From: The role of neutrophils during intestinal inflammation

Biosynthetic pathways of pro- and anti-inflammatory mediators derived from polyunsaturated fatty acids involving 5-lipoxygenase (LO) from neutrophils. FLAP, 5-lipoxygenase-activating protein; H(P)-DHA, hydroxyperoxy docosahexanoic acid; H(P)-EPE, hydroxyperoxy eicosapentanoic acid; H(P)-ETE, hydroxyperoxy eicosatetraenoic acid; LTA4, leukotriene A4; PMN, polymorphonuclear leukocytes.
