Abstract
The NADPH oxidase NOX2 complex consists of assembled cytosolic and redox membrane proteins. In mammalian cells, natural arachidonic acid (cis-AA), released by activated phospholipase-A2, plays an important role in the activation of the NADPH oxidase, but the mechanism of action of cis-AA is still a matter of debate. In cell-free systems, cis-AA is commonly used for activation although its structural effects are still unclear. Undoubtedly cis-AA participates in the synergistic multi-partner assembly that can be hardly studied at the molecular level in vivo due to cellular complexity. The capacity of this anionic amphiphilic fatty acid to activate the oxidase is mainly explained by its ability to disrupt intramolecular bonds, mimicking phosphorylation events in cell signaling and therefore allowing protein-protein interactions. Interestingly the geometric isomerism of the fatty acid and its purity are crucial for optimal superoxide production in cell-free assays. Indeed, optimal NADPH oxidase assembly was hampered by the substitution of the cis form by the trans forms of AA isomers (Souabni et al., BBA-Biomembranes 1818:2314-2324, 2012). Structural analysis of the changes induced by these two compounds, by circular dichroism and by biochemical methods, revealed differences in the interaction between subunits. We describe how the specific geometry of AA plays an important role in the activation of the NOX2 complex.

Abstract
The action of Cr-LAAO, an l-amino acid oxidase isolated from Calloselasma rhodosthoma snake venom, on NADPH oxidase activation in isolated human neutrophil function was investigated. This enzyme has an intrinsic activity of hydrogen peroxide production. Cr-LAAO, in its native form, induces the ROS production in neutrophil and migration of cytosolic NADPH oxidase components p40phox, p47phox and p67phox to the membrane, and Rac, a GTPase protein member, with the involvement of intracellular signaling mediated by phospho PKC-α. In its inactive form, iCr-LAAO does not induce NADPH oxidase activation in neutrophil showing that the intrinsic enzymatic activity does not have a role in this process, suggesting that its primary structure is essential for the cell's stimulation. Accordingly, the data showed for the first time that the Cr-LAAO has a role in NADPH oxidase complex activation triggering relevant proinflammatory events in human neutrophils.

Abstract
During the phagocytosis of pathogens by phagocyte cells, the NADPH oxidase complex is activated to produce superoxide anion, a precursor of microbial oxidants. The activated NADPH oxidase complex from phagocytes consists in two transmembrane proteins (Nox2 and p22phox) and four cytosolic proteins (p40phox, p47phox, p67phox and Rac1-2). In the resting state of the cells, these proteins are dispersed in the cytosol, the membrane of granules and the plasma membrane. In order to synchronize the assembly of the cytosolic subunits on the membrane components of the oxidase, a fusion of the cytosolic proteins p47phox, p67phox and Rac1 named trimera was constructed. The trimera investigated in this paper is composed of the p47phox segment 1-286, the p67phox segment 1-212 and the mutated Rac1(Q61L). We demonstrate that the complex trimera-cyt b558 is functionally comparable to the one containing the separated subunits. Each of the subunits p47phox, p67phox and Rac1Q61L has kept its own activating property. The trimera is produced in an activated conformation as seen by circular dichroism. However, the presence of amphiphile is still necessary in a cell-free system to trigger superoxide anion production. The COS7gp91-p22 cells expressing the trimera produce continuously superoxide anion at high rate. This constitutive activity in cells can be of particular interest for understanding the NADPH oxidase functioning independently of signaling pathways.

Abstract
Chronic granulomatous disease (CGD) is a rare inherited immunodeficiency due to dysfunction of the phagocytic nicotinamide adenine dinucleotide phosphate (NADPH) oxidase complex leading to severe and recurrent infections in early childhood. The main genetic form is the X-linked CGD leading to the absence of cytochrome b558 composed of NOX2 and p22phox, the membrane partners of the NADPH oxidase complex. The first cause of death of CGD patients is pulmonary infections. Recombinant proteoliposome-based therapy is an emerging and innovative approach for membrane protein delivery, which could be an alternative local, targeted treatment to fight lung infections in CGD patients. We developed an enzyme therapy using recombinant NOX2/p22phox liposomes to supply the NADPH oxidase activity in X0-linked CGD (X0-CGD) macrophages. Using an optimized prokaryotic cell-free protein synthesis system, a recombinant cytochrome b558 containing functional hemes was produced and directly inserted into the lipid bilayer of specific liposomes. The size of the NOX2/p22phox liposomes was estimated to be around 700 nm. These proteoliposomes were able to generate reactive oxygen species (ROS) in an activated reconstituted cell-free NADPH oxidase activation assay in the presence of recombinant p47phox, p67phox and Rac, the cytosolic components of the NADPH oxidase complex. Furthermore, using flow cytometry and fluorescence microscopy, we demonstrated that cytochrome b558 was successfully delivered to the plasma membrane of X0-CGD-induced pluripotent stem cell (iPSC)-derived macrophages. In addition, NADPH oxidase activity was restored in X0-CGD iPSC-derived macrophages treated with NOX2/p22phox liposomes for 8 h without any toxicity. In conclusion, we confirmed that proteoliposomes provide a new promising technology for the delivery of functional proteins to the membrane of targeted cells. This efficient liposomal enzyme replacement therapy will be useful for future treatment of pulmonary infections in CGD patients refractory to conventional anti-infectious treatments.

Abstract
Activation of phagocyte cells from an innate immune system is associated with a massive consumption of molecular oxygen to generate highly reactive oxygen species (ROS) as microbial weapons. This is achieved by a multiprotein complex, the so-called NADPH oxidase. The activity of phagocyte NADPH oxidase relies on an assembly of more than five proteins, among them the membrane heterodimer named flavocytochrome b 558 (Cytb 558), constituted by the tight association of the gp91phox (also named Nox2) and p22phox proteins. The Cytb 558 is the membrane catalytic core of the NADPH oxidase complex, through which the reducing equivalent provided by NADPH is transferred via the associated prosthetic groups (one flavin and two hemes) to reduce dioxygen into superoxide anion. The other major proteins (p47phox, p67phox, p40phox, Rac) requisite for the complex activity are cytosolic proteins. Thus, the NADPH oxidase functioning relies on a synergic multi-partner assembly that in vivo can be hardly studied at the molecular level due to the cell complexity. Thus, a cell-free assay method has been developed to study the NADPH oxidase activity that allows measuring and eventually quantifying the ROS generation based on optical techniques following reduction of cytochrome c. This setup is a valuable tool for the identification of protein interactions, of crucial components and additives for a functional enzyme. Recently, this method was improved by the engineering and the production of a complete recombinant NADPH oxidase complex using the combination of purified proteins expressed in bacterial and yeast host cells. The reconstitution into artificial membrane leads to a fully controllable system that permits fine functional studies.

Abstract
The NADPH-oxidase complex, which plays beneficial or detrimental role in the inflammatory and degenerative diseases, is a membrane multi-subunit complex tightly regulated in order to produce superoxide anions, precursor of oxygen reactive species (ROS), in cells. The flavocytochrome b(558) (Cytb(558)) is the catalytic core of the NADPH oxidase which consists of two membrane proteins gp91(phox) (highly glycosylated) and p22(phox). In this work we took advantage of heterologous yeast cells engineered to express wild-type bovine Cytb(558) to analyze the properties of the NADPH oxidase activity during the biosynthesis processing steps of gp91(phox) and p22(phox) within endoplasmic reticulum (ER) and plasma membrane (Pmb). Our data showed that, in yeast, the heterodimerization at the endoplasmic reticulum membranes was concomitant with high level glycosylation of gp91(phox) and the heme acquisition. This study also demonstrated that the phagocyte NADPH oxidase was active at ER membranes and that this activity was surprisingly higher at the ER compared to the Pmb membranes. We have correlated these findings with the presence of sterols in the plasma membranes and their absence in ER membranes. This correlation was confirmed by decreased superoxide anion production rates in proteoliposomes supplemented with ergosterol or cholesterol. Our data support the idea that membrane environment might be determinant for ROS regulation and that sterols could directly interact with the membrane proteins of the NADPH oxidase constraining its capacity to produce superoxide anions.
