Leukotriene B4 is a pro-inflammatory mediator synthesized in myeloid cells from arachidonic acid. Leukotriene B4 induces recruitment and activation of neutrophils, monocytes and eosinophils. It also stimulates the production of a number of proinflammatory cytokines and mediators indicating an ability to augment and prolong tissue inflammation. Elevated levels of leukotriene B4 have been found in a number of inflammatory diseases and levels are related to disease activity in some of these. Leukotriene B4 has a central role in metabolic dysfunctions. By increasing MyD88 expression, leukotriene B4 enhances macrophage response to TLR/IL1 receptor agonists potentiating the sterile inflammation, a central event in metabolic disease progression. Thus, leukotriene B4 is a potential therapeutic target for the treatment of metabolic disorders. Leukotriene B4 could serve as a biomarker for evaluating bestatin efficacy in colorectal cancer.
