摘要
In addition to their role in bacterial killing by leukocytes, reactive oxygen species (ROS) have been increasingly recognized as important components of signaling and host defense in other cell types. The formation of ROS in both phagocytic- and non-phagocytic cells involves membrane-localized NADPH oxidases (Noxs). Nox proteins show structural homology to the cytochrome b(558) of leukocytes but, until recently, their regulation has been poorly understood. Here, we describe our current understanding of Nox function, and discuss emerging paradigms for regulation of Nox activity by Rac GTPase and/or other cytosolic components.
