Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective To characterize the demographic, clinical, and laboratory features of the Chinese patients of genetic Creutzfeldt‐Jakob disease with T188K variant (T188K‐gCJD), the most common subtype of genetic prion diseases (gPrDs) in China. Methods In this nationwide retrospective study, data from 98 genetically confirmed T188K‐gCJD patients ...

Bioassays and inactivation of prions
Cold Spring Harbor Perspectives in Biology, 2017 The experimental study of prions requires a model for their propagation. However, because prions lack nucleic acids, the simple techniques used to replicate the propagation of bacteria and viruses are not applicable.

Characterizing Cutaneous α‐Synuclein Deposition and Seeding Activity in Parkinson's Disease Subtypes
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Cutaneous phosphorylated α‐synuclein (p‐syn) and α‐synuclein seeding activity are promising biomarkers for Parkinson's disease (PD), but their clinical value remains uncertain due to disease heterogeneity. This study evaluates these two biomarkers in PD patients to inform phenotype‐specific diagnosis and disease severity assessment ...

Detection of prions in blood from patients with variant Creutzfeldt-Jakob disease
Science Translational Medicine, 2016 Prions can be detected in blood from patients with variant Creutzfeldt-Jakob disease with high sensitivity and specificity. A new blood test for prion diseases Prions are the proteinaceous infectious agents responsible for various animal and human ...

Stage‐Dependent β‐Synuclein Links MRI and Cognitive Decline in Alzheimer's Disease
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Synaptic degeneration drives cognitive decline in Alzheimer's disease (AD), but synaptic biomarkers are scarce. Brain‐enriched β‐synuclein emerged as a synaptic damage marker. We investigated its diagnostic, prognostic, and structural correlates across the AD continuum.

Bioengineering & Translational MedicineSynucleinopathies, including Parkinson's disease (PD), multiple system atrophy (MSA), and dementia with Lewy bodies (DLB), are neurodegenerative disorders caused by the accumulation of misfolded alpha‐synuclein protein.

Prions Ex Vivo: What Cell Culture Models Tell Us about Infectious Proteins
International Journal of Cell Biology, 2013 Prions are unconventional infectious agents that are composed of misfolded aggregated prion protein. Prions replicate their conformation by template-assisted conversion of the endogenous prion protein PrP.

Aerosols transmit prions to immunocompetent and immunodeficient mice. [PDF]
PLoS Pathogens, 2011 Prions, the agents causing transmissible spongiform encephalopathies, colonize the brain of hosts after oral, parenteral, intralingual, or even transdermal uptake. However, prions are not generally considered to be airborne.

Conformational diversity in purified prions produced in vitro.
PLoS Pathogens, 2023 Prion diseases are caused by misfolding of either wild-type or mutant forms of the prion protein (PrP) into self-propagating, pathogenic conformers, collectively termed PrPSc.
