Sponsor's own description
Consistent evidence suggests that mitochondrial dysfunction plays a crucial role in Parkinson¿s disease pathogenesis. Inhibition of complex I of the mitochondrial electron transport chain is sufficient to reproduce biochemical and pathological features of Parkinson¿s Disease in animal models (PD). Alterations of mitochondrial energy metabolism may intervene in PD pathogenesis by inducing inflammation, generation of reactive oxygen species (ROS), and neurodegeneration. The Nuclear factor erythroid 2-related factor 2 (Nrf2) is a regulator both of mitochondrial function and biogenesis, and of cellular resistance to oxidative stress, and may represent a novel target of PD disease-modifying therapies. The aims of the present study are to validate indicators of energy metabolism as biomarkers in PD patients and to evaluate the efficacy of drugs and natural food supplements acting on the Nrf2 pathway in improving motor impairment and Gait in PD patients.
