Abstract:
Multiple system atrophy (MSA) is a rapidly progressive, fatal neurodegenerative disease of uncertain aetiology that belongs to the family of α-synucleinopathies. It clinically presents with parkinsonism, cerebellar, autonomic, and motor impairment in variable combinations. Pathological hallmarks are fibrillary α-synuclein (αSyn)-rich glial cytoplasmic inclusions (GCIs) mainly involving oligodendroglia and to a lesser extent neurons, inducing a multisystem neurodegeneration, glial activation, and widespread demyelinization. The neuronal αSyn pathology of MSA has molecular properties different f

Abstract:
Generating a prion with exogenously produced recombinant prion protein is widely accepted as the ultimate proof of the prion hypothesis. Over the years, a plethora of misfolded recPrP conformers have been generated, but despite their seeding capability, many of them have failed to elicit a fatal neurodegenerative disorder in wild-type animals like a naturally occurring prion. The application of the protein misfolding cyclic amplification technique and the inclusion of non-protein cofactors in the reaction mixture have led to the generation of authentic recombinant prions that fully recapitulat

Abstract:
Transmissible spongiform encephalopathies (TSEs) are fatal, untreatable neurodegenerative diseases. While the impact of TSEs on human health is relatively minor, these diseases are having a major influence on how we view, and potentially treat, other more common neurodegenerative disorders. Until recently, TSEs encapsulated a distinct category of neurodegenerative disorder, exclusive in their defining characteristic of infectivity. It now appears that similar mechanisms of self-propagation may underlie other proteinopathies such as Alzheimer’s disease, Parkinson’s disease, Amyotrophic lateral

Abstract:
Parkinson’s disease (PD) is the world’s second most common neurodegenerative disease and most common movement disorder. Characterised by a loss of dopaminergic neurons and the development of intraneuronal inclusions known as Lewy bodies, it has classically been thought of as a cell-autonomous disease. However, in 2008, two groups reported the startling observation of Lewy bodies within embryonic neuronal grafts transplanted into PD patients little more than a decade previously, suggesting that PD pathology can be propagated to neighbouring cells and calling basic assumptions of our understandi

Abstract:
Prions are self-propagating alternative states of protein domains. They are linked to both diseases and functional protein roles in eukaryotes. Prion-forming domains in Saccharomyces cerevisiae are typically domains with high intrinsic protein disorder (i.e., that remain unfolded in the cell during at least some part of their functioning), that are converted to self-replicating amyloid forms. S. cerevisiae is a member of the fungal class Saccharomycetes, during the evolution of which a large population of prion-like domains has appeared. It is still unclear what principles might govern the mol

Abstract:
Prion disease is a fatal neurodegenerative disorder caused by a deleterious prion protein (PrPSc). However, prion disease has not been reported in horses during outbreaks of transmissible spongiform encephalopathies (TSEs) in various animals in the UK. In previous studies, single nucleotide polymorphisms (SNPs) in the prion protein gene (PRNP) have been significantly associated with susceptibility to prion disease, and strong linkage disequilibrium (LD) between PRNP and prion-like protein gene (PRND) SNPs has been identified in prion disease-susceptible species.

Olfactory impairment is considered an initial disturbance of several neurodegenerative diseases (NDs), including Parkinson’s disease (PD) and Alzheimer’s disease (AD). In addition, smell impairment precedes a decade, or even longer, the onset of motor or cognitive symptoms. Olfactory signals are detected by olfactory receptor proteins (ORPs) expressed in the cilia of olfactory receptor neurons (ONs). ONs are the distinctive cellular components of the peripheral olfactory epithelium (OE) and lie in the nasal vault. ONs axons pass the cribriform plate and reach the olfactory bulb (OB) where th

Neurodegenerative diseases (NDDs) are growing in frequency and represent a major threat to public health. Advances in scientific progress have made it clear that NDDs share many underlying processes, including shared intracellular mechanisms such as protein misfolding and aggregation, cell-to-cell prion-like spread, growth factor signaling abnormalities, RNA and DNA disturbances, glial cell changes, and neuronal loss. Transmitter deficits are shared across many types of disorders. Means of studying NDDs with human iPS cells and transgenic models are similar. The progression of NDDs through asy

Abstract:
Prion disorders, or transmissible spongiform encephalopathies (TSEs), are universally fatal human and animal diseases that cause rapid degeneration of brain neurons by way of a conformational change in the prion protein that autocatalyzes further conformational change and selective neuronal toxicity. TSEs may occur sporadically, be inherited, or, least frequently, spread like an infectious agent. Mounting evidence suggests that degenerative proteinopathies such as Alzheimer disease and Parkinson disease may also involve prionlike spread of abnormal proteins between neurons but not between orga

Fatal familial insomnia (FFI) is a rare autosomal dominant genetic disease characterized by progressive insomnia, autonomic hyperactivity, memory deficits, hallucinations, and myoclonus. Unlike its name, insomnia is not the most common initial presentation in patients with FFI. More common features like autonomic hyperactivity (hypertension and tachycardia) are often missed, delaying the diagnosis of FFI. Genetic analysis of FFI shows a D178N-129M mutation that results in generation of insoluble proteins (prion proteins) that aggregate to form amyloid plaques, leading to deterioration of the c
