New discovery boosts basic understanding of prion infections

Brittleness is often seen as a sign of fragility. But in the case of infectious proteins called prions, brittleness makes for a tougher, more menacing pathogen.

No prion diseases found in German deer

Presently, there is no evidence of prion diseases in free-living German cervids.

Certain soil types serve as natural prion repositories in the wild

Scientists have confirmed that prions, the mysterious proteins thought to cause chronic wasting disease (CWD) in deer, latch on tightly to certain minerals in soil and remain infectious.

Transportation of prion protein across the intestinal mucosa of scrapie-susceptible and scrapie-resistant sheep

While newly published research confirms that under laboratory circumstances prion-protein can be absorbed across the gut, it also shows that this is unlikely to occur in real life.

New evidence questions the simple link between prion proteins and vCJD

While newly published research confirms that under laboratory circumstances prion-protein can be absorbed across the gut, it also shows that this is unlikely to occur in real life.

New way of targeting proteins to exosomes - potential for melanoma, Alzheimer's disease

Researchers at the University of Pennsylvania School of Medicine have discovered how a protein called Pmel17 is sorted by pigment cells in the skin and eye to make a fiber matrix that eventually sequesters melanin, the dark pigment found in skin, hair, and eyes.

New test for detecting small amounts of proteins in the blood

Researchers at the University of Pennsylvania School of Medicine have developed a paradigm-shifting method for detecting small amounts of proteins in the blood.

Genesis bioventures announces worldwide distribution rights for rapid prion-detection technology

Genesis Bioventures, Inc. has announced that the Company has signed exclusive worldwide sales, marketing and distribution agreements with Prion Developmental Laboratories Inc. (PDL) to commercialize the recently patented Rapid Prion-Detection Assay tests developed by PDL.

Prion protein codon 129 genotype prevalence is altered in primary progressive aphasia

Most people with a rare type of dementia called primary progressive aphasia (PPA) have a specific combination of prion gene variants, a new study shows.

Chronic Wasting Disease in deer and humans

Researchers at Binghamton University have a first-ever opportunity to determine if Chronic Wasting Disease (CWD) in deer can be spread to humans who ingest "infected" meat.

Resveratrol effective in lowering amyloid-beta peptides

A study published in the November 11 issue of the Journal of Biological Chemistry shows that resveratrol, a compound found in grapes and red wine, lowers the levels of the amyloid-beta peptides which cause the telltale senile plaques of Alzheimer's disease.

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 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.

4 Aug 2005

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.

9 Jun 2005

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.

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).
