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.

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.

Study looks at Fatal Familiar Insomnia

Fatal Familiar Insomnia (FFI) is one of the diseases considered as rare - there are less than 100 cases described throughout the world.

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.

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.

Protein-misfolding accelerates yeast evolution

Under stress, yeast cells can unleash a remarkable mechanism based on protein-misfolding that gives them new characteristics without requiring genetic mutations.

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).

Prion switching in response to environmental stress

If you have had a hard day at work, you may change your eating habits, perhaps favoring comfort food, but you don't suddenly develop the ability to eat the plate and cutlery.

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.

Tracking down the cause of Mad Cow disease - first synthetic prion protein with an anchor

The cause of diseases such as BSE in cattle and Creutzfeld-Jakob disease in humans is a prion protein. This protein attaches to cell membranes by way of an anchor made of sugar and lipid components (a glycosylphosphatidylinositol, GPI) anchor. The anchoring of the prions seems to have a strong influence on the transformation of the normal form of the protein into its pathogenic form, which causes scrapie and mad cow disease.

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.

FDA issues regulation on animal feeds with added safeguards against BSE

The U.S. Food and Drug Administration today issued a final regulation barring certain cattle materials from all animal feed, including pet food. The final rule further protects animals and consumers against bovine spongiform encephalopathy (BSE, also known as "mad cow disease").

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.

Special filter quickly and effectively removes deadly vCJD protein from blood

Amid concern that recipients of certain blood transfusions may risk infection with a deadly protein responsible for the human form of mad cow disease, researchers in Canada now report development of a special filter that quickly and effectively removes the protein from blood.
