Reactive oxygen species neutrophils
WebWhen neutrophils arrive at the site of invasion, they bind to invading bacteria and ingest them by phagocytosis, a process mediated by a metabolic pathway called a respiratory burst, which generates oxidative species such as H 2 O 2 and hypochlorous acid HOCl [ 58 ]. WebNeutrophils are both effectors of host defense and central arbitrators of lung injury ( 6 ). Neutrophils kill microorganisms, using both reactive oxygen species (ROS) and granule-associated proteases ( 7, 8 ). ROS production in neutrophils is largely dependent on the nicotinamide adenine dinucleotide phosphate reduced (NADPH) oxidase system ( 9 ).
