Mad Cow Disease or BSE (bovine spongiform encephalopathy) is a progressive neurological disorder of cattle that results from infection by an unusual transmissible agent called a prion. The nature of the transmissible agent is not well understood. Currently, the most accepted theory is that the agent is a modified form of a normal protein known as prion protein. For reasons that are not yet understood, the normal prion protein changes into a pathogenic (harmful) form that then damages the central nervous system of cattle.
Transmissible spongiform encephalopathies (TSEs), or prion diseases, are a family of rare progressive, neurodegenerative illnesses that affect both humans and animals. TSE surveillance is important for public health and food safety because TSEs have the potential of crossing from animals to humans, as seen with the spread of mad cow disease, or bovine spongiform encephalopathy (BSE). A study in The Journal of Molecular Diagnostics describes an advanced assay that offers better sensitivity than currently available tests for detecting a prion disease affecting elk.
Deciphering the mechanism that underlies the development of Alzheimer's disease in certain families but not in others, researchers at the Hebrew University of Jerusalem's Faculty of Medicine have proposed that the malady is actually a collection of diseases that probably should be treated with a variety of different approaches.
Liquid crystals are familiar to most of us as the somewhat humdrum stuff used to make computer displays and TVs. Even for scientists, it has not been easy to find other ways of using them.
Research from Eric Kandel's lab at Columbia University Medical Center has uncovered further evidence of a system in the brain that persistently maintains memories for long periods of time. And paradoxically, it works in the same way as mechanisms that cause mad cow disease, kuru, and other degenerative brain diseases.
Working towards the ultimate goal to develop therapeutics to treat diseases such as Alzheimer's, Parkinson's, ALS, and BSE (Mad Cow Disease), University of Alberta scientists Michael Woodside, Hao Yu, and Derek Dee are investigating the physical principles underlying the formation of misfolded protein aggregates.
Two male academics and one female academic from the University of Zurich have been selected to receive the EU's most prestigious research grant. Each will receive between 2.5 and 2.9 million Euro to support innovative research projects over the next five years.
Grass plants can bind, uptake and transport infectious prions, according to researchers at The University of Texas Health Science Center at Houston (UTHealth).
Researchers from the BIOCAPS Area of 'Biomaterials, tissue engineering and regenerative medicine' have managed to obtain bioceramics from shark teeth, which have already tested applications in the regeneration of bone tissue, particularly in the fields of traumatology and odontology.
Chronic wasting disease (CWD) — an infectious disease caused by prions — affects North American elk and deer, but has not been observed in humans. Using a mouse model that expresses an altered form of the normal human prion protein, researchers at University of California, San Diego School of Medicine have determined why the human proteins aren't corrupted when exposed to the elk prions.
Scientists from the Florida campus of The Scripps Research Institute have for the first time discovered a killing mechanism that could underpin a range of the most intractable neurodegenerative diseases such as Alzheimer's, Parkinson's and ALS.
The new study, published recently in the journal Brain, revealed the mechanism of toxicity of a misfolded form of the protein that underlies prion diseases, such as bovine spongiform encephalopathy (“mad cow disease”) and its human equivalent, Creutzfeldt-Jakob disease.
INRA scientists have shown for the first time that the pathogens responsible for scrapie in small ruminants (prions) have the potential to convert the human prion protein from a healthy state to a pathological state. In mice models reproducing the human species barrier, this prion induces a disease similar to Creutzfeldt-Jakob disease.
Researchers at NYU Langone Medical Center and elsewhere say that a vaccination they have developed to fight a brain-based, wasting syndrome among deer and other animals may hold promise on two additional fronts: Protecting U.S. livestock from contracting the disease, and preventing similar brain infections in humans.
Researchers at UC San Francisco and UC Berkeley have teamed up to create an innovative, integrated center for research on neurodegenerative diseases. Supported by a $3 million grant from the Glenn Foundation for Medical Research, the new center aims to pave the way to developing novel treatments for diseases such as Alzheimer's disease and Parkinson's disease by investigating the many ways that proteins can malfunction within cells.
V3 Healthcare Strategies, a Wisconsin-based Accountable Care Strategies company, announced the North American launch of the revolutionary Hypo-tec Needlestick Injury Prevention Product amidst an environment of infectious catastrophic diseases such as Ebola, Hanta & Hemorrhagic Fevers, while simultaneously protecting against all other infectious diseases such as HIV/AIDS, Hepatitis and more.
The misfolded and infectious prion protein that is a marker for variant Creutzfeldt-Jakob disease - linked to the consumption of infected cattle meat - has been detected in the urine of patients with the disease by researchers at The University of Texas Health Science Center at Houston (UTHealth) Medical School.
The prion diseases were originally discovered by Dr Gajdusek and Dr Gibbs. The first disease discovered was Kuru, which was affecting native tribes in the Papua New Guinea highlands in the 1950s.
New research from David Westaway, PhD, of the University of Alberta and Jiri Safar, MD, Case Western Reserve University School of Medicine has uncovered a quality control mechanism in brain cells that may help keep deadly neurological diseases in check for months or years.

Creuztfeldt-Jakob disease (CJD) is a rare but fatal disease in humans. For the first time, the presence of infectivity in the blood of patients affected by sporadic and the new variant of CJD was established by scientists from the French National Institute for Agricultural Research (INRA) and the French National Veterinary School (ENVT), in collaboration with European partners.
