Cysteinyl Leukotrienes and Their Receptors: Molecular and Functional Characteristics

Cysteinyl leukotrienes and their receptors: molecular and functional characteristics.

The cysteinyl leukotrienes (CysLTs) are a family of potent inflammatory lipid mediators synthesized from arachidonic acid by a variety of cells including mast cells, eosinophils, basophils and macrophages. The family includes leukotriene C(4) (LTC(4)), leukotriene D(4) (LTD(4)) and leukotriene E(4) (LTE(4)), which are potent biological mediators in the pathophysiology of inflammatory diseases a...

Cysteinyl Leukotrienes and Their Receptors; Emerging Concepts

Cysteinyl leukotrienes (cys-LTs) are potent mediators of inflammation derived from arachidonic acid through the 5-lipoxygenase/leukotriene C4 synthase pathway. The derivation of their chemical structures and identification of their pharmacologic properties predated the cloning of their classical receptors and the development of drugs that modify their synthesis and actions. Recent studies have ...

Immune and Inflammatory Responses Cellular Distribution and Function in Cysteinyl Leukotrienes and Their Receptors:

Studies of receptors and modulatory mechanisms in functional responses to cysteinyl-leukotrienes in smooth muscle.

Cysteinyl-leukotrienes, i.e. leukotriene (LT) C4, D4 and E4, are inflammatory mediators and potent airway- and vasoconstrictors. Two different cysteinyl-leukotriene receptors have been cloned, CysLT1 and CysLT2. This report reviews recent data on CysLT receptor characterisation as well as studies of modulatory mechanisms involved in cysteinyl-leukotriene-induced responses. On the basis of funct...
