The Protein Srebp2 Drives Cholesterol Formation in Prion-Infected Neuronal Cells Which May Promote Prion-Dependent Diseases
The regulating protein Srebp2 drives cholesterol formation, which prions need for their propagation, in prion-infected neuronal cells. view more (2009-11-19)
Cell study explains why younger people 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. view more (2009-10-14)
Prion study reveals first direct information about the protein's molecular structure
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. view more (2009-10-07)
One nano-step closer to weighing a single atom
By studying gold nanoparticles with highly uniform sizes and shapes, scientists now understand how they lose energy, a key step towards producing nanoscale detectors for weighing any single atom. view more (2009-07-28)
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)
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. view more (2009-04-03)
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. view more (2009-03-16)
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)
Self-regulating molecular 'transformers' control intracellular protein delivery
Scientists from the California Institute of Technology (Caltech) have uncovered the Transformer like properties of molecules responsible for carrying and depositing proteins to their correct locations within cells. view more (2009-02-11)
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)
Deadly dose: Rensselaer heparin expert helps uncover source of lethal contamination
The mysterious death of patients around the world following a routine dosage of the common blood thinner, heparin, sent researchers on a frantic search to uncover what could make the standard drug so toxic. view more (2008-04-28)
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 cholesterol in other neurodegenerative diseases. view more (2008-02-12)
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)
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 the Centre for Prions and Protein Folding Diseases... view more...

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)
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)
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)
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)
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)
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)
