Researchers at the famed Cleveland Clinic say they have reversed the effects of Alzheimer’s disease in afflicted mice.Scientists say they have discovered that the gradual depletion of an enzyme called BACE1 completely reversed the formation of amyloid plaques. That enzyme depletion led to the improvement of the animal’s cognitive function. “To our knowledge, this is the first observation of such a dramatic reversal of amyloid deposition in any study of Alzheimer’s disease mouse models,” said Dr. Riqiang Yan. The success of the animal trial gives hope the procedure can one day be used to treat humans.
