Yakugaku Zasshi, 2019 Pathological α-synuclein (αSyn) has been shown to retain the ability to propagate as prions in humans and animals. However, the molecular basis underlying the prion-like properties of αSyn remains poorly understood. We examined whether brain tissues from cases of dementia with Lewy bodies (DLB), which contain serine 129 (Ser129)-phosphorylated ...

Real-time quaking-induced conversion assay is accurate for Lewy body diseases: a meta-analysis
Neurological Sciences, 2022Real-time quaking-induced conversion (RT-QuIC) is a novel in vitro acellular seed amplification analysis and has been widely used to detect prion diseases. Due to the similar mechanism of abnormal aggregation of α-synuclein, RT-QuIC has great potential for diagnosing Lewy body diseases.

AbstractBackgroundAggregation of α‐synuclein (oligomeric α‐syn) has been considered as the pathological hallmark of Parkinson's disease (PD) and multiple system atrophy (MSA). Studies showed oligomeric α‐syn/total α‐syn ratio was increased in the saliva of patients with PD, suggesting that seeding activity of salivary oligomeric α‐syn may be a novel ...

Methods in Molecular Biology, 2018 A characteristic feature of transmissible spongiform encephalopathies (TSE) is the progressive accumulation of protein aggregates in the brain in a self-propagation manner. Based on this mechanism, in vitro protein amplification systems (such as real-time quaking-induced conversion (RT-QuIC)) for the detection of misfolded prion protein scrapie (PrPres)

Real-Time Quaking-Induced Conversion for Diagnosis of Prion Disease
2017Sporadic human prion diseases are defined on the basis of clinical features, with periodic sharp discharge (PSD) on electroencephalograms (EEG), a positive 14-3-3 protein assay of CSF samples, and abnormal signals on cerebral cortex on diffusion-weighted (DWI) MR images.

Prion diseases, a group of fatal neurodegenerative disorders, present significant diagnostic challenges due to their subtle clinical manifestations, which often mimic those of other treatable neurological conditions. This diagnostic ambiguity underscores the necessity for reliable and specific diagnostic tools.
