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

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

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
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
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
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).
