The enzyme responsible for O2???- production is called the NADPH oxidase or respiratory burst oxidase. This multicomponent enzyme system is composed of two transmembrane proteins (p22phox and gp91phox, also called NOX2, which together form the cytochrome b558) and four cytosolic proteins (p47phox, p67phox, p40phox and a GTPase Rac1 or Rac2), which assemble at membrane sites upon cell activation.

The increased ROS production by MDSC is mediated by up-regulated activity of NADPH oxidase (NOX2).
STAT3 upregulates expression of NOX2 subunits, primarily p47(NCF1) and gp91(CYBB) in MDSC,
