Leeds Research Finds New Piece Of BSE Puzzle New research funded mainly through the Wellcome Trust with additional support from the Medical Research Council shows that a new treatment route for bovine spongiform encephalopathy (BSE) and its human form Creutzfeldt Jakob disease (CJD) could be a step closer. The research carried out by scientists at the University of Leeds was published today (November 20) in PLoS Pathogens. ...more	21 Nov 2009
Brain Disease "Resistance Gene" Could Offer Insights Into CJD A community in Papua New Guinea that suffered a major epidemic of a CJD-like fatal brain disease called kuru has developed strong genetic resistance to the disease, according to new research by Medical Research Council (MRC) scientists. Kuru is a fatal prion disease, similar to CJD in humans and BSE in animals, and is geographically unique to an area in Papua New Guinea. ...more	21 Nov 2009
The Protein Srebp2 Drives Cholesterol Formation In Prion-Infected Neuronal Cells Which May Promote Prion-Dependent Diseases Prions are causing fatal and infectious diseases of the nervous system, such as the mad cow disease (BSE), scrapie in sheep or Creutzfeldt-Jakob disease in humans. Scientists of Helmholtz Zentrum MÃ¼nchen and Technische UniversitÃ¤t MÃ¼nchen have now succeeded in elucidating another disease mechanism of prion diseases: The prion-infected cell changes its gene expression and produces increased quantities of cholesterol. Prions need this for their propagation. ...more	19 Nov 2009
Why Younger People Are More At Risk Of vCJD Specific cells within the immune system could help explain why younger people are more susceptible to variant CJD, scientists believe. Patients diagnosed with variant CJD are, on average, 28 years old but it has been unclear why older people are not as affected by the disease. ...more	15 Oct 2009
First Direct Information About The Prion's Molecular Structure Reported A collaboration between scientists at Vanderbilt University and the University of California, San Francisco has led to the first direct information about the molecular structure of prions. In addition, the study has revealed surprisingly large structural differences between natural prions and the closest synthetic analogs that scientists have created in the lab. ...more	06 Oct 2009
Gene Mutation Alone Causes Transmissible Prion Disease For the first time, Whitehead Institute researchers have shown definitively that mutations associated with prion diseases are sufficient to cause a transmissible neurodegenerative disease. The discovery is reported in the August 27 edition of the journal Neuron. Until now, two theories about the role mutations play in prion diseases have been at odds. According to one theory, mutations make carriers more susceptible to prions in the environment. ...more	27 Aug 2009
Impaired Transport In Neurons Triggers Prion Disease A new study shows that nervous system integrity and axonal properties may play a key role in prion diseases. The findings, from researchers at the Rudolf Virchow Center and the Institute of Virology of the University of WÃ¼rzburg, expand our understanding of the development of prion disease and suggest novel targets for therapeutic and diagnostic approaches in its early stages. Details are published August 21 in the open-access journal PLoS Pathogens. ...more	25 Aug 2009
Coroners Reluctant To Test For vCJD, UK News According to BBC News, coroners in England and Wales are reluctant to carry out tests for vCJD because it is outside their scope of their job and might undermine their neutrality, despite pleas from scientists and the government that this might be the only effective way to determine how many people might be infected. ...more	19 Aug 2009
EFSA Advises On Welfare Of Dairy Cows EFSA's Panel on Animal Health and Welfare (AHAW) has published five scientific opinions and a scientific report on the overall effects of the most relevant farming systems on the welfare of dairy cows and related diseases. The Panel concluded that long term genetic selection for higher milk yield and the nature of the farming systems used - i.e. housing and equipment, as well as management and handling practices - are major factors affecting the health and welfare of dairy cows. ...more	10 July 2009
Farmed Fish May Pose Risk For Mad Cow Disease University of Louisville neurologist Robert P. Friedland, M.D., questions the safety of eating farmed fish in the June issue of the Journal of Alzheimer's Disease, adding a new worry to concerns about the nation's food supply. Friedland and his co-authors suggest farmed fish could transmit Creutzfeldt Jakob disease--commonly known as mad cow disease--if they are fed byproducts rendered from cows. ...more	18 June 2009
Prevalence Of Variant CJD Agent In Britain Remains Uncertain First results from a large tissue survey in Britain of the agent that causes variant Creutzfeldt-Jakob disease (vCJD) are unable so far to establish that the prevalence is lower than that given by previous estimates, concludes a study published on bmj.com today. ...more	22 May 2009
Research Will Lead To Better Understanding Of Genetic Basis Of Disease The U.S. Department of Agriculture and the National Institutes of Health have announced that an international consortium of researchers has published the genome of domestic cattle, the first livestock mammal to have its genetic blueprint sequenced and analyzed. The landmark research will bolster efforts to produce better beef and dairy products and lead to a better understanding of the human genome. ...more	25 Apr 2009
Redefining What It Means To Be A Prion Whitehead Institute researchers have quintupled the number of identifiable prion proteins in yeast and have further clarified the role prions play in the inheritance of both beneficial and detrimental traits. ...more	04 Apr 2009
Iron Is Involved In Prion Disease-Associated Neuronal Demise Imbalance of iron homeostasis is a common feature of prion disease-affected human, mouse, and hamster brains, according to a new study by Dr. Neena Singh and colleagues at Case Western Reserve University School of Medicine, alongside collaborators from Creighton University. ...more	16 Mar 2009
Prion Discovery Gives Clue To Control Of Mass Gene Expression The discovery in common brewer's yeast of a new, infectious, misfolded protein -- or prion -- by University of Illinois at Chicago molecular biologists raises new questions about the roles played by these curious molecules, often associated with degenerative brain diseases like "mad cow" and its human counterpart, Creutzfeldt-Jakob. ...more	16 Mar 2009
HemoBioTech Announces Dramatic Clearance Of Prions With The ORTH Technology HemoBioTech (OTCBB:HMBT) announced that their orthogonal (ORTH) technology showed to be extremely effective in elimination of prion proteins that cause mad cow disease (BSE) and a similar disease in humans (vCJD/CJD). The ORTH technology removed prion proteins at a rate of 10 -10 from biological fluids used to make specific pharmaceutical products. ...more	12 Mar 2009
Utility Of Circulating DNA As Novel Diagnostics For Human Cancer, Mad Cow Disease And Other Conditions Chronix Biomedical - developing and applying proprietary techniques to detect and analyze circulating nucleic acid sequences for the diagnosis and management of disease - reported that three recent studies published in peer-reviewed journals have further confirmed the potential diagnostic and prognostic utility of fragments of DNA and RNA that circulate in the blood, known as circulating nucleic acids (CNAs). ...more	12 Mar 2009
What Drove The Cow Mad? Lessons From A Tiny Fish - Clues To Understanding Prion Diseases For over twenty years, scientists have known that a normal protein in the brain, PrP, or prion protein, can turn harmful and cause deadly illnesses like Creutzfeldt-Jakob disease (CJD) in humans, and bovine spongiform encephalopathy (BSE) in cattle. What they could not explain is why large amounts of this normal protein are produced by our bodies in the first place. ...more	10 Mar 2009
Oral Quinacrine Does Not Increase Survival In Patients With Prion Disease The drug quinacrine does not increase survival in patients with prion disease. The results of the first major prospective study of a treatment for human prion disease in the UK are published in an Article early Online and in the April edition of The Lancet Neurology. Human prion diseases, such as Creutzfeldt-Jakob disease (CJD), can arise spontaneously, be inherited through a genetic mutation, or develop through infectious transmission. ...more	10 Mar 2009
Discovery Of Antibody Key To Treating Variant CJD 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.
