Lipoxin

Lipoxins are the most recent addition to the family of bioactive products generated from Arachidonic Acid (AA). They have a number of proinflammatory and anti-inflammatory actions. Lipoxins are short lived endogenously produced nonclassic eicosanoids whose appearance in inflammation signals the resolution of inflammation. They are abbreviated as LX, an acronym for lipoxygenase (LO) interaction products. At present two lipoxins have been identified; lipoxin A₄ (LXA₄) and lipoxin B₄ (LXB₄).
