      Leukotriene B4

      Leukotriene B4 (5S,12R-dihydroxy-6Z,8E,10E,14Z-eicosatetraenoic acid) is a pro-inflammatory eicosanoid mediator synthesised in myeloid cells from arachidonic acid. Synthesis is catalysed by 5-lipoxygenase and leukotriene A4 hydrolase and is increased by inflammatory mediators including endotoxin, complement fragments, tumor necrosis factor and interleukins. Leukotriene B4 is able to induce the adhesion and activation of leukocytes on the endothelium, allowing them to bind to and cross it into the tissue. In neutrophils, it is also a potent chemoattractant, and is able to induce the formation of reactive oxygen species and the release of lysosomal enzymes by these cells.
