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.

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.

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.

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.

Imbalance of iron homeostasis 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.

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.

Scientists create infectious prion disease in mouse model

A worldwide group of scientists has created an infectious prion disease in a mouse model, in a step that may help unravel the mystery of this progressive disease that affects the nervous system in humans and animals.

Discovery of novel prion infectivity in white and brown fat tissues of mice

Prion diseases, also known as transmissible spongiform encephalopathies, are infectious progressive fatal neurodegenerative diseases which affect humans as well as wild and domestic animals.

Mad Cow disease strain found to be more virulent than classical strain

An atypical prion strain of mad cow disease, also called bovine spongiform encephalopathy or BS, is more virulent than the classical strain, according to a researcher who spoke Nov. 14 at Kansas State University.

Mouse model of prion disease mimics diverse symptoms of human disorder

A comprehensive mouse model of inherited prion disease exhibits cognitive, motor, and neurophysiological deficits that bear a striking resemblance to the symptoms experienced by patients with the human version of "mad cow disease," Creutzfeldt-Jakob disease (CJD).

New molecules with many branches will help unleash potential of nanotechnology

Materials science and the pharmaceutical industry could soon be revolutionized by emerging nanotechnologies based on designer molecules with long complex tree-and branch structures. Such molecules offer almost limitless scope for design of bespoke compounds for specific applications in disease therapy, for novel materials such as resins, as well as electronic displays, and energy storage. Almost every field involving design and synthesis of chemical compounds will be transformed by the arrival of technologies allowing nanoscale design of these branched molecules, known as hyperbranched polymers.

Worries over test for mad cow disease

A new test to screen blood for the incurable human form of mad cow disease could be available within 18 months, but it has raised concerns.

Magnetic resonance studies find clear differences between the structures of infectious and non-infectious prions

Infectious proteins known as prions have been identified as the cause of "mad cow" disease (BSE). The culprits are "incorrectly folded" proteins that can "infect" healthy proteins. The molecular bases for such prion diseases are not yet fully understood.

An atomic view of protein behind hereditary cerebral amyloid angiopathy

For the first time, researchers have peered deeply at the atomic level into the protein that causes hereditary cerebral amyloid angiopathy (CAA) -- a disease thought to cause stroke and dementia.

Prion diseases could be transmitted in sheep via milk

Scrapie can be transmitted to lambs through milk, according to new research published in the online open access journal BMC Veterinary Research.

New insights into the diversity of Creutzfeldt-Jakob disease agents

Researchers from the United Kingdom and France have identified four separate biochemical subgroups in a selection of cases of Creutzfeldt-Jakob disease.

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.

Scientists characterize Alzheimer's neurotoxin structure - potential new treatment approaches

Amyloid plaques, the hallmark of Alzheimer's disease, are clumps of fiber-like misfolded proteins which many experts think cause this devastating neurodegenerative disease.
