LTD4 (Leukotriene D4) is a bioactive eicosanoid that plays a central role in the inflammatory response, particularly in the pathophysiology of asthma and allergic reactions. It is a product of the 5-lipoxygenase pathway and acts by binding to cysteinyl leukotriene receptors on target cells. In research, LTD4 (Leukotriene D4) is utilized to study the signaling pathways involved in bronchoconstriction, increased vascular permeability, and eosinophil recruitment. By examining the effects of LTD4 (Leukotriene D4) on various cell types, researchers can elucidate the cellular mechanisms that contribute to inflammation and hypersensitivity reactions. Additionally, LTD4 (Leukotriene D4) serves as a tool to test the efficacy of leukotriene receptor antagonists and to investigate targets for intervention in conditions associated with leukotriene-mediated inflammation.
