Cysteinyl-leukotriene 1 receptor antagonist attenuates bleomycin-induced pulmonary fibrosis in mice

Leukotrienes are lipid mediators of inflammation derived from the 5-lipoxygenase pathway of arachidonic acid metabolism, and recent evidence suggests that they play an important role in pulmonary fibrosis. Montelukast is a cysteinyl-leukotriene 1 receptor antagonist that has been found to reduce airway remodeling, including subepithelial fibrosis, in a murine model of asthma, but the therapeutic effect of montelukast on pulmonary fibrosis...
