- Alzheimer's prevention role discovered for prions
07-03-2007 · EurekAlert!
A role for prion proteins, the much debated agents of mad cow disease and vCJD, has been identified. It appears that the normal prions produced by the body help to prevent the plaques that build up in the brain to cause Alzheimer’s disease. The possible function for the mysterious proteins was discovered by a team of scientists led by Medical Research Council funded scientist Professor Nigel Hooper of the University of Leeds.

02-12-2007 · EurekAlert!
Using a combination of novel technologies, scientists at the Scripps Research Institute and the Whitehead Institute for Biomedical Research have revealed for the first time a dynamic molecular portrait of individual unfolded yeast prions that form the compound amyloid, a fibrous protein aggregate associated with neurodegenerative diseases such as Alzheimer's disease and variant Creutzfeldt-Jacob disease -- the human version of mad cow disease.

- Scientists ID secret to infectious protein
05-10-2007 · Massachusetts Institute of Technology (MIT)
Scientists at MIT and the Whitehead Institute have discovered small but critical regions within prions, infectious proteins that cause mad cow disease or its human equivalent, Creutzfeldt-Jakob disease, through the study of nontoxic yeast prions.

- Scientists identify prion's infectious secret
05-09-2007 · EurekAlert!
Prions are highly robust and infectious proteins, most notable for their central role in bovine spongiform encephalopathy, commonly called mad cow disease. But very little is known about how prions form aggregates of malformed proteins that ultimately result in disease. This study provides initial insights into how prions recruit and distort healthy neighboring proteins.

- Levels of prion protein in brain may not be reliable marker for disease
11-30-2007 · EurekAlert!
Rapid diagnostic testing used to check for the presence of prion diseases such as "mad cow disease" might fail to identify some highly infectious samples, researchers have found.

- Brown team finds crucial protein role in deadly prion spread
01-23-2007 · EurekAlert!
Brown University biologists have made another major advance toward understanding the deadly work of prions, the culprits behind fatal brain diseases such as mad cow and their human counterparts. In new work published online in PLoS Biology, researchers show that the protein Hsp104 must be present and active for prions to multiply and cause disease.

- Scripps scientists develop new tests that identify lethal prion strains quickly and accurately
12-04-2007 · EurekAlert!
Scientists at the Scripps Research Institute in Jupiter, Florida, have developed two new tests for prions, infectious proteins that cause a number of diseases including "mad cow disease," and a human counterpart, variant Creutzfeldt-Jakob disease. These advances open the door to better understanding and diagnosis of these troubling conditions.

- Abnormal glutamine repeats interfere with key transcription factor, leading to neurodegeneration
11-13-2007 · EurekAlert!
Although repeating sequences of three nucleotides encoding some of the bodies' 20 amino acids are a normal part of protein composition, abnormal expansion of trinucleotide repeats is the known cause of multiple inherited neurodegenerative disorders, including Huntington disease. In research with mice, scientists now have discovered more specific information about how this inherited expansion of a normal repeated DNA sequence alters gene expression.

- Blood Transfusion-transmitted Infections: A Global Perspective
09-30-2006 · ScienceDaily
Thanks to the many blood-safety interventions introduced since 1984, the overall risk for most transfusion-transmitted infections has become exceedingly small. In the September 28 issue of the New England Journal of Medicine, Canadian medical experts put into perspective the continuing risk of transfusion-transmitted infections as well as the possible safety interventions that might reduce that risk even further, particularly those due to emerging agents including variant Creutzfeldt-Jakob disease (vCJD) the human counterpart to mad cow disease.

- Alzheimer's, Parkinson's, type 2 diabetes similar at molecular level
04-30-2007 · EurekAlert!
Alzheimer's disease, Parkinson's disease, type 2 diabetes, the human version of mad cow disease, and other degenerative diseases are more closely related at the molecular level than scientists realized, a team reports this week in an advanced online publication of the journal Nature.
