Alpha Synuclein Toxicity and Non-Motor Parkinson’s

Cells
Parkinson’s disease (PD) is a common multisystem neurodegenerative disorder affecting 1% of the population over the age of 60 years. The main neuropathological features of PD are the loss of dopaminergic neurons in the substantia nigra pars compacta ...

GM1 Ganglioside Modifies α-Synuclein Toxicity and is Neuroprotective in a Rat α-Synuclein Model of Parkinson\u27s Disease. [PDF]

, 2019
While GM1 may interact with α-synuclein in vitro to inhibit aggregation, the ability of GM1 to protect against α-synuclein toxicity in vivo has not been investigated.

The Emerging Parkinson's Disease Oxylipin‐Ome

Advanced Science, EarlyView.
ABSTRACT Parkinson Disease (PD) is increasingly considered a proteinopathy and lipidopathy. This proteinopathy+lipidopathy paradigm has been further refined to a fatty acid (FA)‐opathy, centering dysregulated FA metabolism as fundamental in PD lipid dysfunction.

Orthogonal Ionic Liquid‐Based Extraction Strategy Enables Amyloid‐Specific Profiling of Aggregate Proteome

Advanced Science, EarlyView.
An orthogonal ionic‐liquid extraction (Orth‐iEA) enables selective isolation of amyloid fibrils. TMGBF4 disrupts hydrogen‐bonded β‐sheet networks to solubilize amyloid aggregates, whereas C12ImCl interacts with hydrophobic regions of non‐amyloid proteins.

Depopulation of dense α-synuclein aggregates is associated with rescue of dopamine neuron dysfunction and death in a new Parkinson's disease model.

, 2019
Parkinson's disease (PD) is characterized by the presence of α-synuclein aggregates known as Lewy bodies and Lewy neurites, whose formation is linked to disease development. The causal relation between α-synuclein aggregates and PD is not well understood.

Nanoplastics and Neurodegeneration: A Roadmap From Mechanism to Causation

Advanced Science, EarlyView.
Nanoplastics are pervasive environmental contaminants with potentially profound implications for human health. Emerging evidence suggests a possible link between nanoplastic exposure and neurodegeneration, a key driver of ageing and dementia, yet causality remains unresolved.

α-Synuclein conformational strains spread, seed and target neuronal cells differentially after injection into the olfactory bulb

Acta Neuropathologica Communications, 2019
Alpha-synuclein inclusions, the hallmarks of synucleinopathies, are suggested to spread along neuronal connections in a stereotypical pattern in the brains of patients.

Equine models in translational medicine: A comparative approach to human health

Animal Models and Experimental Medicine, EarlyView.
This diagram summarizes and contrasts rodent and equine models, outlining their strengths, limitations, and applications. Horses offer naturally occurring diseases, genetic and physiological similarities to humans, and suitability for longitudinal and clinical‐scale studies.

Alpha-synuclein inclusions reduced by PIKfyve inhibition in Parkinson disease cell models

Neurobiology of Disease
Objective: Parkinson's disease (PD) pathophysiology is associated with a progressive loss of dopaminergic neurons in the substantia nigra and accumulation of insoluble inclusions of misfolded alpha-synuclein.
