Condensate-driven triglyceride reduction links α-synuclein to mitochondrial dysfunction.

α-Synuclein reduces triglyceride levels and disrupts lipid droplet and mitochondrial structure, linking lipid metabolism to neurodegenerative toxicity in C. elegans.

• Why it matters: Understanding how α-synuclein interacts with lipids is crucial for uncovering mechanisms underlying neurodegenerative diseases like Parkinson's, where lipid dysregulation may drive cell damage.
• What they did: Lipidomic profiling of aging C. elegans revealed that α-synuclein decreases triacylglycerols and alters lipid droplet and mitochondrial integrity, with effects dependent on its lipid-binding and condensate-forming properties; interventions included genetic inhibition of long-chain unsaturated fatty acid synthesis and medium-chain triglyceride supplementation.
• The result: Findings suggest that α-synuclein-induced lipid remodeling contributes to cellular toxicity, and MCT supplementation offers a potential therapeutic strategy, supported by lower plasma TAGs observed in Parkinson's patients.
