Concept of eicosanoids
WebEicosanoids are potent chemical messengers that have well-established roles in regulation of inflammation, immunity, platelet aggregation, smooth muscle contraction and renal function (Nicolaou and Kafatos, 2004). They include prostaglandins, thromboxanes and leukotrienes and are usually produced from the omega-6 fatty acid arachidonic acid. WebEmail [email protected]. Purpose: Lipid mediators, particularly eicosanoids, are associated with airway inflammation, especially with the eosinophilic influx. This study aimed to measure lipid mediators and cells in induced sputum, that could possibly reflect the inflammatory process in the bronchial tree of COPD subjects.
