Loss of Octarepeats in Two Processed Prion Pseudogenes in the Red Squirrel, Sciurus vulgaris [PDF]

, 2010
The N-terminal region of the mammalian prion protein (PrP) contains an 'octapeptide' repeat which is involved in copper binding. This eight- or nine-residue peptide is repeated four to seven times, depending on the species, and polymorphisms in repeat ...

Syntaxin-6 delays prion protein fibril formation and prolongs the presence of toxic aggregation intermediates

eLife
Prions replicate via the autocatalytic conversion of cellular prion protein (PrPC) into fibrillar assemblies of misfolded PrP. While this process has been extensively studied in vivo and in vitro, non-physiological reaction conditions of fibril formation

Immunomodulation for prion and prion-related diseases [PDF]

Expert Review of Vaccines, 2010
Prion diseases are a unique category of illness, affecting both animals and humans, where the underlying pathogenesis is related to a conformational change of a normal self protein called cellular prion protein to a pathological and infectious conformer known as scrapie prion protein (PrP(Sc)). Currently, all prion diseases lack effective treatment and

Prion protein in the cerebrospinal fluid of healthy and naturally scrapie-affected sheep [PDF]

, 2006
The aim of this study was to characterize the cerebrospinal fluid (CSF) prion protein (PrP) of healthy and naturally scrapie-affected sheep. The soluble form of CSF PrPC immunoblotted with an anti-octarepeat and an anti-C terminus mAb showed two isoforms

A novel protective prion protein variant that colocalizes with kuru exposure. [PDF]

, 2009
BACKGROUND: Kuru is a devastating epidemic prion disease that affected a highly restricted geographic area of the Papua New Guinea highlands; at its peak, it predominantly affected adult women and children of both sexes.

Canine detection of chronic wasting disease (CWD) in laboratory and field settings

Prion, 2023
Chronic wasting disease (CWD) is a fatal transmissible spongiform encephalopathy that affects both free-ranging and farmed cervid species, including mule deer, white-tailed deer, and elk (Odocoileus hemionus, Odocoileus virginianus, and Cervus canadensis)

Effects of post-translational modifications on prion protein aggregation and the propagation of scrapie-like characteristics in vitro [PDF]

, 2007
Prion diseases, or transmissible spongiform encephalopathies (TSEs) are typically characterised by CNS accumulation of PrPSc, an aberrant conformer of a normal cellular protein PrPC.

Serial changes in regional cerebral blood flow in Gerstmann–Sträussler–Scheinker disease caused by a Pro-to-Leu mutation at codon 105 in the prion protein gene

Prion, 2023
Gerstmann–Sträussler–Scheinker disease with a Pro-to-Leu substitution at codon 105 in the prion protein gene (GSS-P105L) is a rare variant of human genetic prion disease.

From energy provision to protein synthesis: Tunnelling nanotubes as mediators of intercellular metabolic cooperation in cancer

FEBS Open Bio, EarlyView.
The cytoskeleton‐mediated transport of mitochondria via tunnelling nanotubes restores respiration, increases ATP production, rescues cells from apoptosis, activates the AKT/mTOR signalling pathway, promotes cell migration and invasiveness, contributes to cancer progression and treatment resistance.

Expression of the cellular prion protein by mast cells in the human carotid body

Prion, 2023
Prion diseases are fatal neurologic disorders that can be transmitted by blood transfusion. The route for neuroinvasion following exposure to infected blood is not known.
