Nitroxide Tempol down-regulates kinase activities associated with NADPH oxidase function in phagocytic cells and potentially decreases their fungicidal response
Aims The identification of novel targets to control inflammation in humans is probably the primary challenge that impairs the development of new anti-inflammatory drugs. Therefore, the modulation of intracellular signaling pathways in phagocytes may be an interesting means of achieving this goal. However, this change to signaling can compromise the host’s susceptibility to invading pathogens. We investigated whether the antioxidant nitroxide Tempol regulates the activity of kinases associated with the production of oxidants in neutrophils, which affects the fungicidal capability of these cells. Main methods The effects of Tempol on PMA- or fMLP-activated neutrophils were examined by oxygen consumption as an index of the oxidative burst, a release of extracellular and total Reactive Oxygen Species (ROS) by chemiluminescence, kinase activities through analysis of ATP consumption during enzyme activities and the dot blot immunoassay and, finally, by neutrophil capacity of killing Candida albicans. Key findings Tempol significantly inhibited the neutrophil oxidative burst in a concentration-dependent manner and decreased oxygen consumption (IC50 = 45 muM) and extracellular/total ROS formation with an increase on the lag period response. In addition, Tempol inhibited neutrophil kinase activities (i.e., a decrease in protein phosphorylation) elicited through different biochemical pathways and consequently impaired the fungicidal activity of these cells. Significance Although Tempol has potential anti-inflammatory activity that acts on different intracellular pathways (such as those involving kinases), researchers should be cautious, since this nitroxide down-regulated oxidants production and the fungicidal response of neutrophils.
