Abstract
Human alveolar macrophages obtained by bronchoalveolar lavage were labeled overnight with [3H]arachidonic acid. The cells were stimulated with calcium ionophore A23187, and the 20:4 oxygenated metabolites released into the culture medium were identified by reverse-phase HPLC. Leukotriene B4 was the major 20:4 metabolite produced by these cultures. Leukotriene B4 was identified by its reverse-phase HPLC elution time, its UV spectrum, and its chemotactic and chemokinetic activities for neutrophils. In addition, the macrophage- and neutrophil-derived leukotriene B4 free acids and methyl esters were found to have identical HPLC retention times.Entities:
