Additionally, leukotrienes have been shown to call white blood cells to lung tissue, potentially contributing to the swelling of the lung’s lining. Acute asthma attacks are often triggered by allergens or exercise. 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.

Infiltration of It has been almost 25 years since the elucidation of the structure of SRS-A as a mixture of the cysteinyl leukotrienes (LT) and just over 5 years since agents that act on leukotriene pathway have been available as asthma treatments [4, 5]. In contrast, studies of biopsies and BAL from individuals with asthma have most often demonstrated enhanced production of Th2 cytokines including IL-4, IL-5, and IL-13 (2–4). In keeping with the importance of IgE and eosinophils, asthma is now looked at as a disease that is characterized by Th2 cell and Th2 cytokine excess (4, 5). Leukotriene inhibitors are the first new class of medications for the treatment of persistent asthma that have been approved by the U.S. Food and Drug Administration in more than two decades.

Leukotrienes play a key role in asthma in three ways: causing inflammation, bronchoconstriction and mucus production. The cysteinyl leukotrienes (LTC 4 , LTD 4 and LTE 4 ) have been shown to be the most potent bronchconstrictors in humans and are believed to play a crucial role in asthmatic airway obstruction. Leukotrienes (LTs), including LTB (4) and cysteinyl-LTs (CysLTs) (LTC (4), LTD (4), and LTE (4)), are potent inflammatory lipid mediators which are derived from 5-lipoxygenase activity.
