Why don’t we all get Alzheimer's disease?: 85


For researchers like Subhojit Roy, MD, PhD, associate professor in the Departments of Pathology and Neurosciences at the University of California, San Diego School of Medicine, these facts produce a singular question: Why don't we all get Alzheimer's disease?

In a paper published in the August 7 issue of the journal Neuron, Roy and colleagues offer an explanation -- a trick of nature that, in most people, maintains critical separation between a protein and an enzyme that, when combined, trigger the progressive cell degeneration and death characteristic of AD.
