NADPH oxidases in cardiovascular health and disease.
Increased oxidative stress plays an important role in the pathophysiology of cardiovascular diseases such as hypertension, atherosclerosis, diabetes, cardiac hypertrophy, heart failure, and ischemia-reperfusion. Although several sources of reactive oxygen species (ROS) may be involved, a family of NADPH oxidases appears to be especially important for redox signaling and may be amenable to speci...
متن کاملActivation of antibacterial autophagy by NADPH oxidases.
Autophagy plays an important role in immunity to microbial pathogens. The autophagy system can target bacteria in phagosomes, promoting phagosome maturation and preventing pathogen escape into the cytosol. Recently, Toll-like receptor (TLR) signaling from phagosomes was found to initiate their targeting by the autophagy system, but the mechanism by which TLR signaling activates autophagy is unc...
متن کاملNADPH oxidases of the brain: distribution, regulation, and function.
The NADPH oxidase is a multi-subunit enzyme that catalyzes the reduction of molecular oxygen to form superoxide (O(2)(-)). While classically linked to the respiratory burst in neutrophils, recent evidence now shows that O(2)(-) (and associated reactive oxygen species, ROS) generated by NADPH oxidase in nonphagocytic cells serves myriad functions in health and disease. An entire new family of NA...

and Duox in the respiratory epithelium. The location of these ROS-generating enzymes in the barrier tissues has prompted the expectation of their participation in host defense against invading pathogens in these tissues. Indeed, recent studies have begun to support this expectation, demonstrating roles in bacterial killing, cytokine production, apoptosis, gene expression and signaling, includin...
متن کاملElectron and proton transport by NADPH oxidases.
The NADPH oxidase is the main weapon of phagocytic white blood cells that are the first line of defence of our body against invading pathogens, and patients lacking a functional oxidase suffer from severe and recurrent infections. The oxidase is a multisubunit enzyme complex that transports electrons from cytoplasmic NADPH to molecular oxygen in order to generate superoxide free radicals. Elect...
