\u2666 Oxidative stress and its modulation by antioxidant compounds and their metabolites<\/span><\/span><\/p>\n

The research group of the Unit of Experimental Pathology, coordinated by Dr. Deiana, focuses mainly on oxidative stress and related diseases, and its modulation by antioxidant compounds and their metabolites. Suggestions that oxidative stress plays a role in human diseases have led to the proposal that health might be improved by increased dietary intake of antioxidants. Mediterranean\u2013style diet is rich in plant-derived antioxidants, such as phenolic compounds and thiols. In the last years, the research group has evaluated the biopotency of dietary antioxidant factors, using various experimental models, from the simplest in vitro<\/i> systems to the more complex studies on cell cultures and in vivo<\/i> models. Currently major interest is centered on the toxicity of lipid oxidation products in relation to the inflammatory process and cell death that characterize inflammatory bowel diseases and atherosclerosis, and the modulatory activity of antioxidant compounds. The protective role of antioxidants and their metabolites is investigated as capacity of counteracting the oxidative damage, working as direct antioxidants, that scavenge excessive damaging free radicals, and as capacity to modulate cellular redox status, through the interaction with intracellular signaling cascades involved in the cellular response to oxidative injury.<\/span><\/p>\n
