Summary:
As Alzheimer's Disease (AD) progresses, brain
metabolism gradually declines as damage to nerve cells caused by oxidative
stress occurs. The metabolic decline correlates with reductions in certain
enzymes within mitochondria, the energy Ôgenerators' of the cell. As a by
product of their biochemical reactions, mitochondria produce oxidative
stress. Oxidative stress and altered mitochondrial function can be plausibly
linked to the formation of plaques and tangles, to memory deficits and to
inflammation Ð all of which are present in brains of AD patients. The goal of
the proposed studies is to test whether the use of resveratrol (a component
of red wine and an antioxidant) can reverse or delay the inflammation and
oxidative stress, reduce the formation of plaques, and minimize the memory
deficits that occur in animal models of plaque formation. This could form the
basis for development of treatment strategies using resveratrol or its
derivatives.
