Return to overview
The metabolism of 5-HETE to 5-Oxo-ETE is catalysed by the enzyme 5-Hydroxyeicosanoid dehydrogenase (5-HEDH). This enzyme acts reversibly and has been reported to be found in eosinophils, monocytes, DC, B-lymphocytes, keratinocytes and platelets (Steinhilber book) *skin (need to check). The product binds with the OXE receptor (Hosoi2002) and is 30-100 more bioactive than 5-HETE. 5-Oxo-ETE is a chemoattractant for neutrophils and eosinophils.
