[Post-receptor formation of active forms of oxygen in nonphagocytic cells].
Generation of reactive oxygen species (ROS) in A431 cells, NIH3T3 fibroblasts expressing normal epidermal growth factor (EGF) receptor, L929 fibroblasts, and in mouse peritoneal macrophages (professionally phagocytic cells) upon the effect of different activators has been studied. It has been shown that ROS formation in A431 and NIH3T3 cells upon the effect of EGF is time- and dose-dependent process. A variety of stimuli were used to stimulate macrophage ROS production. However, the effect of only phorbol ester, opsonized zymozan, peptide fMLP, and platelet activating factor led to ROS generation, whereas tumor necrosis factor alpha, interferon gamma, and lipopolysaccharide did not stimulate macrophage oxidative burst. The literature data on ROS generation in a variety of cell types are presented. ROS formed in cells acted upon certain agents are considered as the molecules participating in intracellular signaling.
