Study Shows Toxic Alzheimer’s Protein Spreads Through Brain Via Extracellular Space

New York, NY (Scicasts) — A toxic Alzheimer’s protein can spread through the brain–jumping from one neuron to another–via the extracellular space that surrounds the brain’s neurons, suggests new research from Columbia University Medical Center. The study has been published online in Nature Neuroscience. The spread of the protein, called tau, may explain why only one area of the brain is affected in the early stages of Alzheimer’s but multiple areas are affected in later stages of the disease. “By learning how tau spreads, we may be able to stop it from jumping from neuron to neuron,” said Dr. Karen Duff, professor in the department of pathology and cell biology (in the Taub Institute for Research on Alzheimer’s Disease and the Aging Brain) and professor of psychiatry (at New York…
