Prion Protein Functions and Dysfunction in Prion Diseases
Current Medicinal Chemistry, 2009Prion 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 ...

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
2017Many 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

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 ...

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 ...

From Creutzfeldt-Jakob disease (CJD) to variant CJD through Gerstmann-Sträussler-Scheinker syndrome, kuru and fatal familial insomnia, the journey leading to current understanding of the basic aspects of human prion diseases has been full of unexpected, but often dramatic and always fascinating twists.

Prion Protein Disease and Neuropathology of Prion Disease
Neuroimaging Clinics of North America, 2008Human prion diseases, in common with other neurodegenerative diseases, may be sporadic or inherited and are characterized by the accumulation of cellular proteins accompanied by neuronal death and synaptic loss. Prion diseases are, however, unique in being transmissible.

Physiology of the Prion Protein
Physiological Reviews, 2008Prion diseases are transmissible spongiform encephalopathies (TSEs), attributed to conformational conversion of the cellular prion protein (PrPC) into an abnormal conformer that accumulates in the brain. Understanding the pathogenesis of TSEs requires the identification of functional properties of PrPC.

Quinacrine reactivity with prion proteins and prion-derived peptides
Amino Acids, 2013Quinacrine is a drug that is known to heal neuronal cell culture infected with prions, which are the causative agents of neurodegenerative diseases called transmissible spongiform encephalopathies. However, the drug fails when it is applied in vivo. In this work, we analyzed the reason for this failure. The drug was suggested to "covalently" modify the

Prion proteins: a biological role beyond prion diseases
Acta Neurologica Scandinavica, 2007The biological role of the scrapie isoform of prion protein (PrP(Sc)) as an infectious agent in numerous human and non-human disorders of the central nervous system is well established. In contrast, and despite decades of intensive research, the physiological function of the endogenous cellular form of the prion protein (PrP(C)) remains elusive.
