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 - constituent of the agent that causes BSE in cattle,... 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 take as long as 40 years before manifesting itself. 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 Society for General Microbiology at the Royal... view more...

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)
Scripps Florida scientists devise accelerated method to determine infectious prion strainsScripps Florida scientists devise accelerated method to determine infectious prion strains
Current tests to identify specific strains of infectious prions, which cause a range of transmissible diseases (such as mad cow) in animals and humans, can take anywhere from six months to a year to yield results - a time-lag that may put human populations at risk. view more (2009-05-29)
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 infectious proteins that cause scrapie, bovine... view more... (2002-07-17)
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 Creutzfeld-Jakob disease (CJD) - on surgical instruments.... view more...

Hopes rise for test to spot vCJD
EMBARGOED UNTIL WEDNESDAY 9 OCTOBER 2002 19:00 BST UK CONTACT - Claire Bowles, New Scientist Press Office, London: Tel: +44(0)20 7331 2751 or email claire.bowles@rbi.co.uk A SCREENING test for vCJD, the human form of mad cow disease, could one day ensure no one gets the disease from donated blood. More than 100 people have succumbed to the... view more... (2002-10-09)
Chemistry & Industry - Issue 7 Cover Date 1 April 2002
NEWS Biotech firms flounder (page 4) This year has started badly for biotech companies, with drug trials showing poor clinical performance and analysts downgrading predicted market values. UBS Warburg analyst Karl Keegan comments ‘A lot of the problems that have occurred are a reflection of the naivety of investors and management’... view more... (2002-03-27)
BSE - A Post Industrial Disease?
Ahead of the Commons debate on BSE due to be held next week, an alternative hypothesis about the origin and behaviour of BSE and vCJD is posed in the latest issue of the SCI publication Chemistry & Industry. Dr David Brown of the University of Cambridge suggests that prion diseases are ‘post-industrial phenomena that will spread in... view more... (2001-02-13)
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)
Antibody key to treating variant CJD, scientists find
Scientists at the University of Liverpool have determined the atomic structure of the 'binding' between a brain protein and an antibody that could be key to treating patients with diseases such as variant CJD. view more (2009-03-04)
Study confirms vCJD could be transmitted by blood transfusion
The findings underline the importance of precautions against vCJD transmission, such as the Government decision in 2004 to ban blood donations from anyone who had received a blood transfusion since 1980. view more (2008-08-29)
Researchers discover ancient origins of tuberculosis-causing bacteria
Researchers have long considered tuberculosis, a bacterial respiratory disease that kills 3 million people each year, a relatively recent human affliction. view more (2005-08-19)
Nature press release for 23 November issue
[408479] LIFELINES: DISEASE PRIONS FOUND AND BOUND (pp479–483) The finding that a common blood protein sticks to rogue prions but ignores the normal, harmless variety could one day form the basis of a test for prion diseases such as BSE and CJD. As well as offering insight into how prions cause disease, this selective binding activity might... view more... (2000-11-23)
Prion disease agent causes heart damage in mouse study
These findings raise the possibility that heart infection could be a new aspect of prion diseases, including those that affect humans and livestock, and that these diseases could travel through the blood. view more (2006-07-10)
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 true incidence of vCJD infection. view more (2004-09-29)

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)
