Lipoxin
Lipoxins are members of the family of bioactive products generated from Arachidonic Acid (AA). They have a number of immunomodulatory 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).
