Membrane-anchored PrPSc is the trigger for prion synaptotoxicity. [PDF]

open access: yesPLoS Pathogens
The mechanism by which prions composed of PrPSc cause the neuropathological aberrations characteristic of prion diseases remains elusive. Previous studies have defined a synaptotoxic signaling pathway in which extracellular PrPSc stimulates NMDA receptor-

The prion 2018 round tables (I): the structure of PrPSc

open access: yesPrion, 2019
Understanding the structure of PrPSc is without doubt a sine qua non to understand not only PrPSc propagation, but also critical features of that process such as the strain phenomenon and transmission barriers.

Propagation of PrPSc in mice reveals impact of aggregate composition on prion disease pathogenesis

open access: yesCommunications Biology, 2023
Infectious prions consist of PrPSc, a misfolded, aggregation-prone isoform of the host’s prion protein. PrPSc assemblies encode distinct biochemical and biological properties.

Transmission characteristics of heterozygous cases of Creutzfeldt-Jakob disease with variable abnormal prion protein allotypes

open access: yesActa Neuropathologica Communications, 2020
In the human prion disease Creutzfeldt-Jakob disease (CJD), different CJD neuropathological subtypes are defined by the presence in normal prion protein (PrPC) of a methionine or valine at residue 129, by the molecular mass of the infectious prion ...

Asymmetric-flow field-flow fractionation of prions reveals a strain-specific continuum of quaternary structures with protease resistance developing at a hydrodynamic radius of 15 nm.

open access: yesPLoS Pathogens, 2021
Prion diseases are transmissible neurodegenerative disorders that affect mammals, including humans. The central molecular event is the conversion of cellular prion glycoprotein, PrPC, into a plethora of assemblies, PrPSc, associated with disease ...

Distribution of peripheral PrP(Sc) in sheep with naturally acquired scrapie. [PDF]

open access: yesPLoS ONE, 2014
Accumulation of prion protein (PrPSc) in the central nervous system is the hallmark of transmissible spongiform encephalopathies. However, in some of these diseases such as scrapie or chronic wasting disease, the PrPSc can also accumulate in other ...

Analysis of prion strains by PrPSc profiling in sporadic Creutzfeldt-Jakob disease. [PDF]

open access: yesPLoS Medicine, 2006
BACKGROUND: Prion diseases are a group of invariably fatal neurodegenerative disorders affecting humans and a wide range of mammals. An essential part of the infectious agent, termed the prion, is composed of an abnormal isoform (PrPSc) of a host-encoded

RETRACTED ARTICLE: Neurotropic influenza A virus infection causes prion protein misfolding into infectious prions in neuroblastoma cells

open access: yesScientific Reports, 2021
Misfolding of the cellular prion protein, PrPC, into the amyloidogenic isoform, PrPSc, which forms infectious protein aggregates, the so-called prions, is a key pathogenic event in prion diseases.

Detecting a psoriatic antigen analogous to infectious prion proteins

open access: yesИнфекция и иммунитет, 2019
Until now, psoriatic antigen as a specific antigen derived from some infectious agent potentially related to origin of psoriasis has not been identified, thereby strongly arguing against infectious theory of psoriasis.

Recombinant PrPSc shares structural features with brain-derived PrPSc: Insights from limited proteolysis. [PDF]

open access: yesPLoS Pathogens, 2018
Very solid evidence suggests that the core of full length PrPSc is a 4-rung β-solenoid, and that individual PrPSc subunits stack to form amyloid fibers. We recently used limited proteolysis to map the β-strands and connecting loops that make up the PrPSc
