Zusammenfassung:Respiratory burst is due to the activation of a membrane bound NADPH oxidase induced by perturbation of the plasma membrane during phagocytosis or following interaction between the cell surface and a number of environmental stimuli. It refers to the increase in the non-mitochondrial O 2 consumption with a concomitant production of different reactive species (superoxide anion, hydrogen peroxide, hydroxyl radical, singlet oxygen ...). The effects of the respiratory burst depend on the intensity and combination of the different actions which are defensive, toxic, activatory and modulatory of the inflammatory process. La “combustion respiratoire” (respiratory burst) est le résultat de l'activation de la NADPH oxydase sous l'effet de la phagocytose ou de l'interaction entre différents stimulus et la surface membranaire de granulocytes et de macrophages. Elle se traduit par une augmentation de la consommation non mitochondriale d'oxygène et la formation d'espèces réactives (anion superoxyde, peroxyde d'hydrogène, radical hydroxyl, atome d'oxygène entre autres). L'incidence de ce phénomène présente différents aspects défensif, toxique, activateur et modulateur de la réponse inflammatoire.
