Scientists Uncover Pathways of Alzheimer’s Spread and Potential Slowdown

Researchers at the University of Utah Health have discovered how Alzheimer’s disease spreads in the brain. This finding could help develop new treatments that slow the disease instead of just removing harmful proteins after the damage is done.

The study showed that a brain protein called Arc helps nerve cells, or neurons, send messages. However, it also assists the spread of toxic Tau, a protein linked to Alzheimer’s. Arc carries Tau out of damaged neurons and into healthy ones, leading to more problems.

Dr. Christopher U. Missling, who leads a biotechnology company, explained that this research changes how scientists understand the disease. For years, they mainly looked at Tau building up inside neurons but did not fully consider how it spreads between cells.

The team compared mice with Alzheimer’s to those without the Arc protein. They found that removing Arc reduced the spread of Tau. While Arc helps neurons survive in early disease stages, simply blocking it may not be effective.

The researchers found Tau and Arc in human brain tissue, suggesting that the same process could happen in people. They warn that more studies are needed, but this discovery could open doors for future treatments aiming to slow Alzheimer’s.
