Scripps Research Institute Scientists Help Unravel a Central Mystery of Alzheimer’s Disease

Scientists at The Scripps Research Institute (TSRI) have shed light on one of the major toxic mechanisms of Alzheimer’s disease. The discoveries could lead to a much better understanding of the Alzheimer’s process and how to prevent it.

The findings, reported in the April 10, 2013 issue of the journal Neuron, show that brain damage in Alzheimer’s disease is linked to the overactivation of an enzyme called AMPK. When the scientists blocked this enzyme in mouse models of the disease, neurons were protected from loss of synapses-neuron-to-neuron connection points-typical of the early phase of Alzheimer’s disease.
