title: Characterization and expression of NADPH oxidase in LPS-, poly(I:C)- and zymosan-stimulated trout (Oncorhynchus mykiss W.) macrophages.
abstract: In vertebrates, the generation of superoxide reactive oxygen species (ROS) via activation of the Nox/Duox family of NADPH oxidases is a prototypical feature of the pathogen-induced defensive responses of activated professional phagocytes. To understand the role of the rainbow trout (Oncorhynchus mykiss) Phox oxidase from a phylogenetic and functional perspective we describe the cloning, sequencing and expression analysis of multiple NADPH components in cultured macrophages. Phylogenetic analyses support the notion of the emergence of Phox-related components before the diversification of basal euteleosts and add to the limited collection of teleost NADPH oxidases. Expression studies using lipopolysaccharide, polyinosine-polycytidylic acid and zymosan to mimic the onset of inflammatory responses in trout macrophages suggest differences in regulation of the NADPH complex throughout the maturation/differentiation period of culture and between different treatments.
