New findings may yield novel therapies for chronic neurodegenerative diseases

We all have at one time or another experienced the typical signs of an infection: the fever, the listlessness, the lack of appetite. They are orchestrated by the brain in response to circulating cytokines, the signaling molecules of the immune system. But just how cytokines' reach extends beyond the almost impenetrable blood-brain barrier has been the topic of much dispute.

Research may point to more effective therapeutic targets for prion diseases

Scientists from The Scripps Research Institute have determined for the first time that prions, bits of infectious protein devoid of DNA or RNA that can cause fatal neurodegenerative disease, are capable of Darwinian evolution.

Proline repeats make teeth strong and resilient

A simple amino acid that is repeated in the center of proteins found in tooth enamel makes teeth stronger and more resilient, according to new research at the University of Illinois at Chicago.

Researchers follow steps that lead some tumor cells to establish metastases

Up to 25% of cancer patients develop metastases in the brain - often long after successful treatment of the primary tumor. In almost all such cases, the prognosis is poor. The mechanisms responsible for the appearance of brain metastases have long been mysterious.

Cellular prion protein and epileptic seizures: researchers find new role

Cellular prion protein (PrPc) plays an essential role in maintaining neurotransmitter homeostasis in the central nervous system. This discovery has been made possible by the observation that both a deficiency and an excess of the protein have a considerable effect on this homeostasis.

Scientists anticipate new approaches in drug development to combat prion infection

The regulating protein Srebp2 drives cholesterol formation, which prions need for their propagation, in prion-infected neuronal cells. With these findings, published in the current issue of the Journal of Biological Chemistry, scientists of Helmholtz Zentrum München and Technische Universität München anticipate new approaches in drug development to combat prion infection.

University of Leeds scientists' discovery could lead to new treatment route for BSE and CJD

A new treatment route for bovine spongiform encephalopathy (BSE) and its human form Creutzfeldt Jakob disease (CJD) could be a step closer thanks to a discovery by scientists at the University of Leeds.

Amorfix Life Sciences detects prions in blood from non-human primates that were orally-infected with BSE

Amorfix Life Sciences, a company focused on treatments and diagnostics for misfolded protein diseases, announced today it has detected prions in blood from non-human primates that were orally-infected with BSE and developed a primate version of vCJD.

Study reveals large structural differences between natural prions and man-made synthetic analogs

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.

Researchers uncover evolutionary ancestry of prion gene

A University of Toronto-led team has uncovered the evolutionary ancestry of the prion gene, which may reveal new understandings of how the prion protein causes diseases such as bovine spongiform encephalopathy (BSE), also known as "mad cow disease."

Mutations associated with prion diseases are sufficient to cause transmissible neurodegenerative 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.

Nervous system integrity could play a central role in preventing prion diseases

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 W-rzburg, expand our understanding of the development of prion disease and suggest novel targets for therapeutic and diagnostic approaches in its early stages.

Prion found to be a biomarker for pancreatic cancer

Mad cow disease is caused by the accumulation of an abnormal protein, the prion, in the brain of an affected patient. Outside of the brain, very little is known about prions.

Researchers discover how prion protein damages brain cells

Scientists at the National Institutes of Health have gained a major insight into how the rogue protein responsible for mad cow disease and related neurological illnesses destroys healthy brain tissue.

Prevalence of vCJD 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.

Disruption of copper regulation key to prion diseases

An investigation of a rare, inherited form of Creutzfeldt-Jakob disease suggests that disrupted regulation of copper ions in the brain may be a key factor in this and other prion diseases.

New insights may help HIV and cancer patients

Important progress in understanding the function of tetherin, known to have both anti-cancer and anti-viral properties, has been made by researchers at the University of Bristol.

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.
