Stimulation by lipoxygenase products of superoxide anion production in FMLP-treated neutrophils

J K Beckman et al. Lipids. 1985 May.

Abstract

Our recent observation that leukotriene B4 (10(-9)M) is a potent enhancer of FMLP-initiated neutrophil superoxide anion formation prompted an evaluation of the ability of other lipoxygenase products and related compounds to modulate this response. The results indicate that FMLP-evoked O-2 may be enhanced by 10(-8)-10(-7)M levels of a number of lipids, in addition to LTB4, including 5-HPETE, 5-HETE, 5,15-DiHPETE and by higher levels of other 15-series lipoxygenase products and arachidonic acid. It is of interest that the relative potency of these agents in potentiating the superoxide response to FMLP approximately parallels their reported ability to induce chemotactic activity in leukocytes.
