Outline of Final Research Achievements |
We established LC-MS/MS-based lipidomics system to monitor more than 500 of fatty acid metabolites simultaneously. From EPA-lipidomics, we identified potent anti-inflammatory metabolites, namely 17,18-diHEPE and 12-OH-17,18-EpETE, that belong to unique omega-3 PUFA metabolic pathway. By using omega-3 desaturase (fat-1) transgenic mouse, we identified cardioprotective function of macrophage-derived EPA metabolite 18-HEPE. Also we found dysregulated synthesis of omega-3 PUFA-derived anti-inflammatory mediator protectin D1 in eosinophils from patients with severe asthma.
