Dr. Zhijian...

Maryland CWD Containment Area added to list of states impacted by Pennsylvania's parts ban HARRISBURG, Pa., Aug. 8, 2011 /PRNewswire-USNewswire/ -- With thousands of Pennsylvania hunters heading off to hunt big game in other states and Canadian provinces, Pennsylvania Game Commission Executive Director Carl G. Roe reminds hunters that, in an effort to prevent the introduction of Chronic Wasting Disease (CWD) into the Commonwealth, the agency prohibits hunters from importing specific...

It's a chicken and egg question. Where do the infectious protein particles called prions come from? Essentially clumps of misfolded proteins, prions cause neurodegenerative disorders, such as mad cow/Creutzfeld-Jakob disease, in humans and animals. Prions trigger the misfolding and aggregation of their properly folded protein counterparts, but they usually need some kind of "seed" to get started. Biochemists at Emory University School of Medicine have identified a yeast protein called Lsb2...

University of Tennessee molecular biophysics professor reveals a key trigger to a rare but deadly neurodegenerative disease Jeremy Smith, Governor's Chair for Molecular Biophysics at the University of Tennessee, Knoxville, has helped reveal a key trigger of Gerstmann"“Sträussler"“Scheinker (GSS) syndrome, a rare but deadly neurodegenerative disease. The finding could have far-reaching implications for the treatment of other neurodegenerative diseases such as Alzheimer's,...

Unlocking the mechanisms that cause neurodegenerative prion diseases may require a genetic key, suggest new findings reported by University of Illinois at Chicago distinguished professor of biological sciences Susan Liebman. Prions can turn a normal protein into a misfolded form. One prion in mammals promotes progressive neurodegenerative disorders like "mad cow" disease that often prove fatal. But how this process happens remains an open question for scientists. Prions have been found to...

(Ivanhoe Newswire) -- Researchers from the Centers for Disease Control and Prevention (CDC) have examined the potential for human exposure to prion diseases, looking at hunting, venison consumption, and travel to areas in which prion diseases have been reported in animals. Three prion diseases in particular "“ bovine spongiform encephalopathy (BSE or "Mad Cow Disease"), variant Creutzfeldt-Jakob disease (vCJD), and chronic wasting disease (CWD) "“ were specified in the...

Certain lichens can break down the infectious proteins responsible for chronic wasting disease (CWD), a troubling neurological disease fatal to wild deer and elk and spreading throughout the United States and Canada, according to U.S. Geological Survey research published today in the journal PLoS ONE. Like other "prion" diseases, CWD is caused by unusual, infectious proteins called prions. One of the best-known of these diseases is "mad cow" disease, a cattle disease that has infected humans....

Scientists from the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health (NIH), report that they have developed a method"”10,000 times more sensitive than other methods"”to detect variant Creutzfeldt-Jacob disease (vCJD) in blood plasma. vCJD is a type of prion disease in humans that leads to brain damage and death. The NIAID researchers also used the test to rapidly detect scrapie, a prion disease of sheep, in infected hamsters,...

DENVER, April 22, 2011 /PRNewswire/ -- Team Premium Recycled Parts (TEAM PRP) has announced a major expansion of their membership with the creation of a new regional group, PRP Midwest. This new organization serves America's heartland - from Minnesota to Georgia, Texas to Ohio - and was formed by combining the former QRP Midwest, PRP Absolute and PRP Heartland groups. The announcement was made at the Annual TEAM PRP Owner's Meeting, held in conjunction with the United Recyclers Group (URG)...
