In individuals with Down syndrome, neutrophil apoptosis increases and Cu, Zn-SOD is overexpressed.[38] Exogenous H 2 O 2 together with SOD, increase the number of apoptotic neutrophils.[39] SOD may serve as an inhibitory agent of neutrophil-mediated inflammation and may stand for a novel therapeutic approach for the ROS-dependent tissue damage induced by neutrophils through several mechanisms.[2] Preclinical studies with bovine Cu, Zn-SOD showed encouraging results for its use as a human therapeutic agent in acute and chronic inflammatory conditions, including dermatosis due to burn and wound injury.[40,41] Extracellular SOD, Mn-SOD and Cu, Zn-SOD have been described as potential inhibitor of inflammation by various reporters.[42-44] SOD and CF CF is characterized by the chronic inflammation and the recruitment of activated neutrophils.[45] In the plasma of patients with CF, SOD activity was significantly lower as compared with the healthy individuals.[46] Furthermore, in mononuclear, polymorphonuclear, and red cells of CF patients, reduced Cu, Zn-SOD activity was observed.[47] It has been found that the antifibrotic action of Cu, Zn-SOD is mediated by TGF-1 repression followed by phenotypic reversion of myofibroblasts.[48] Radiation-induced fibrosis of breast was significantly reduced by Cu, Zn-SOD.[49] Proapoptotic agents induced apoptosis in CF but not in control cells that were reduced by treatment with SOD mimetic.[50] These findings indicate new therapeutic possibilities targeting antioxidant pathways including SOD, so that oxidative stress and apoptosis can be reduced in CF cells, and proinflammatory response can be limited

PRRs can also sense cell injury-associated endogenous molecules referred to as damage-associated molecular patterns (DAMPs), such as ATP, mitochondrial DNA, hyaluronan, heat shock proteins, and fibrinogen [1, 8]
