Leukotrienes belong to the group eicosanoids. They are significant lipid mediators of the arachidonic acid cascade converted by 5-lipoxigenase. Their predominant member is leukotriene B4 (LTB4), which elicits adhesion, chemotaxis, and aggregation of leukocytes. The characteristic chemoattractant effect of LTB4 is induced via G-protein-linked seven-transmembrane spanning leukotriene receptors, which are highly expressed in inflammation and allergy.
