Prion agents occur in strains that are encoded by the structure of the misfolded prion protein (PrPSc). Prion strains can influence disease phenotype and the potential for interspecies transmission.

The Exceptions to the Central Dogma of Biology—Bending the Rules and Extending the Scope
ABSTRACT The central dogma is an organizing framework for how information flows in biological systems. First presented in 1957 by Francis Crick in his talk “On Protein Synthesis” as a fundamental hypothesis of how information is transferred from DNA to proteins but not out of proteins, it is now introduced in cell biology textbooks as three sequential ...

Evidence of scrapie transmission via milk
Background The risk of scrapie infection increases with increased duration and proximity of contact between sheep at lambing. Scrapie infectivity has not been detected in milk but cellular prion protein, the precursor of disease-associated prion protein ...

Classical BSE prions emerge from asymptomatic pigs challenged with atypical/Nor98 scrapie
Pigs are susceptible to infection with the classical bovine spongiform encephalopathy (C-BSE) agent following experimental inoculation, and PrPSc accumulation was detected in porcine tissues after the inoculation of certain scrapie and chronic wasting ...

TDP‐43 Aggregation: The Healthy‐Toxic Balance of the Prion‐Like Domain
TDP‐43 function relies on a delicate balance between reversible phase‐separated states and irreversible aggregation. Under physiological conditions, TDP‐43 forms dynamic droplets and oligomers that support normal cellular functions. In pathological contexts, this balance shifts toward aberrant aggregation, leading to toxic species.

Genotyping and surveillance for scrapie in Finnish sheep
Background The progression of scrapie is known to be influenced by the amino acid polymorphisms of the host prion protein (PrP) gene. There is no breeding programme for TSE resistance in sheep in Finland, but a scrapie control programme has been in place

The limits of test-based scrapie eradication programs in goats. [PDF]
Small ruminant post-mortem testing programs were initially designed for monitoring the prevalence of prion disease. They are now considered as a potential alternative to genetic selection for eradicating/controlling classical scrapie at population level.

Incidence of infection in Prnp ARR/ARR sheep following experimental inoculation with or natural exposure to classical scrapie. [PDF]
The prion protein gene (Prnp) is highly influential in determining risk and susceptibility of sheep exposed to classical scrapie. Sheep homozygous for alanine at codon 136 and arginine at codons 154 and 171 (ARR/ARR) of the Prnp gene are historically ...

HaloTag Fusion Enables Dynamic Analysis of Prion Protein Biosynthesis, Turnover, and Misfolding
Prion protein (PrP) misfolding underlies fatal neurodegenerative diseases. We developed a HaloTag‐based PrP fusion enabling spatiotemporal labeling of distinct PrP populations in living cells. This system recapitulates native PrP biology, reveals early misfolding events in disease‐associated mutants, and allows mechanistic interrogation of PrP‐lowering
