Alpha-synuclein (aSyn) plays a major role in Parkinson’s disease. Inhibition of stearoyl-CoA desaturase (SCD) reduces levels of mono-unsaturated C16 and C18 fatty acids, which are involved in aSyn toxicity in vitro and in vivo. The ratio of mono-unsaturated to saturated fatty acids (fatty acid desaturase index (FA-DI)) in plasma after SCD-inhibition correlates with effects on brain FA-DI. However, the FA-DI normal values and the inter- and intra-day variation in PD-patients and healthy subjects is unknown. Ten PD-patients (54 –73 years) and ten age-matched healthy subjects were included. On three consecutive days, fatty acids fractions and concentrations were measured throughout the day. Outcomes are expressed as estimated mean, and the coefficient of variation (CV%) in percentage. For C16 FA-DI, the inter-subject CV% was 20.7 % in healthy subjects, and 37.7 % in PD-patients. The intra-subject CV% over days was 14.0 % in healthy subjects, and 14.2 % in PD-patients, and within days 5.1 % in healthy subjects, and 5.9 % in PD-patients. For C18 FA-DI, the inter-subject CV% was 14.8 % in healthy subjects, and 16.0 % in PD-patients. The intra-subject CV% over days was 11.0 % in healthy subjects, and 8.6 % in PD-patients, and within days 8.4 % in healthy subjects, and 6.7 % in PD-patients. The observed extent of variability in healthy subjects and PD-patients support C16 and C18 FA-DI as suitable biomarkers to demonstrate target engagement in plasma, of for example SCD-inhibitors, in both healthy subjects and PD-patients.</div></div>","PeriodicalId":52767,"journal":{"name":"Biomarkers in Neuropsychiatry","volume":"13 ","pages":"Article 100132"},"PeriodicalIF":0.0,"publicationDate":"2025-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144470218","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Individuals diagnosed with depression (n = 23) and healthy controls (n = 31) were included in the study. A 15-minute sustained attention task (subtest of the Test Battery for Attention, version 2.3.1) was administered with concurrent electroencephalographic recordings to evaluate P300 amplitude and latency. Peripheral inflammation was assessed by measuring IL-6, IL-1β, and TNF-α levels. Perceived fatigue was assessed using the German version of the Fatigue Impact Scale. Generalized linear models (GLM) were used to evaluate the main aims of the study. Results indicated that depression was associated with reduced P300 amplitudes (p = 0.011), and age was significantly associated with P300 amplitude, with older participants showing reductions (p = 0.016). However, no significant effects of inflammatory markers on P300 components were found. While no group differences were observed in the total number of hits, both perceived fatigue (p = 0.033) and TNF-α (p = 0.007) were significantly associated with hit accuracy. A post-hoc mediation analysis explored that perceived fatigue mediates the relationship between depression and number of hits. These findings suggest that low-grade inflammation may not directly influence P300 components, though inflammation and fatigue appear linked to accuracy deficits. Finally, the impact of depression on the number of hits is primarily mediated by perceived fatigue, suggesting that fatigue is a crucial factor in how depression affects cognition.</div></div>","PeriodicalId":52767,"journal":{"name":"Biomarkers in Neuropsychiatry","volume":"12 ","pages":"Article 100121"},"PeriodicalIF":0.0,"publicationDate":"2025-02-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143387470","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
