Leukotrienes are recognized as important mediators of the inflammatory process. Recently, increasing attention has been paid to the role of noninflammatory cells in the regulation of the inflammatory process. To further increase our knowledge of this matter we have, in

Allergic asthma is characterized by reversible airway obstruction and bronchial hyperresponsiveness associated with T(H)2 cell-mediated inflammation. Cysteinyl leukotrienes (CysLTs) are potent lipid mediators involved in bronchoconstriction, mucus secretion, and cell trafficking in asthmatic patients. Recent data have implicated CysLTs in

Both leukotriene D(4) (LTD(4)) and methacholine bronchial provocation tests are measurements of airway responsiveness; however, their correlation and distinction remain unexplored. We sought to compare the 2 tests and classify leukotriene-responsiveness subtypes in asthmatic patients. In this randomized cross-over study
Barbro Dahlén et al.
European journal of clinical pharmacology, 68(10), 1375-1383 (2012-03-30)
Leukotriene D(4) (LTD(4)) is a central mediator in asthma inducing bronchoconstriction and profound disturbances in pulmonary gas exchange in asthmatic subjects. The aim of the study was to compare, for the first time, the influence of the bronchodilators salbutamol (400 μg)
Nathan C Ni et al.
The Journal of pharmacology and experimental therapeutics, 339(3), 768-778 (2011-09-10)
Cysteinyl leukotrienes (CysLTs) are potent inflammatory mediators that predominantly exert their effects by binding to cysteinyl leukotriene receptors of the G protein-coupled receptor family. CysLT receptor 2 (CysLT(2)R), expressed in endothelial cells of some vascular beds, has been implicated in
