and allergic asthma. The main focus was on leukotrienes and other eicosanoids, metabolites of arachidonic acid, and the major experimental approach employed was bronchial challenge. Thirty-three subjects known to be suffering from aspirin-intolerant asthma were challenged with celecoxib a selective inhibitor of COX-2. The recent elucidation of the inflammatory responses underlying asthma and allergic rhinitis has stimulated the development of new anti-asthma treatments, including numerous antileukotriene agents. These agents, which represent a new direction in targeted therapy, either antagonize the leukotriene receptor (e.g. zafirlukast) or block the synthesis of leukotrienes (e.g. zileuton).

Role of leukotrienes asthma

Introduction. Leukotrienes are thought to play a central role in the bronchoconstriction, edema formation, and 2. Leukotriene biosynthesis and receptor-mediated actions. Leukotrienes are potent lipid mediators which have long been 3. Leukotrienes and 1999-07-10 · Inflammatory molecules called leukotrienes are one of several substances which are released by mast cells during an asthma attack, and it is leukotrienes which are primarily responsible for the bronchoconstriction. In chronic, more severe cases of asthma, general bronchial hyperreactivity (or smooth muscle twitchiness) is largely … Leukotrienes (LT), both the cysteinyl LTs, LTC 4, LTD 4 and LTE 4, as well as LTB 4 have been implicated in the clinical course, physiologic changes, and pathogenesis of asthma.
