The cysteinyl leukotrienes LTC 4, LTD 4, LTE 4 are products of arachidonic acid metabolism and are released from various cells, including mast cells and eosinophils. These eicosanoids bind to cysteinyl leukotriene CysLT receptors. The CysLT type-1 CysLT 1 receptor is found in the human airway including airway smooth muscle cells and airway macrophages and on other pro-inflammatory cells including eosinophils and certain myeloid stem cells. CysLTs have been correlated with the pathophysiology of asthma and allergic rhinitis. In asthma, leukotriene-mediated effects include airway edema, smooth muscle contraction, and altered cellular activity associated with the inflammatory process.
