We investigated the interactions of exogenous leukotriene A4 (LTA4) with isolated cells in the presence or absence of cellular stimuli. The majority of isolated cells are able to transform exogenous LTA4 into LTB4 as well as LTC4. In eosinophils, LTA4 induced 15-hydroxy-eicosatetranoic acid formation and was converted into LTB4. The Ca-ionophore-induced generation of LTB4 from polymorphonuclear leukocytes or from the cell fraction containing lymphocytes, monocytes and basophils was significantly suppressed with LTA4 while the formation of LTC4 was increased. Conversely, the Na-fluoride- and fMLP-induced generation of LTB4 was significantly increased. Our results suggest that the stimulus and the cellular composition determine the pattern of the generated inflammatory mediators.
