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 …

The blood-brain barrier (BBB) is a critical interface between the systemic circulation and the brain. It is a specialized multicellular unit composed of brain microvascular endothelial cells (BMECs), pericytes, a basement membrane, and astrocytic end foot processes. BMECs are a principal component of the BBB that provide the structural framework needed for the stringent transport of molecules into the brain. BMEC dysfunction permits the trafficking of neurotoxins from systemic circulation into the brain, which ultimately exacerbates BBB dysfunction and neuroinflammation. Studies have shown that BBB dysfunction is a key determinant of cognitive decline in sepsis. However, there are critical knowledge …

Sepsis is a disorder that targets the microcirculation with significant effects at blood-tissue barriers such as the blood-brain barrier (BBB) and gut-vascular barrier (GVB). Intestinal barrier dysfunction is thought to be one of the most important contributors to multi-organ dysfunction in sepsis. As a common site of infection, the impaired gut allows the dissemination of bacteria, which exacerbates the disease pathophysiology, and can lead to long-term morbidity and mortality. The mechanisms that influence altered barrier permeability in the GVB in sepsis and other inflammatory disorders are not well understood. Tissue-nonspecific alkaline phosphatase (TNAP) enzyme activity, which has been shown to …
