A burst of plant NADPH oxidases
Trends in Plant Science, 2012Reactive oxygen species (ROS) are highly reactive molecules able to damage cellular components but they also act as cell signalling elements. ROS are produced by many different enzymatic systems. Plant NADPH oxidases, also known as respiratory burst oxidase homologues (RBOHs), are the most thoroughly studied enzymatic ROS-generating systems and our ...

NADPH oxidases in cardiovascular disease
Free Radical Biology and Medicine, 2010Reactive oxygen species (ROS) contribute to several aspects of vascular diseases including ischemia-reperfusion injury, scavenging of nitric oxide, or stimulation of inflammation and hypertrophy. NADPH oxidases of the Nox family are differentially expressed in the cardiovascular system, induced or activated by cardiovascular risk factors and ...

NADPH oxidases and cardiac remodelling
Heart Failure Reviews, 2010A heart under chronic stress undergoes cardiac remodelling, a process that comprises structural and functional changes including cardiomyocyte hypertrophy, interstitial fibrosis, contractile dysfunction, cell death and ventricular dilatation. Reactive oxygen species (ROS)-dependent modulation of intracellular signalling is implicated in the development

NADPH oxidase and heart failure
Current Opinion in Pharmacology, 2006Reactive oxygen species play important roles in the pathophysiology of chronic heart failure secondary to chronic left ventricular hypertrophy or myocardial infarction. Reactive oxygen species influence several components of the phenotype of the failing heart, including contractile function, interstitial fibrosis, endothelial dysfunction and myocyte ...

The NADPH Oxidase Family and Its Inhibitors
Antioxidants & Redox Signaling, 2020Significance: The oxidative stress, resulting from an imbalance in the production and scavenging of reactive oxygen species (ROS), is known to be involved in the development and progression of several pathologies. The excess of ROS production is often due to an overactivation of nicotinamide adenine dinucleotide phosphate (NADPH) oxidases (NOX) and for

NADPH oxidase and the respiratory burst
Seminars in Cell Biology, 1995Phagocytic cells possess an electron-transport system which accepts electrons from NADPH in the cytosol to reduce oxygen to the superoxide radical in the vacuolar lumen. The superoxide is instrumental in killing ingested microorganisms. Patients suffering from chronic granulomatous disease (CGD), in which this system is failing, are abnormally ...

Assembly of the phagocyte NADPH oxidase
Histochemistry and Cell Biology, 2004Stimulated phagocytes undergo a burst in respiration whereby molecular oxygen is converted to superoxide anion through the action of an NADPH-dependent oxidase. The multicomponent phagocyte oxidase is unassembled and inactive in resting cells but assembles at the plasma or phagosomal membrane upon phagocyte activation.

The NADPH‐Dependent Oxidase of Phagocytes
Proceedings of the Association of American Physicians, 1999Polymorphonuclear leukocytes (PMNs) represent a prominent cellular element in the innate immune system, serving to ingest exogenous particles and microbes and to kill phagocytosed microorganisms. The microbicidal activity of PMNs depends on the interactions of a broad array of potent systems, including relatively stable degradative proteins as well as ...
