Molecular dynamics as an approach to study prion protein misfolding and the effect of pathogenic mutations [PDF]

, 2011
Computer simulation of protein dynamics offers unique high-resolution information that complements experiment. Using experimentally derived structures of the natively folded prion protein (PrP), physically realistic dynamics and conformational changes ...

A Retrospective Cohort Study of a Newly Proposed Criteria for Sporadic Creutzfeldt–Jakob Disease

Diagnostics
Background/Objectives: Sporadic Creutzfeldt–Jakob disease (sCJD) is a fatal neurodegenerative disorder traditionally diagnosed based on the World Health Organization (WHO) criteria in 1998. Recently, Hermann et al.

Aspects of prion protein dynamics in cell culture models. [PDF]

, 2005
The cell biology of Prion formation and transfer is not well understood. In order to further elucidate the dynamics of PrPc and PrPsc in a cellular context, fusions between Green Fluorescent Protein (GFP) and PrP were constructed and infected/uninfected ...

Gene expression profiling en association with prion-related lesions in the medulla oblongata of symptomatic natural scrapie animals. [PDF]

, 2011
The pathogenesis of natural scrapie and other prion diseases remains unclear. Examining transcriptome variations in infected versus control animals may highlight new genes potentially involved in some of the molecular mechanisms of prion-induced ...

Yeast Prions [PDF]

Prion, 2007
Prions (infectious proteins) analogous to the scrapie agent have been identified in Saccharomyces cerevisiae and Podospora anserina based on their special genetic characteristics. Each is a protein acting as a gene, much like nucleic acids have been shown to act as enzymes. The [URE3], [PSI(+)], [PIN(+)] and [Het-s] prions are self-propagating amyloids

Prions And Prion Diseases

African Journal of Clinical and Experimental Microbiology, 2008
A prion is a small infectious particle, which resist inactivation by procedures that modify nucleic acids. Transmissible spongiform encephalopathies (TSEs also known as prion diseases) are a group of progressive conditions that affects the brain and nervous system of humans and animals and are transmitted by prions.

Prions and Prion Diseases [PDF]

Laboratory Medicine, 1999
Prion diseases (transmissible encephalopathies) are progressive neurodegenerative diseases of animals and humans caused by a unique agent, the prion. These diseases have recently been in the news because of the emergence of bovine spongiform encephalopathy (BSE; mad cow disease) and variant Creutzfeldt-Jakob disease (vCJD) in the United Kingdom.

Prions and Prion-Like Pathogens in Neurodegenerative Disorders [PDF]

Pathogens, 2014
Prions are unique elements in biology, being able to transmit biological information from one organism to another in the absence of nucleic acids. They have been identified as self-replicating proteinaceous agents responsible for the onset of rare and fatal neurodegenerative disorders—known as transmissible spongiform encephalopathies, or prion ...

Impact of Chemical Aging on Venison Processing Knife Topography and Recoverable Chronic Wasting Disease Prion Seeding Activity

Pathogens
Infectious prion adsorption on metal, minerals, wood, and plastic is well documented, raising the specter of food safety hazards for meat packing workers, sport hunters, and consumers.

PLGA nanoparticles for oral delivery of prion-specific antigen: a novel approach to chronic wasting disease vaccination

Scientific Reports
Prion diseases, such as chronic wasting disease (CWD), are incurable, fatal neurodegenerative disorders. We have developed a recombinant dimeric deer prion protein (Ddi) vaccine against CWD that has shown promising immune responses when injected ...
