The main system of mercury toxicity includes its irreversible inhibition of selenoenzymes, such as thioredoxin reductase (IC50 = nine nM).[53] Even though it has a lot of functions, thioredoxin reductase restores nutritional vitamins C and E, in addition to a number of other important antioxidant molecules, back again into their lessened sorts, enabling them to counteract oxidative hurt.[fifty four] Since the price of oxygen usage is especially significant in Mind tissues, production of reactive oxygen species (ROS) is accentuated in these vital cells, creating them specifically prone to oxidative hurt and particularly dependent on the antioxidant protection supplied by selenoenzymes.
