Common Name | 15-HEPE |
---|
Description | 15-HEPE has been identified as a possible anti-inflammatory metabolite, and its elevated presence in the epidermis of animals fed oils rich in 20:5(n-3) or 18:3(n-6) may provide a mechanism for the beneficial effects of these oils on inflammatory conditions. 15-HEPE is a metabolite of eicosapentaenoic acid (EPA) which has anti-inflammatory properties and plays an important role in the resolution phase of inflammation. 15-HEPE is deposited in the epidermis, particularly in the metabolically active basal layer. This is considered advantageous in psoriasis therapy. (PMID: 17540633 , 2106017 ). |
