Prion neurotoxicity

Brain Pathology, 2019
AbstractAlthough the mechanisms underlying prion propagation and infectivity are now well established, the processes accounting for prion toxicity and pathogenesis have remained mysterious. These processes are of enormous clinical relevance as they hold the key to identification of new molecular targets for therapeutic intervention.

Human Brain Contusions Contain Pathogenic Transmissible Species that Induce Progressive Cognitive Decline and Tau Pathology in Mice

Annals of Neurology, EarlyView.
Objective Traumatic brain injury (TBI) is an established risk factor for dementia, although the underlying mechanisms remain unclear. Our previous research demonstrated that a single severe TBI in wild‐type (WT) mice induces a prion‐like form of tau (tauTBI) that spreads throughout the brain, leading to memory deficits.

Prion Diseases [PDF]

Continuum, 2015
This article presents an update on the clinical aspects of human prion disease, including the wide spectrum of their presentations.Prion diseases, a group of disorders caused by abnormally shaped proteins called prions, occur in sporadic (Jakob-Creutzfeldt disease), genetic (genetic Jakob-Creutzfeldt disease, Gerstmann-Sträussler-Scheinker syndrome ...

Enhanced Sensitivity of a Modified Quaking‐Induced Conversion Diagnostic Test for the Broad Detection of Sporadic and Inherited Prion Diseases: A Retrospective Study

Annals of Neurology, EarlyView.
Objective Quaking‐induced conversion (QuIC) tests, which detect prion‐seeding activity in cerebrospinal fluid (CSF), have markedly advanced the antemortem diagnosis of prion diseases such as Creutzfeldt‐Jakob disease (CJD). These tests provide high diagnostic accuracy and enable timely differentiation from other rapidly progressive neurodegenerative ...

Detection of chronic wasting disease prions in soil at an illegal white-tailed deer carcass disposal site

Prion
Chronic wasting disease (CWD) is a contagious prion disorder affecting cervids such as deer, elk, caribou, and moose, causing progressive and severe neurological degeneration followed by eventual death.

Osteological correlates of the respiratory and vascular systems in the neural canals of Mesozoic ornithurines Ichthyornis and Janavis

The Anatomical Record, EarlyView.
Abstract In birds, the neural canal houses a variety of anatomical structures including the spinal cord, meninges, spinal vasculature, and respiratory diverticula. Among these, paramedullary diverticula and the extradural dorsal spinal vein may leave behind osteological correlates in the form of pneumatic foramina and fossae, and a bilobed geometry of ...

Analysis of Single Particles of Amyloid Beta and α‐Synuclein With Seeded Amplification for the Diagnosis of Alzheimer's and Parkinson's Disease

Biotechnology and Applied Biochemistry, EarlyView.
ABSTRACT Neurodegenerative diseases, including Alzheimer's disease (AD) and Parkinson's disease (PD), are characterized by the pathological aggregation of specific proteins such as amyloid beta (Aβ) and α‐synuclein, respectively. Early detection of these protein aggregates in biological fluids could facilitate timely diagnosis and therapeutic ...

The power of many: when genetics met yeasts and high‐throughput

Biological Reviews, EarlyView.
ABSTRACT In recent years, complex technological capabilities have evolved, driven by the need to solve complex and integrative biological questions through global analyses. New equipment allows the scaling up and automation of processes which previously were carried out on a very limited scale.
