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

α-Synuclein reduces triacylglycerols and disrupts lipid droplets and mitochondria in aging Caenorhabditis elegans, linking lipid metabolism to toxicity.

• Why it matters: Understanding how α-synuclein interacts with lipids is crucial for revealing mechanisms underlying neurodegenerative diseases like Parkinson's, where lipid alterations are observed.
• What they did: Lipidomic profiling of C. elegans showed that α-synuclein decreases TAG content, alters lipid droplet and mitochondrial structure, and increases long-chain unsaturated fatty acids; genetic and dietary interventions modulate toxicity.
• The result: These findings suggest that TAG remodeling contributes to α-synuclein toxicity and that medium-chain triglyceride supplementation may serve as a therapeutic strategy for age-related synucleinopathies.
