title: The use of diphenylene iodonium, an inhibitor of NADPH oxidase, to investigate the antimicrobial action of human monocyte derived macrophages.
abstract: Diphenylene iodonium is an inhibitor of the respiratory burst-generating NADPH oxidase of phagocytes. The effect of this compound on human monocyte-derived macrophages and its usefulness in exploring the antimicrobial mechanisms of phagocytes was examined. 1 microM diphenylene iodonium inhibited hydrogen peroxide production by human macrophages and the activity of these cells against Toxoplasma gondii. At this concentration macrophage degranulation was unaffected.
