Recent Patents on Oxidative Stress-Related Biomarkers in Chronic Heart Failure: The Central Role of Endothelium and Myeloperoxidase
2013
Endothelial cells are key modulators of multiple physiological processes, and their impairment may result in the generation of endothelial dysfunction and ultimately cardiovascular diseases. Under physiologic conditions, reactive oxygen and nitrogen mediators of endothelial cells act to propagate signals driven by different stimuli, by forming molecules with a longer half-life like hydrogen peroxide. Reactive oxygen species (ROS) are constantly produced as a consequence of aerobic metabolism. Under physiologic conditions, their tendency to cause oxidative damage is counterbalanced by the action of antioxidants or oxidant-scavenging enzymes. An imbalance in favour of oxidants leads to oxidat…

Endothelial cells (ECs), are able to manage with higher concentrations of ROS as well as reactive nitrogen species, respect to the other cell types. The unbalance between oxidizing species and antioxidant cellular defences has been implicated in the pathogenesis of cardiovascular diseases. While the role of MPO in the oxidative burst is well established, the effects of this enzyme on endothelial biology have only recently come to light. MPO can interact with endothelial –derived NO causing its depletion and favouring its conversion to nitrogen dioxide radical, a compound responsible of protein nitration generating 3-nitrotyrosine. Moreover, MPO is the only enzyme capable to form hypoclorous…

A close connection: Alzheimer’s disease and type 2 diabetes
2012
In the recent years a growing body of evidence links insulin resistance and insulin action to neurodegenerative diseases, especially Alzheimer’s disease (AD). The importance of insulin in ageing as well as its role in cognition and other aspects of normal brain functions are well established. The hippocampus and cerebral cortex-distributed insulin and insulin receptor (IR) have been shown to be involved in brain cognitive functions. Conversely, deterioration of IR signaling is involved in agingrelated brain degeneration such as in AD and cognitive impairment in type 2 diabetes patients. Insulin administration, while maintaining euglycemia, improves memory in both healthy adults and Alzheime…
