Scientists characterize the most infectious prion protein particles

A new study of prions - apparently malformed proteins that initiate deadly brain diseases such as Creutzfeldt-Jakob disease in humans - has yielded surprising information about how the size of prions relates to their infectivity.

Adlyfe receives award from the development of blood test for animal prion diseases

Adlyfe, Inc., a privately held biotech company headquartered in Rockville, MD, focused on early diagnostics for animal and human brain diseases announced the award today of a $650,000 two year grant from the Department of Environment, Food and Rural Affairs (DEFRA) in the UK for continued development of a sensitive early blood test for animal prion diseases.

New method can detect 'mad cow' proteins in blood

Researchers at the University of Texas Medical Branch at Galveston (UTMB) have found a way to detect the malformed proteins in blood that cause "mad cow disease".

Six possible cases of Creutzfeldt-Jakob disease in Idaho sets alarm bells ringing

According to Idaho officials one case of Creutzfeldt-Jakob disease has been confirmed, and they are investigating five other suspected cases in the state.

New surgical cleaning process reduces risk of vCJD

Scientists say a new cleaning process will reduce the risk of hospital transmission of the human form of mad cow disease.

New clues for the understanding of dementia

Researchers at the Medical Research Council MRC Prion Unit and the Department of Neurodegenerative Disease at the Institute of Neurology, University College London - in collaboration with groups from Copenhagen, Aarhus, Lund and Cambridge - have identified a gene that, when mutated, causes an early onset dementia.

Research opens up new directions for studying prion diseases in humans

The mysterious, highly infectious prions, which cause the severe destruction of the brain that characterizes "mad cow disease" and several human brain degenerative disorders, can be rendered harmless in the laboratory by a slight alternation of the three-dimensional conformation or shape of the prion protein's structure.

Fundamental insights in how amyloid fibers form

Amyloid fibers are best known as the plaque that gunks up neurons in people with neurodegenerative illnesses such as Alzheimer's and Creutzfeldt-Jacob disease--the human analog of mad cow disease.

Novel insights into how prion and other neurodegenerative diseases develop

Abnormal prion proteins are little understood disease agents involved in causing horrific brain-wasting diseases such as Creutzfeldt-Jacob disease in people, mad cow disease in cattle and chronic wasting disease in deer and elk.

Genesis Bioventures signs agreement for control of Mad Cow diagnostic company

Further to a Letter of Intent previously reported, Genesis Bioventures today announced that it has entered into a binding agreement with Efoora Inc. and Prion Developmental Laboratories, Inc. to buy all of Efoora's majority interest shares owned or pledged in PDL thereby gaining controlling interest of PDL. A Form 8-K has been filed with the SEC in this regard. Prior to the Agreement, GBI had one-third equity interest in PDL.

Scientists watch agents of brain-wasting diseases invade and move within brain cells

Scientists for the first time have watched agents of brain-wasting diseases, called transmissible spongiform encephalopathies (TSE), as they invade a nerve cell and then travel along wire-like circuits to points of contact with other cells.

Premature use of stem cell therapy could put patients at risk

The premature use of stem cell therapy could put many patients at risk of viral or prion diseases unless appropriate safety systems are in place, warn experts in this week’s BMJ.

Faulty folding of protein in the environment may cause disease

Serious diseases like Alzheimer's and type-2 diabetes have been shown to be related to unhealthy protein chains that occur when proteins fold incorrectly. In an article in the scientific journal Proceedings of the National Academy of Science, PNAS, a research team directed from Uppsala University shows that similar protein chains in our environment may hasten the process.

Study sheds light on why normal prion proteins may experience age-related mutations in inherited diseases

A new study sheds light on why normal prion proteins may experience age-related mutations in inherited diseases. Researchers at the Case Western Reserve University School of Medicine studied a previously discovered mutation in the prion protein in members of an extended family in Indiana who inherited the prion disease Gerstmann-Straussler-Sheinker (GSS).

Strongest evidence yet that infectious misformed proteins cause mad cow disease

Researchers at the University of Texas Medical Branch at Galveston (UTMB) have produced the strongest proof yet that the mysterious and devastating brain diseases known as "transmissible spongiform encephalopathies" (TSEs) are transmitted by an infectious agent composed only of a malformed protein, and not a virus.

Researchers and drug giant team up to find cure for CJD

The Medical Research Council's Prion Unit, based at University College London, a leading British research group, is joining forces with drugs giant GlaxoSmithKline (GSK) to develop a cure for the disease Creutzfeldt-Jakob Disease (CJD).

Fibril shape is the basis of prion strains and cross-species prion infection

New research on prions, the infectious proteins behind "mad cow" disease and Creutzfeld-Jakob disease in humans, suggests that the ability of prions in one species to infect other species depends on the shape of the toxic threadlike fibers produced by the prion. Two studies on the topic appear in the 8 April issue of the journal Cell.

Research into how prions act in the brain could hold the key to defeating diseases

Scientists at the University of Southampton are continuing their pioneering research into diseases such as Creutzfeld-Jakob Disease (CJD) and related conditions caused by tiny particles known as prions, thanks to a £300,000 grant from the Medical Research Council.

Diagnosis of prions in patients should utilize novel strategy, conformation-dependent immunoassay

A technique for detecting prions in tissue, developed in recent years by UCSF scientists, is significantly more sensitive than the diagnostic procedures currently used to detect the lethal particles in samples of brain tissue from patients, according to a study performed by a UCSF team.

Prions, previously thought to accumulate mainly in the brain can also infect other organs

Prions, infectious proteins associated with bovine spongiform encephalopathy (BSE) or Mad Cow Disease, were previously thought to accumulate mainly in the brain, but Yale and University of Zurich researchers report in Science that other organs can also become infected.
