WebMar 1, 1999 · This study indicates that theactivation of NF-kappaB following IL-1beta treatment involves the activation of phospholipase A2 and 5-LOX and the production of reactive oxygen intermediates (ROIs) in lymphoid cells, while in epithelial cells, another pathway predominates and could involve the acid sphingomyelinase. 134 PDF WebEarly production of reactive oxygen intermediates (ROI) is a hallmark of the plant defense response. Many studies document the detection of O 2 and or its dismutation product, H O , during incompatible interactions between resistant plants and avirulent pathogens (1–4). During the defense response, ROI can inhibit the
