BSE link to new variant CJD is open to question
The link between the bovine spongiform encephalopathy (BSE) prion and new variant Creutzfeldt-Jakob disease is open to question, argues George Venters, Consultant in Public Health Medicine, in this week's BMJ. He applied standard criteria - used to establish links between cause and disease - to... view more (2001-10-09)

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)

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)

New insights into the diversity of Creutzfeldt-Jakob disease agents
Researchers from the United Kingdom and France have identified four separate biochemical subgroups in a selection of cases of Creutzfeldt-Jakob disease.   view more (2008-03-18)

Southampton researchers develop novel method for detecting vCJD prions on surgical instruments
Researchers from the University of Southampton, together with Surrey-based diagnostics company, Microgen Bioproducts Limited, and microscopy specialists, Best Scientific of Swindon, are developing important new methods for detecting prions- the proteins implicated in sporadic and variant... view more (2002-09-26)

Is there more to prion protein than mad cow disease?
Prion protein, a form of protein that triggers BSE, is associated with other brain diseases in cattle, raising the possibility of a significant increase in the range of prion disease.   view more (2008-09-30)

Urgent need for more research into prevalence of CJD
The first estimate of the number of people who are at increased risk of vCJD, but who have not developed symptoms, is published in this week`s BMJ.    Researchers studied specimens from appendicectomies and tonsillectomies carried out between 1995 and 1999. They also examined samples... view more (2002-09-18)

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)

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)

New study raises questions about the number of people in the UK who could be incubating vCJD
A team of UK scientists found that 3 out of 12,674 stored appendix and tonsil samples showed evidence of the prion protein associated with vCJD, but urge caution about the way these results are interpreted. The research is published this week in The Journal of Pathology. The study aimed to help... view more (2004-05-18)

Vaccine prevents prion disease in mice
An oral vaccine can prevent mice from developing a brain disease similar to mad cow disease.   view more (2007-05-04)

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)

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)

The CReSA is working on a new strategy to combat spongiforms
Researchers at the Animal Health Research Centre (CReSA) are developing immunotherapeutical strategies against diseases produced by prion, such as Bovine Spongiform Encephalitis.   view more (2006-11-01)

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)

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)

Large-Scale Tonsillectomy Would Quantify UK CJD Prevalence (pp 1196, 1260)
A study in this week's issue of THE LANCET describes how two different types of analysis used in conjunction on samples of tonsil tissue is the 'gold standard' method for confirming clinical variant CJD, and that a large-scale screening programme of tonsil tissue is the only way of identifying the... view more (2004-09-29)

Prion disease infectivity causes heart damage in mouse study
Laboratory mice infected with the agent of scrapie—a brain-wasting disease of sheep—show high levels of the scrapie agent in their heart several hundred days after being infected in the brain, indicating that heart infection might be a new aspect of this disease.   view more (2006-07-07)

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)

Action needed to prevent spread of vCJD
Urgent action is needed to protect the public from variant Creutzfeldt-Jakob disease (vCJD), a senior member of the Medical Research Council writes in this week's BMJ. Dr Sheila Bird argues that the death of the first probable victim of vCJD from a blood transfusion means that steps must be taken... view more (2004-01-17)

Scientific advance establishes ‘proof of principle’ that prion diseases might be prevented using monoclonal antibody technology
UK scientists have made a major scientific advance by establishing proof of principle that the development of prion disease can be prevented in mice using monoclonal antibodies (mAbs). The work lays the foundation for further research to explore the potential of mAbs to treat specific prion... view more (2003-03-03)

K-State professor's USDA research shows mad cow disease also caused by genetic mutation
