Prion peptide-mediated calcium level alteration governs neuronal cell damage through AMPK-autophagy flux

open access: yesCell Communication and Signaling, 2020
Background The distinctive molecular structure of the prion protein, PrPsc, is established only in mammals with infectious prion diseases. Prion protein characterizes either the transmissible pathogen itself or a primary constituent of the disease.

The LBFGS Quasi-Newtonian Method for Molecular Modeling Prion AGAAAAGA Amyloid Fibrils [PDF]

open access: yes, 2012
Experimental X-ray crystallography, NMR (Nuclear Magnetic Resonance) spectroscopy, dual polarization interferometry, etc are indeed very powerful tools to determine the 3-Dimensional structure of a protein (including the membrane protein); theoretical ...

Parallel In-register Intermolecular β-Sheet Architectures for Prion-seeded Prion Protein (PrP) Amyloids*

open access: yesJournal of Biological Chemistry, 2014
Background: The structures of infectious mammalian prions remain unclear. Results: Based in part on NMR data, we developed models with single PrP molecules spanning the entire cross-section of prion fibrils.

To develop with or without the prion protein [PDF]

open access: yesFrontiers in Cell and Developmental Biology, 2014
The deletion of the cellular form of the prion protein (PrP(C)) in mouse, goat, and cattle has no drastic phenotypic consequence. This stands in apparent contradiction with PrP(C) quasi-ubiquitous expression and conserved primary and tertiary structures in mammals, and its pivotal role in neurodegenerative diseases such as prion and Alzheimer's ...

Anti‐Inflammatory Mechanisms of Selenium Nanosheets in Ulcerative Colitis: Protein Corona, GP130 Interaction, and Transcriptomic Profile

open access: yesAdvanced Science, EarlyView.
SeNSs provide a biocompatible, anti‐inflammatory UC therapy. SeNSs form protein coronas enriched with AKT/PI3K/NF‐κB pathway proteins, suppress GP130 via hydrophobic interactions, and inhibit pro‐inflammatory cytokines. In DSS‐induced UC mice, SeNSs reduce inflammation, tissue damage, and disease activity by modulating cytokine, chemokine, and ...

Cystatin F is a biomarker of prion pathogenesis in mice.

open access: yesPLoS ONE, 2017
Misfolding of the cellular prion protein (PrPC) into the scrapie prion protein (PrPSc) results in progressive, fatal, transmissible neurodegenerative conditions termed prion diseases.

The Neutral Sphingomyelinase Pathway Regulates Packaging of the Prion Protein into Exosomes*

open access: yesJournal of Biological Chemistry, 2014
Background: Exosomes are a novel mechanism of intercellular transmission of infectious prions. Results: Chemical and RNAi inhibition of the neutral sphingomyelinase (nSMase) pathway impairs exosome formation and prion packaging.

Prion protein in ESC regulation [PDF]

open access: yesPrion, 2011
A large number of studies have analysed the putative functions of the prion protein (PrP(C)) in mammals. Although its sequence conservation over a wide range of different animals may indicate that this protein could have a key role in prion diseases, an absolutely accepted involvement has not been found so far.

Solving the Amyloid Paradox: Unveiling the Complex Pathogenicity of Amyloid Fibrils

open access: yesAggregate, EarlyView.
This review addresses the gap between strong evidence for the involvement of amyloid fibrils in neurodegeneration and the failure of anti‐amyloid therapies, a phenomenon herein termed the “amyloid paradox.” To address this paradox, we provide a comprehensive summary of the current understanding of fibrils' pathogenic properties and mechanisms ...

Prion propagation can occur in a prokaryote and requires the ClpB chaperone

open access: yeseLife, 2014
Prions are self-propagating protein aggregates that are characteristically transmissible. In mammals, the PrP protein can form a prion that causes the fatal transmissible spongiform encephalopathies.
