Seeing Invisible Oligomers: Rethinking α‐Synuclein Pathology Through Proximity Ligation Assay

Movement Disorders, EarlyView.
Abstract Parkinson's disease (PD) and multiple system atrophy are defined by α‐synuclein (αSYN)‐positive inclusions – Lewy bodies (LBs) and glial cytoplasmic inclusions – yet mounting evidence indicates that these inclusions represent only a fraction of disease‐relevant pathology.

Heterogenous Neuropathology in a Pedigree with RAB39B‐Related Parkinson's Disease

Movement Disorders, EarlyView.
Abstract Background In 2015, we reported a family with Parkinson's disease resulting from the RAB39B p.G192R (c.574G>A) variant. Since then, two affected brothers from the family have undergone autopsy. Objectives To characterize neuropathological findings, assess intracellular distribution of RAB39B protein, and examine the effect of p.G192R on α ...

Synaptic phosphorylated a-synuclein in dementia with Lewy bodies [PDF]

, 2017
Dementia with Lewy bodies is characterized by the accumulation of Lewy bodies and Lewy neurites in the CNS, both of which are composed mainly of aggregated a-synuclein phosphorylated at Ser129.

Progression of Motor and Cognitive Functions in Isolated REM Sleep Behavior Disorder: A 7‐Year Prospective Matched Cohort Study

Movement Disorders, EarlyView.
Abstract Background Although clinical markers (eg, motor and cognitive impairment) in isolated rapid eye movement sleep behavior disorder (iRBD) are associated with faster phenoconversion, their longitudinal trajectory patterns (linear or nonlinear) remain unclear.

Gray Matter Microstructure Measured Using Diffusion Imaging as a Biomarker of Severity in Lewy Body Diseases

Movement Disorders, EarlyView.
Abstract Background Despite widespread cortical involvement in Lewy body diseases, conventional gray matter magnetic resonance imaging (MRI) shows limited sensitivity. Diffusion‐weighted MRI‐derived microstructural measures have shown utility in Alzheimer's disease, but their application across the Lewy body disease spectrum remains limited ...

The GBA1 p.E427K (p.E388K) Variant Is a Risk Factor for Synucleinopathies: A Meta‐Analysis

Movement Disorders, EarlyView.
Abstract Background Variants in GBA1 are important genetic risk factors for synucleinopathies, including Parkinson's disease (PD). Although several GBA1 variants are established risk or severity modifiers, the role of the p.E427K variant remains unclear.

Rare‐Variant Burden across Lysosomal Genes Implicates Sialylation and Ganglioside Metabolism in Parkinson's Disease

Movement Disorders, EarlyView.
Abstract Background Lysosomal dysfunction is central to Parkinson's disease (PD) pathogenesis, with GBA1 representing the strongest established genetic risk factor. Numerous other genes involved in lysosomal sphingolipid, glycosphingolipid, and ceramide metabolism have been proposed as contributors to PD, highlighting the need for genetic analyses ...
