Protein involved in mad cow disease
This study, published in Brain Research, is an addition to the work of the Department of Pathological Histology and Anatomy at the University of Navarra regarding the manner in which prions enter the digestive tube of bovine animals, from which organ they enter the central nervous system, causing... view more (2005-10-19)
Prion Research Center to open today - Hebrew University-hadassah Medical School Researchers Working To Prevent Mad Cow Disease
Prion Research Center to open today Jerusalem, July 31, 2002 - Scientists around the world are striving to learn as much as possible about the phenomenon that causes mad cow disease so that they will be prepared if and when an epidemic breaks out, according to Dr. Albert Taraboulos of the Institute... view more (2002-07-31)
Prions link cholesterol to neurodegeneration
Prion infection of neurons increases the free cholesterol content in cell membranes. A new study published in the online open access journal BMC Biology suggests that disturbances in membrane cholesterol may be the mechanism by which prions cause neurodegeneration and could point to a role for... view more (2008-02-12)
Should dentists worry about vCJD transmission?
Existing guidelines on treating patients with diseases such as Creutzfelt-Jakob disease (CJD) do not cover dental health in any detail. Writing in the April Journal of the Royal Society of Medicine, Professor Stephen Porter of the Eastman Dental Institute at the University of London suggests... view more (2002-04-02)
Using plastics to track down prions
BSE still remains a highly emotive subject. Consumers of beef products are not the only ones to have lingering doubts: Scientific experts point out that there may still be a risk of contamination from the cinders and ashes left over when infected animal carcasses are incinerated. The reason for... view more (2002-06-07)
Soil-bound prions that cause CWD remain infectious
Scientists have confirmed that prions, the mysterious proteins thought to cause chronic wasting disease (CWD) in deer, latch on tightly to certain minerals in soil and remain infectious. view more (2006-04-14)
Brittle prions are more infectious
Brittleness is often seen as a sign of fragility. But in the case of infectious proteins called prions, brittleness makes for a tougher, more menacing pathogen. view more (2006-06-29)
Mad cow proteins successfully detected in blood
Researchers at the University of Texas Medical Branch at Galveston (UTMB) have found a way to detect in blood the malformed proteins that cause "mad cow disease," the first time such "prions" have been detected biochemically in blood. view more (2005-08-29)
Deadly infectious entity of prions discovered
The mysterious, highly infectious prions, which cause the severe destruction of the brain that characterizes "mad cow disease" and several human brain degenerative disorders, can be rendered harmless in the laboratory by a slight alternation of the three-dimensional conformation or shape... view more (2005-06-10)
Scientists identify prion's infectious secret
Researchers have known for decades that certain neurodegenerative diseases, such as mad cow disease or its human equivalent, Cruetzfeldt-Jakob disease, result from a kind of infectious protein called a prion. view more (2007-05-10)
New prion protein discovered by Canadian scientists may offer insight into mad cow disease
Scientists have discovered a new protein that may offer fresh insights into brain function in mad cow disease. "Our team has defined a second prion protein called 'Shadoo', that exists in addition to the well-known prion protein called 'PrP' " said Professor David Westaway, director of... view more (2007-08-17)
Scripps scientists develop new tests that identify lethal prion strains quickly and accurately
One of the new in vitro tests, called the Standard Scrapie Cell Assay, measures prion infectivity levels in a highly accurate and extremely rapid way, producing results in less than two weeks. view more (2007-12-05)
Cell cultures can sort out Creutzfeldt-Jacob Disease (CJD) and scrapie infectious agents
Research in Japan and at Yale University School of Medicine shows that infection with a weak strain of Creutzfeldt-Jacob Disease (CJD) prevents infection by more virulent strains and that the protection requires persistent replication by the infectious agent, but not misfolded prions. view more (2005-10-21)
New data on "mad cow" disease
A research team at the University of Navarre has detected the presence of the prion protein in the digestive tract of three animal species: the autochthonous Pyrennean cow, in a primate and in rats. This study is the first to describe the exact location of the "healthy" form of the prion... view more (2004-11-16)
Studies validating performance of Pall prion reduction technology presented at AABB
Prion diseases, such as variant Creutzfeldt-Jakob Disease (vCJD), the human form of Bovine Spongiform Encephalopathy or "mad cow" disease, are of growing concern to blood services worldwide because of the potential for transmission through transfusion from asymptomatic donors. view more (2005-10-18)
NIAID scientists characterize the most infectious prion protein particles
A new study of prions-apparently malformed proteins that initiate deadly brain diseases such as Creutzfeldt-Jakob disease in humans-has yielded surprising information about how the size of prions relates to their infectivity. view more (2005-09-08)
Scientists find the pathological prion protein in skeletal muscles of hamster with scrapie
In the May 2003 issue of EMBO reports, researchers from the German Robert Koch Institute in Berlin report finding the pathological prion protein PrPSc in a wide range of skeletal muscles after feeding hamsters with prion-infected food. PrPSc is believed to be an essential - if not the sole -... view more (2003-04-10)
Prion find points way to test for human 'mad cow' disease
In the July 7, 2006, issue of the journal Science, researchers at the University of Texas Medical Branch at Galveston (UTMB) describe experiments that may soon lead to a test that will enable medical science to estimate how many people are infected with the human form of mad cow disease, which can... view more (2006-07-07)
Blocking nerve cells delays onset of prion disease
A chemical that specifically blocking parts of the nervous system can delay the onset of scrapie and could lead to new drugs to prevent vCJD and BSE, medical experts heard today (Thursday 10 January 2002) during a joint meeting of the European Societies of Clinical and Veterinary Virology and the... view more (2001-12-21)
Scripps research study reveals structural dynamics of single prion molecules
New techniques paint clearer picture of amyloid formation associated with protein-based inheritance and neurodegenerative diseases such as mad cow, Alzheimer's. view more (2007-02-13)
Therapy For Mice With Prion Disease Could Offer Benefit To Human Beings With CJD
Authors of a fast-track research letter in this week's issue of THE LANCET describe a therapeutic treatment which increased the survival time for mice with prion disease. These results could represent a new approach to treating CJD in human beings. The lack of an immune response to prions-the... view more (2002-07-17)
Southampton researchers develop novel method for detecting vCJD prions on surgical instruments
