Clinical studies of asthma phenotypes focusing on the role of the leukotrienes. Author: Gyllfors, Per. Date: 2006-12-15 Key words: asthma, leukotriene, leukotriene antagonist, 5-lipoxygenase. INTRODUCTION There is increasing evidence for the role played by the cysteinyl leukotrienes LTC4, LTD4 and LTE4 in the pathogenesis of bronchial asthma. Evidence is also accumulating that pharma-cological manipulation through antagonism or inhibition of The role of leukotrienes in asthma.

Leukotrienes have a number of effects that lead to the production of asthma symptoms. First, they promote bronchiole constriction leading to narrowing of the airways. The leukotrienes play a definitive role as mediators in bronchial asthma, as they present at serum levels consistent with the severity of acute asthma, and decreased with the improvement of the disease. The beneficial effects of corticosteroid in asthmatic patients appear to be mediated by mechanisms other than reduction of leukotrienes.

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. The cysteinyl leukotrienes (CysLT), LTC 4, LTD 4, and LTE 4, have been shown to be essential mediators in asthma, making them obvious targets for therapy. These cysteinyl leukotrienes, previously known as the slow‐reacting substance of anaphylaxis (SRS‐A), mediate many of the features of asthma, including bronchial constriction, bronchial hyperreactivity, edema, and eosinophilia.

Researchers have noted that atherosclerotic vascular lesions express the entire biochemical machinery necessary for leukotriene production, including 5-lipooxygenase, FLAP, and other distal enzymes important for leukotriene synthesis.

At least two receptor subtypes for CysLTs – CysLT1 and CysLT2 – have been identified. Most of the pathophysiological effects of CysLTs in asthma, including increased airway smooth muscle activity, microvascular permeability and airway mucus Later it has been shown that leukotrienes play a central pathophysiological role in asthma mediating bronchoconstriction, mucus secretion, oedema and inflammation through activation of several Leukotrienes are thought to contribute to the pathophysiology of asthma. Leukotrienes are synthesised from arachidonic acid by a specific synthesis pathway whose key enzyme is 5-lipoxygenase. Cysteinyl leukotrienes (leukotrienes C4, D4 and E4) have been shown to mimic all the pathologic changes that are characteristic of asthma, whereas leukotriene B4 does not appear to exert biological properties relevant to asthma. Role of Leukotrienes in Exercise-induced Asthma: Inhibitory Effect of ICI 204219, a Potent Leukotriene D 4 Receptor Antagonist Leukotrienes (LTs), including cysteinyl LTs (CysLTs) and LTB 4, are potent lipid mediators that are pivotal in the pathophysiology of asthma phenotypes.At least two receptor subtypes for CysLTs – CysLT 1 and CysLT 2 – have been identified. 2021-03-31 · SUMMARY: Leukotrienes are clearly involved in airway inflammation and certain clinical features of asthma.
