Mad Cow Disease News and Research

RSS

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.

Creutzfeldt-Jakob disease patients harbor infectious prions in their skin

Creutzfeldt-Jakob disease (CJD)- the human equivalent of mad cow disease- is caused by rogue, misfolded protein aggregates termed prions, which are infectious and cause fatal damages in the patient's brain. CJD patients develop signature microscopic sponge-like holes in their brains.

Protein research could pave way to potential treatments for neurodegenerative diseases

Research carried out at the University of Kent has the potential to influence the future search for treatment of neurodegenerative diseases that are linked to a family of protein molecules known as 'amyloid'.

New antibodies may halt key pathological mechanisms across several neurological diseases

A new kind of antibody targets a feature shared by proteins thought to cause the most damage in Alzheimer's disease, Parkinson's disease, and related conditions, creating potential for a unified treatment approach.

Research suggests how malformed proteins linked to Parkinson’s could spread from the gut to the brain

Recent research on Parkinson's disease has focused on the gut-brain connection, examining patients' gut bacteria, and even how severing the vagus nerve connecting the stomach and brain might protect some people from the debilitating disease.

Study unravels mystery of how nerve cells are damaged in neurodegenerative diseases

A new study has uncovered a molecular mechanism in the prion protein, a protein responsible for neurodegenerative diseases, which may explain why nerve cells degenerate in these disorders.

New research shows how to prevent prions from growing into deadly diseases

Prion diseases are scary, incurable and fatal. They first gained notoriety when cows became infected by prion proteins and, in turn, infected people. Fervor surrounding mad cow disease resulted in the U.S. banning imports of beef from the European Union for 15 years.

Structure of unique amyloid fibrils could lead to discovery of new antibiotics

The highly pathogenic Staphylococcus aureus bacteria is one of the five most common causes of hospital-acquired infections. In the US alone, approximately 500,000 patients at hospitals contract a staph infection. It is the bacteria responsible for MRSA, for which there is no vaccine.

New detection method could lead to noninvasive diagnosis of Creutzfeldt-Jakob disease

The detection of prions in the blood of patients with variant Creutzfeldt-Jakob disease could lead to a noninvasive diagnosis prior to symptoms and a way to identify prion contamination of the donated blood supply, according to researchers at McGovern Medical School at The University of Texas Health Science Center at Houston.

Study finds blood thinning drugs derived from cattle and pigs have equivalent anti-clotting properties

As demand for the widely used blood thinning drug heparin continues to grow, experts worry of possible shortages of the essential medication.

Prion proteins can drive emergence of new traits and adaptive opportunities

Prion proteins, best known as the agents of deadly brain disorders like mad cow disease, can help yeast survive hard times and pass the advantageous traits down to their offspring, according to a new study by researchers at the Stanford University School of Medicine.

Groundbreaking research unravels structure of infectious prions that cause mad cow disease

Groundbreaking research from the University of Alberta has identified the structure of the infectious prion protein, the cause of "mad cow disease" or BSE, chronic wasting disease in deer and elk and Creutzfeldt-Jakob disease in humans, which has long remained a mystery.

Scientists unravel effect of prion proteins on the nerves

Ever since the prion gene was discovered in 1985, its role and biological impact on the neurons has remained a mystery.

Researchers clarify beneficial function of brain protein linked to mad cow disease

Scientists have clarified details in understanding the beneficial function of a type of protein normally associated with prion diseases of the brain, such as bovine spongiform encephalopathy (commonly known as mad cow disease) and its human counterpart, variant Creutzfeldt-Jakob disease.

UTHealth researchers receive $11 million grant to study prion diseases

Led by Claudio Soto, Ph.D., researchers from McGovern Medical School at The University of Texas Health Science Center at Houston have been awarded $11 million from the National Institute of Allergy and Infectious Diseases to study the pathogenesis, transmission and detection of prion diseases - such as chronic wasting disease in deer - that can potentially spread to humans.

Actin filaments may be key to molecular machinery that forms, stores long-term memories

Thank the little "muscles" in your neurons for allowing you to remember where you live, what your friends and family look like and a lot more.

Advanced assay offers better sensitivity for detecting a prion disease affecting elk

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.

Scientists propose that Alzheimer's disease should be treated separately

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.

Novel approach promises easier way to detect protein fibers implicated in neuro-degenerative diseases

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 shows how prion-like proteins critical for maintaining long-term memories

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.
