Several studies carried out by the Ebadi group have shown in the brain of mice from transgenic and knockout PD models that induction of MT is involved in the synthesis of coenzyme Q10, through the activation of lipoamide dehydrogenase, enhancing the antioxidant capacity of coenzyme Q10 Ubiquinone, by increasing the ubiquinol synthesis, attenuation of a-synuclein nitration, as well as suppression of proinflammatory cytokines and TNFa [50].
