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.

Fatal prion diseases have a hidden signature

Medical researchers in Canada and the United States recently published their joint findings that fatal prion diseases, which include BSE or "mad cow disease," have a hidden signature.

Low-temperature plasmas can kill bacteria for a week after treatment

University of California, Berkeley, scientists have shown that ionized plasmas like those in neon lights and plasma TVs not only can sterilize water, but make it antimicrobial - able to kill bacteria - for as long as a week after treatment.

Researchers match protein to the job it performs in human body

Scientists at Rochester Institute of Technology and Dowling College are engaged in a similar game with higher stakes. Instead of cards, they are matching the protein to the job it performs in the human body. Their research could lead to drugs that target proteins and switch on or off specific functions associated with various diseases.

Researchers announce new method to build important heparin drug

Robert Linhardt is working to forever change the way some of the most widely used drugs in the world are manufactured. Today, in the journal Science, he and his partner in the research, Jian Liu, have announced an important step toward making this a reality. The discovery appears in the October 28, 2011 edition of the journal Science in a paper titled "chemoenzymatic synthesis of homogeneous ultra-low molecular weight heparins."

CWRU to lead Cornea Preservation Time Study

Researchers at Case Western Reserve University School of Medicine will lead a national study determining if corneas transplanted up to two weeks after donor death work as well as corneas transplanted up to one week after donor death. The National Eye Institute has awarded a $12.3 million grant to support the work.

Researchers discover several chemical compounds against human prion diseases

In a new study NYU School of Medicine researchers report that they have found several chemical compounds, including an antidepressant, that have powerful effects against brain-destroying prion infections in mice, opening the door to potential treatments for human prion diseases.

MAVS prion-like proteins are involved in innate immunity: Discovery

A person's ability to battle viruses at the cellular level remarkably resembles the way deadly infectious agents called prions misfold and cluster native proteins to cause disease, UT Southwestern Medical Center researchers report.

PrioNet Canada awards University of Western Ontario $600,000 to study neurodegenerative disorders

The University of Western Ontario is one of nine universities which will share 2.9 million dollars in research grants announced by PrioNet Canada to study Prion diseases and neurodegenerative disorders including Alzheimer's.

Research offers avenue for creating Alzheimer's and HIV therapeutics

A new advance by UCLA biochemists has brought scientists one step closer to developing treatments that could delay the onset of Alzheimer's disease and prevent the sexual transmission of HIV.

Travel, hunting, and venison consumption linked to prion diseases

Researchers from the Centers for Disease Control and Prevention have examined the potential for human exposure to prion diseases, looking at hunting, venison consumption, and travel to areas in which prion diseases have been reported in animals.

CSEW fails to protect public health by refusing to take part in variant Creutzfeldt-Jakob disease study

The creation of a post-mortem tissue archive for a study of the human form of mad cow disease failed because of a "misguided" refusal by coroners to participate.

Protein aggregation plays a significant role in cancer

Protein aggregation, generally associated with Alzheimer's and mad cow disease, turns out to play a significant role in cancer. In a paper published in Nature Chemical Biology, Frederic Rousseau and Joost Schymkowitz of VIB, K.U.Leuven and Vrije Universiteit Brussel describe that certain mutations of p53, an important tumor suppressor, cause the protein to misfold in a way that the proteins start to aggregate.

Aminothiazoles as therapeutic leads for prion diseases

Scientists who examined more than 10,000 chemical compounds during the last year in search of potential new drugs for a group of untreatable brain diseases, are reporting that one substance shows unusual promise.

How Huntington's disease proteins move from cell to cell

One bad apple is all it takes to spoil the barrel. And one misfolded protein may be all that's necessary to corrupt other proteins, forming large aggregations linked to several incurable neurodegenerative diseases such as Huntington's, Parkinson's and Alzheimer's.

Researchers identify normal movement mechanisms of PrPC in brain

Researchers at the University of California, San Diego School of Medicine have identified the motors that move non-infectious prion proteins (PrPC) - found within many mammalian cells - up and down long, neuronal transport pathways.

Blood test for screening mad cow disease to come soon: Study

UK scientists have developed a new blood test that can diagnose cases of variant Creutzfeldt-Jakob Disease (vCJD), a rare, fatal brain disease caused by proteins known as prions. These prions are also responsible for the mad cow disease, or bovine spongiform encephalopathy (BSE). This test could in near future be used to identify contaminated blood and prevent transmission of the disease during blood transfusions, the researchers said.

Damaged alpha-synuclein proteins can spread in a 'prion-like' manner: Study

The study, published in the Journal of Clinical Investigation, reveals that damaged alpha-synuclein proteins can spread in a 'prion-like' manner, an infection model previously described for diseases such as BSE.

Study demonstrates role of alpha-synuclein cell-to-cell transfer in Parkinson's disease pathogenesis

The misfolding of abnormal proteins in brain cells is a key element in Parkinson's disease development. A recent study suggests that the sick proteins slowly move between cells, eventually triggering the destruction of the new host cell. The discovery could potentially lead to new therapeutic strategies for neurodegenerative diseases aimed at blocking the spread of protein misfolding throughout the brain.

Airborne prions can induce mad cow disease: Research

Airborne prions are also infectious and can induce mad cow disease or Creutzfeldt-Jakob disorder. This is the surprising conclusion of researchers at the University of Zurich, the University Hospital Zurich and the University of Tübingen. They recommend precautionary measures for scientific labs, slaughterhouses and animal feed plants.

Plasminogen may serve as new target to treat prion diseases

Scientists at the University of Kentucky have discovered that plasminogen, a protein used by the body to break up blood clots, speeds up the progress of prion diseases such as mad cow disease.
