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. In allergic rhinitis, CysLTs are released from the nasal mucosa after allergen exposure during both early- and late-phase reactions and are associated with symptoms of allergic rhinitis. cost dapsone venezuela
