Leukotrienes are major products of 5-lipoxygenase metabolism of arachidonic acid. Leukotriene B4 (LTB4) stimulates leukocyte functions including lysosomal enzyme release, adhesion, and aggregation of polymorphonuclear leukocytes. LTB4 has been implicated as a potent mediator of inflammatory diseases and immunoregulation. The cysteinyl leukotrienes (LTC4, LTD4, and LTE4) are formed by addition of cysteine derivatives to LTA4. The conversion of LTA4 to LTC4 by the enzyme LTC4 synthase limits the rate of cysteinyl leukotriene formation. Cysteinyl leukotrienes are potent lipid mediators in inflammation, inducing smooth muscle contractions and increased capillary permeability.
