2.7 Å cryo-EM structure of ex vivo RML prion fibrils

open access: yesNature Communications, 2022
High-resolution structures of mammalian prions have remained elusive. Here, Manka et al. report the cryo-EM structure of infectious RML prion fibrils from mice.

Prion protein conversion at two distinct cellular sites precedes fibrillisation

open access: yesNature Communications, 2023
The self-templating nature of prions plays a central role in prion pathogenesis and is associated with infectivity and transmissibility. Since propagation of proteopathic seeds has now been acknowledged a principal pathogenic process in many types of ...

Essential Components of Synthetic Infectious Prion Formation De Novo

open access: yesBiomolecules, 2022
Prion diseases are a class of neurodegenerative diseases that are uniquely infectious. Whilst their general replication mechanism is well understood, the components required for the formation and propagation of highly infectious prions are poorly ...

Genetic Risk Factors of Creutzfeldt-Jakob Disease in the Population of Newborns in Slovakia

open access: yesPathogens, 2021
The most frequent human prion disease is Creutzfeldt–Jakob disease (CJD). It occurs as sporadic (sCJD), genetic (gCJD), iatrogenic (iCJD) form and as variant CJD.

Case report of homozygous E200D mutation of PRNP in apparently sporadic Creutzfeldt-Jakob disease

open access: yesBMC Neurology, 2021
Background Inherited prion diseases are rare autosomal dominant disorders associated with diverse clinical presentations. All are associated with mutation of the gene that encodes prion protein (PRNP).

The Future of Seed Amplification Assays and Clinical Trials

open access: yesFrontiers in Aging Neuroscience, 2022
Prion-like seeded misfolding of host proteins is the leading hypothesised cause of neurodegenerative diseases. The exploitation of the mechanism in the protein misfolding cyclic amplification (PMCA) and real-time quaking-induced conversion (RT-QuIC ...

Animal prion diseases: A review of intraspecies transmission [PDF]

open access: yesOpen Veterinary Journal, 2021
Animal prion diseases are a group of neurodegenerative, transmissible, and fatal disorders that affect several animal species. The causative agent, prion, is a misfolded isoform of normal cellular prion protein, which is found in cells with higher ...

Simultaneous expression of MMB-FOXM1 complex components enables efficient bypass of senescence

open access: yesScientific Reports, 2021
Cellular senescence is a stable cell cycle arrest that normal cells undergo after a finite number of divisions, in response to a variety of intrinsic and extrinsic stimuli. Although senescence is largely established and maintained by the p53/p21WAF1/CIP1

PRION DISEASES. PATHOGENS OF PRION DISEASES

open access: yesАктуальные проблемы теоретической и клинической медицины, 2023
Prion diseases are diseases associated with pathological proteins and based on a protein with an abnormal tertiary structure. Prions are a special class of infectious pathogens that do not have nucleic acids in their composition.

Computational Studies of the Structural Stability of Rabbit Prion Protein Compared to Human and Mouse Prion Proteins [PDF]

open access: yes, 2011
Prion diseases are invariably fatal and highly infectious neurodegenerative diseases affecting humans and animals. The neurodegenerative diseases such as Creutzfeldt-Jakob disease, variant Creutzfeldt-Jakob diseases, Gerstmann-Str$\ddot{a}$ussler ...
