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.

Oncogenic KRAS Rewires Stress Granule Dynamics: Mechanisms and Therapeutic Opportunities

The Kaohsiung Journal of Medical Sciences, EarlyView.
ABSTRACT Stress granules (SGs) are dynamic, membrane‐less structures that form in response to various cellular stresses, including metabolic, oxidative, and therapeutic challenges. They function as adaptive hubs and reorganize protein synthesis and signaling networks to help cells survive under stress. In cancer, these condensates are often hijacked to

Endogenous Viral Etiology of Prion Diseases

, 2009
Transmissible spongiform encephalopathies (TSEs), or prion diseases, are a group of incurable neurodegenerative disorders, including Kuru and Creutzfeldt-Jakob disease in humans, “mad cow” disease in cattle, and scrapie in sheep. This paper

Analysis of the hippocampal proteome in ME7 prion disease reveals a predominant astrocytic signature and highlights the brain-restricted production of clusterin in chronic neurodegeneration

, 2014
Prion diseases are characterized by accumulation of misfolded protein, gliosis, synaptic dysfunction, and ultimately neuronal loss. This sequence, mirroring key features of Alzheimer disease, is modeled well in ME7 prion disease.

Co‐ and Multi‐Pathologies in Parkinson's Disease: An International Parkinson and Movement Disorder Society Scientific Issues Committee Review

Movement Disorders, EarlyView.
Abstract Parkinson's disease (PD) has been historically defined as a disease of striatal dopamine deficiency secondary to degeneration of dopaminergic neurons in the substantia nigra pars compacta, related to the presence of Lewy bodies and Lewy neurites.

Aqueous extraction of formalin-fixed paraffin-embedded tissue and detection of prion disease using real-time quaking-induced conversion

BMC Research Notes
Objective The goal of the research presented here is to determine if methods previously developed for the aqueous extraction of PrPSc from formalin-fixed paraffin-embedded tissue (FFPET) are applicable to the detection PrPSc by real-time quaking induced ...

Genetic Variation and Strain Dynamics in Chronic Wasting Disease

Viruses
Chronic wasting disease (CWD) is a prion disease of cervids marked by growing strain diversity and variation in host susceptibility. Central to this complexity are prion protein gene (Prnp) polymorphisms, which can modulate pathogenesis by altering the ...

Raman optical activity demonstrates poly(L-proline) II helix in the N-terminal region of the ovine prion protein: Implications for function and misfunction

, 2004
The aqueous solution structure of the full-length recombinant ovine prion protein PrP25-233, together with that of the N-terminal truncated version PrP94-233, have been studied using vibrational Raman optical activity (ROA) and ultraviolet circular ...

Spatiotemporal Progression Patterns of Striatal Dopamine Depletion and Cerebral Hypoperfusion in Parkinson's Disease

Movement Disorders, EarlyView.
Abstract Background The identification of Parkinson's disease (PD) subtypes is crucial for predicting the disease course and designing personalized therapeutic strategies. Objectives The aim of the study was to characterize the heterogeneity of the spatiotemporal evolutionary patterns of striatal dopamine depletion and cerebral hypoperfusion in PD ...
