University of Utah researchers identify Arc protein's role in Alzheimer's
Discovery of Arc protein reveals how toxic Tau spreads.
Event Overview
Researchers at the University of Utah Health identified a brain protein called Arc that facilitates the spread of toxic Tau proteins between neurons in Alzheimer's patients. The study, published in the journal Cell, found that Arc packages Tau into extracellular vesicles to move it from damaged neurons to healthy ones. While Arc helps the disease spread, it also provides a protective benefit by helping sick neurons expel excess Tau to survive longer. Experiments with mice showed that removing the Arc protein significantly reduced Tau transmission.
