| Popis | ?-Synuclein (?-Syn) aggregation and fibrillation are pathological hallmarks of several neurodegenerative disorders, collectively termed synucleinopathies. The misfolded ?-Syn protein exhibits a prion-like seeding behavior, promoting misfolding, intracellular spread, and progressive neurodegeneration. Recent advances in structural biology have revealed critical insights into the conformational heterogeneity of ?-Syn aggregates and their strain-specific properties across distinct synucleinopathies. In parallel, significant progress has been made in biomarker development, particularly with the arrival of seed amplification assays. Among these, Real-Time Quaking-Induced Conversion (RT-QuIC) has emerged as a highly sensitive, specific, and scalable method for detecting pathogenic ?-Syn species in cerebrospinal fluid and other tissues. This review summarizes the latest findings from structural studies on ?-Syn oligomers and aggregates, their relevance to disease mechanisms, and highlights RT-QuIC as the most clinically advanced and rapidly evolving assay. We discuss its potential for early, biomarker-driven diagnostics, patient stratification, and clinical implementation. |
