Ergothioneine (EGT) is an antioxidant and potential anti-inflammatory molecule that may have protective effects against the lipid-induced oxidative stress and inflammation that occurs in the vasculature of individuals with obesity and metabolic syndrome. This thesis addresses the hypothesis that EGT supplementation decreases endothelial cell dysfunction and macrophage inflammatory characteristics under high lipid conditions, and markers of atherosclerotic risk in diet-induced obese mice. Results showed that EGT did not influence endothelial tube formation or stability but reduced nitric oxide production in endothelial cells. Moreover, EGT decreased the production of reactive oxygen species, and potentially nitric oxide, by macrophages. In diet-induced obese …
