Mechanism explains link between apolipoprotein E and Alzheimer's disease

Scientists have discovered a previously unknown mechanism by which apolipoprotein E, a molecule whose mutation is linked to Alzheimer's disease (AD), stimulates degradation of sticky amyloid beta (A-beta) protein within the brain. The research, published by Cell Press in the June 12 issue of the journal Neuron, may lead to a powerful new therapy for this devastating disease.
