A survey and a molecular dynamics study on the (central) hydrophobic region of prion proteins

, 2014
Prion diseases are invariably fatal neurodegenerative diseases that affect humans and animals. Unlike most other amyloid forming neurodegenerative diseases, these can be highly infectious. Prion diseases occur in a variety of species.

A cationic tetrapyrrole inhibits toxic activities of the cellular prion protein [PDF]

, 2016
Prion diseases are rare neurodegenerative conditions associated with the conformational conversion of the cellular prion protein (PrPC) into PrPSc, a self-replicating isoform (prion) that accumulates in the central nervous system of affected individuals.

Beyond Extracellular Vesicle (EV) Hype: Practical Solutions and Remaining Hurdles in EV Research, Manufacturing, and Clinical Translation

Advanced Science, EarlyView.
ABSTRACT Extracellular vesicles (EVs) are nanoscale mediators of intercellular communication with diverse molecular cargoes that reflect their cell of origin. Advances in isolation, detection, and single‐particle analytics have revealed increasing molecular and functional heterogeneity, while exposing limitations in how EV identity and activity are ...

Differentially Expressed MiRNAs and tRNA Genes Affect Host Homeostasis During Highly Pathogenic Porcine Reproductive and Respiratory Syndrome Virus Infections in Young Pigs

Frontiers in Genetics, 2019
Background: Porcine respiratory and reproductive syndrome virus (PRRSV) is a single-stranded RNA virus member that infects pigs and causes losses to the commercial industry reaching upward of a billion dollars annually in combined direct and indirect ...

Hofmeister Effect in RT-QuIC Seeding Activity of Chronic Wasting Disease Prions

Frontiers in Bioengineering and Biotechnology, 2021
Chronic wasting disease (CWD) is a transmissible spongiform encephalopathy (TSE) that causes a fatal neurodegenerative disease in cervids. Cases of CWD are rapidly increasing in North America among wild and farmed cervid populations, and potential for ...

Prion-induced neurotoxicity: Possible role for cell cycle activity and DNA damage response. [PDF]

, 2015
Protein misfolding neurodegenerative diseases arise through neurotoxicity induced by aggregation of host proteins. These conditions include Alzheimer's disease, Huntington's disease, Parkinson's disease, motor neuron disease, tauopathies and prion ...

Alzheimer's Disease Risk Factor APOE4 Exerts Dimorphic Effects on Female Bone

Advanced Science, EarlyView.
In aging bone, osteocytes accumulate neurodegenerative risk factor Apolipoprotein E (APOE). A humanized version of the Alzheimer's disease risk allele APOE4 altered the mouse bone transcriptome and proteome, with effects in female bone surpassing the brain, including bone fragility due to suppressed osteocytic maintenance of bone quality, identifying ...

Oxidative Damage to Nucleic Acids in Human Prion Disease

Neurobiology of Disease, 2002
Recently, several studies proposed a physiological role for the cellular prion protein (PrPc) in defense against oxidative stress. Since the pathogenesis of prion disease necessarily involves a disturbance of PrPc homeostasis, we hypothesized that such ...

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

, 2013
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.

The prion protein constitutively controls neuronal store-operated ca2+ entry through Fyn Kinase [PDF]

, 2015
The prion protein (PrPC) is a cell surface glycoprotein mainly expressed in neurons, whose misfolded isoforms generate the prion responsible for incurable neurodegenerative disorders.
