NADPH oxidase activation in neutrophils: Role of the phosphorylation of its subunits
Abstract
Neutrophils are key cells of innate immunity and during inflammation. Upon activation, they produce large amounts of superoxide anion (O 2−.) and ensuing reactive oxygen species (ROS) to kill phagocytized microbes. The enzyme responsible for O 2−. production is called the phagocyte NADPH oxidase. This is a multicomponent enzyme system that becomes active after assembly of four cytosolic proteins (p47 phox, p67 phox, p40 phox and Rac2) with the transmembrane proteins (p22 phox and gp91 phox, which form the cytochrome b558). gp91 phox represents the catalytic subunit of the NADPH oxidase and is also called NOX 2. NADPH oxidase‐derived ROS are essential for microbial killing and innate immunity; however, excessive ROS production induces tissue injury and prolonged inflammatory reactions that contribute to inflammatory diseases. Thus, NADPH oxidase activation must be tightly regulated in time and space to limit ROS production. NADPH oxidase activation is regulated by several processes such as phosphorylation of its components, exchange of GDP/GTP on Rac2 and binding of p47 phox and p40 phox to phospholipids. This review aims to provide new insights into the role of the phosphorylation of the NADPH oxidase components, that is gp91 phox, p22 phox, p47 phox, p67 phox and p40 phox, in the activation of this enzyme.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
