BackgroundAggregation of -synuclein is a central pathological feature of Parkinsons disease (PD), yet reliable and broadly applicable fluid biomarkers reflecting disease-relevant -synuclein biology remain limited. We aimed to establish acetylated -synuclein (Ac-Syn), the predominant proteoform in vivo, as a novel biomarker for PD and to evaluate its diagnostic utility based on a sensitive immunoassay. MethodsUsing a single molecule array technique capable of quantitatively detecting N-terminall...
