Witryna1 cze 2024 · Abstract. The reactive oxygen species (ROS)-producing enzyme NADPH oxidase (NOX) was first identified in the membrane of phagocytic cells. For many … Witryna18 wrz 2015 · Within the Nox family, the NADPH oxidase Nox4 has a unique position as it is constitutively active and produces H 2 O 2 rather than O 2 − . Nox4 is therefore incapable of scavenging NO and its low constitutive H 2 O 2 production might even be beneficial. We hypothesized that Nox4 acts as an endogenous anti-atherosclerotic …
