Morphine Withdrawal Modifies Prion Protein Expression in Rat Hippocampus. [PDF]

open access: yesPLoS ONE, 2017
The hippocampus is a vulnerable brain structure susceptible to damage during aging and chronic stress. Repeated exposure to opioids may alter the brain so that it functions normally when the drugs are present, thus, a prolonged withdrawal might lead to ...

Prion protein interconversions† [PDF]

open access: yesPhilosophical Transactions of the Royal Society of London. Series B: Biological Sciences, 2001
The transmissible spongiform encephalopathies (TSEs), or prion diseases, remain mysterious neurodegenerative diseases that involve perturbations in prion protein (PrP) structure. This article summarizes our use ofin vitromodels to describe how PrP is converted to the disease–associated, protease–resistant form.

Prion Neurotoxicity: Insights from Prion Protein Mutants [PDF]

open access: yesCurrent Issues in Molecular Biology, 2010
The chemical nature of prions and the mechanism by which they propagate are now reasonably well understood. In contrast, much less is known about the identity of the toxic prion protein (PrP) species that are responsible for neuronal death, and the cellular pathways that these forms activate.

Prion protein and prion disease at a glance [PDF]

open access: yesJournal of Cell Science, 2021
ABSTRACT Prion diseases are neurodegenerative disorders caused by conformational conversion of the cellular prion protein (PrPC) into scrapie prion protein (PrPSc). As the main component of prion, PrPSc acts as an infectious template that recruits and converts normal cellular PrPC into its pathogenic, misfolded isoform. Intriguingly, the

The cellular prion protein beyond prion diseases

open access: yesSwiss Medical Weekly, 2020
The cellular prion protein (PrPC), a cell surface glycoprotein originally identified for its central role in prion diseases (also called transmissible spongiform encephalopathies), has recently been implicated in the pathogenesis of other neurodegenerative disorders, such as Alzheimer’s and Parkinson’s diseases, by acting as a toxicity-transducing ...

Prion protein and aging [PDF]

open access: yesFrontiers in Cell and Developmental Biology, 2014
The cellular prion protein (PrP(C)) has been widely investigated ever since its conformational isoform, the prion (or PrP(Sc)), was identified as the etiological agent of prion disorders. The high homology shared by the PrP(C)-encoding gene among mammals, its high turnover rate and expression in every tissue strongly suggest that PrP(C) may possess key

Insight into the conserved structural dynamics of the C-terminus of mammal PrPC identifies structural core and possible structural role of pharmacological chaperones

open access: yesPrion, 2023
Misfolding of the prion protein is central to prion disease aetiology. Although understanding the dynamics of the native fold helps to decipher the conformational conversion mechanism, a complete depiction of distal but coupled prion protein sites common

A Sequence-Dependent DNA Condensation Induced by Prion Protein

open access: yesJournal of Nucleic Acids, 2018
Different studies indicated that the prion protein induces hybridization of complementary DNA strands. Cell culture studies showed that the scrapie isoform of prion protein remained bound with the chromosome. In present work, we used an oxazole dye, YOYO,

A quantitative characterization of interaction between prion protein with nucleic acids

open access: yesBiochemistry and Biophysics Reports, 2018
Binding of recombinant prion protein with small highly structured RNAs, prokaryotic and eukaryotic prion protein mRNA pseudoknots, tRNA and polyA has been studied by the change in fluorescence anisotropy of the intrinsic tryptophan groups of the protein.

Potential Therapeutic Use of Stem Cells for Prion Diseases

open access: yesCells, 2023
Prion diseases are neurodegenerative disorders that are progressive, incurable, and deadly. The prion consists of PrPSc, the misfolded pathogenic isoform of the cellular prion protein (PrPC).
