The New York Times - Path Is Found for the Spread of Alzheimer’s

 – February 1, 2012  –– 

Alzheimer’s disease seems to spread like an infection from brain cell to brain cell, two new studies in mice have found. But instead of viruses or bacteria, what is being spread is a distorted protein known as tau. Over the next two years, the cell death and destruction spread outward to other cells along the same network. Since those other cells could not make human tau, the only way they could get the protein was by transmission from nerve cell to nerve cell. And that, said Dr. Samuel E. Gandy, associate director of the Alzheimer’s Disease Research Center at Mount Sinai School of Medicine, was “very unexpected, very intriguing.”
