Prions [PDF]

open access: yesProceedings of the National Academy of Sciences, 1984
Prions are unprecedented infectious pathogens that cause a group of invariably fatal neurodegenerative diseases by an entirely novel mechanism. Prion diseases may present as genetic, infectious, or sporadic disorders, all of which involve modification of the prion protein (PrP).

Efficient interspecies transmission of synthetic prions.

open access: yesPLoS Pathogens, 2021
Prions are comprised solely of PrPSc, the misfolded self-propagating conformation of the cellular protein, PrPC. Synthetic prions are generated in vitro from minimal components and cause bona fide prion disease in animals.

Selective propagation of mouse-passaged scrapie prions with long incubation period from a mixed prion population using GT1-7 cells. [PDF]

open access: yesPLoS ONE, 2017
In our previous study, we demonstrated the propagation of mouse-passaged scrapie isolates with long incubation periods (L-type) derived from natural Japanese sheep scrapie cases in murine hypothalamic GT1-7 cells, along with disease-associated prion ...

MicroRNAs and depression

open access: yesNeurobiology of Disease, 2012
With an estimated life-time prevalence of 15 to 17% and an incapacitating illness in 50% of cases, depressive spectrum disorders represent a heavy public health burden.

Prions and Prion-like Proteins [PDF]

open access: yesJournal of Biological Chemistry, 2014
Prions are self-replicating protein aggregates and are the primary causative factor in a number of neurological diseases in mammals. The prion protein (PrP) undergoes a conformational transformation leading to aggregation into an infectious cellular pathogen.

Microbial Composition, Disease Trajectory and Genetic Background in a Slow Onset Model of Frontotemporal Lobar Degeneration

open access: yesBiomolecules
Slow-onset neurodegenerative disease in a low-expresser 2N4R P301L transgenic (Tg) mouse model is marked by neuroinflammation and by differing patterns of CNS deposition and accumulation of tau conformers, with such heterogeneities present even within ...

Immunomodulation for prion and prion-related diseases [PDF]

open access: yesExpert 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

Plants as vectors for environmental prion transmission

open access: yesiScience, 2023
Summary: Prions cause fatal neurodegenerative diseases and exhibit remarkable durability, which engenders a wide array of potential exposure scenarios. In chronic wasting disease of deer, elk, moose, and reindeer and in scrapie of sheep and goats, prions

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

open access: yesFEBS 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.

Seizures are a druggable mechanistic link between TBI and subsequent tauopathy

open access: yeseLife, 2021
Traumatic brain injury (TBI) is a prominent risk factor for dementias including tauopathies like chronic traumatic encephalopathy (CTE). The mechanisms that promote prion-like spreading of Tau aggregates after TBI are not fully understood, in part due to
