The fate of the prion protein in the prion/plasminogen complex

Biochemical and Biophysical Research Communications, 2003
The cellular prion protein (PrP(c)) forms complexes with plasminogen. Here, we show that the PrP(c) in this complex is cleaved to yield fragments of PrP(c). The cleavage is accelerated by plasmin but does not appear to be dependent on it.

Aptamers against prion proteins and prions

Cellular and Molecular Life Sciences, 2009
Prion diseases are fatal neurodegenerative and infectious disorders of humans and animals, characterized by structural transition of the host-encoded cellular prion protein (PrP(c)) into the aberrantly folded pathologic isoform PrP(Sc). RNA, DNA or peptide aptamers are classes of molecules which can be selected from complex combinatorial libraries for ...

Structural Studies of Prion Proteins and Prions

2011
Prion diseases are a group of fatal and incurable neurodegenerative ­disorders of mammals. They uniquely manifest as sporadic, genetic, and infectious maladies. The agent responsible for prion diseases is the prion. A prion is defined as a proteinaceous infectious particle, which is solely constituted by an alternately folded form of the prion protein (

Human prion diseases with variant prion protein

Philosophical Transactions of the Royal Society of London. Series B: Biological Sciences, 1994
Abstract Recent molecular genetic studies revealed that the human prion protein (PrP) gene has a large repertoire of polymorphisms and mutations. Each variant PrP seems to correspond to a distinct type of prion diseases. W e report herein that it is useful to classify prion diseases into plaque type or non-plaque type, based on the ...

Prion Protein Functions and Dysfunction in Prion Diseases

Current Medicinal Chemistry, 2009
Prion diseases are zoonotic infectious diseases caused by infectious particles, termed prions. Main component of prions is presumably a misfolded, partially protease-resistant conformer (PrP(Sc)) of a normal cell surface protein, the cellular prion protein (PrP(C)), whose anti-oxidative role is presumed by studies using prion protein (PrP)-knockout ...

Prion Protein Oligomerization

Current Alzheimer Research, 2008
The PrP propensity to adopt different structures is tightly linked to transmissible spongiform encephalopathies (TSE) which include Creutzfeldt-Jakob disease (CJD), Gerstmann-Sträussler-Scjeinker (GSS) and Kuru syndrome. In most cases, TSE is associated with the accumulation in the brain of an abnormally folded protease-resistant protein, PrP Sc or ...

Immunology of Prion Protein and Prions

2017
Many natural prion diseases are acquired peripherally, such as following the oral consumption of contaminated food or pasture. After peripheral exposure many prion isolates initially accumulate to high levels within the host's secondary lymphoid tissues. The replication of prions within these tissues is essential for their efficient spread to the brain

Prions and prion proteins.

FASEB journal : official publication of the Federation of American Societies for Experimental Biology, 1991
Neurodegenerative diseases of animals and humans including scrapie, bovine spongiform encephalopathy, and Creutzfeldt-Jakob disease are caused by unusual infectious pathogens called prions. There is no evidence for a nucleic acid in the prion, but diverse experimental results indicate that a host-derived protein called PrPSc is a component of the ...

Mammalian prion proteins

Current Opinion in Structural Biology, 2000
The past two years have seen the extension of our knowledge on the cellular prion protein structure with new NMR data on both the hamster and human proteins. In addition, the folding dynamics of two cellular prion proteins have been elucidated. There are now several examples of recombinant prion proteins that are able to adopt different conformations ...
