Molecularly Engineered Phenoxazinone‐Skeleton Cascade‐Activated NIR Probes for Monitoring Fe2+/Viscosity in Ferroptosis‐Mediated Parkinson's Disease

Advanced Science, EarlyView.
A series of Fe2+/viscosity cascade‐activated NIR fluorescence probes (NP1–5) are synthesized, and NP3 is selected for its optimal properties. To verify application of NP3 in ferroptosis intervention in PD, PQR NPs, is constructed by NP3 and quercetin self‐assembling.

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.

Association between Plasma P‐tau217 and Alzheimer's Copathology and Cognitive Decline in Parkinson's Disease

Annals of Neurology, EarlyView.
Objective Clinically relevant Alzheimer's disease co‐pathology is common in Lewy body disorders. Plasma P‐tau217 is a sensitive biomarker for amyloid and tau pathology in Alzheimer's disease. The objective was to determine if plasma P‐tau217 associates with Alzheimer's disease co‐pathology and cognition in Lewy body disorders. Methods Participants had (

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.

Predominance of Ferroptotic Cell Death Mechanisms in Substantia Nigra Neurodegeneration in Parkinson's Disease

Annals of Neurology, EarlyView.
Objective The extent of neuronal loss in Parkinson's disease (PD) and the pathogenic processes underlying neuronal dysfunction and loss remain poorly understood. Here, we analyzed the expression of key molecules representing different cell death signaling pathways and their association with Lewy pathology, dopaminergic (DA) neuron loss and stage of PD ...

Nanomaterial‐Mediated Near‐Infrared Photothermal Neuromodulation for Neurologic Disorders

Advanced NanoBiomed Research, EarlyView.
This review summarizes how near‐infrared light activates photothermal nanomaterials to enable noninvasive neuromodulation with high spatiotemporal precision. It elucidates the underlying mechanisms, explores targeted therapeutic applications for neurological disorders, discusses integration with optogenetics and biosensors, and addresses future ...

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 ...

Rab1A Over-Expression Prevents Golgi Apparatus Fragmentation and Partially Corrects Motor Deficits in an Alpha-Synuclein Based Rat Model of Parkinson's Disease

Journal of Parkinson’s Disease, 2011
Although the overabundance of human alpha-synuclein in nigral dopaminergic neurons is considered to play a pathogenic role in Parkinson's disease (PD), it remains unclear how alpha-synuclein leads to neuronal degeneration and motor symptoms.

Exosomal cell-to-cell transmission of alpha synuclein oligomers

Molecular Neurodegeneration, 2012
Background Aggregation of alpha-synuclein (αsyn) and resulting cytotoxicity is a hallmark of sporadic and familial Parkinson’s disease (PD) as well as dementia with Lewy bodies, with recent evidence implicating oligomeric and pre-fibrillar forms of αsyn ...
