A widely studied anti-aging drug combination caused severe brain damage in mice. Researchers found that the treatment damaged myelin, a protective coating around nerve fibers.

Mice are often used to test new treatments and medicines. Recently, scientists at the University of Connecticut discovered that a popular anti-aging drug combination, called dasatinib+quercetin (D+Q), caused severe brain damage in mice. This is concerning because D+Q has been studied for its potential to slow down aging and even reverse age-related diseases like Alzheimer's disease and type II diabetes.

The researchers found that the treatment damaged myelin, a protective coating around nerve fibers that helps electrical signals travel efficiently through the brain and body. When this myelin is damaged, it can lead to numbness, pain, difficulty walking, and problems with memory and thinking. This damage is similar to what happens in people with multiple sclerosis.

The researchers also found that the oligodendrocytes, specialized brain cells responsible for producing and maintaining myelin, regressed into a more juvenile form when exposed to D+Q. This could provide important clues about how multiple sclerosis develops.

New research is now exploring whether these damaged cells can be restored and encouraged to repair the brain.

Why It Matters

This study matters because it highlights the importance of carefully testing new treatments before they are used in humans. As people seek ways to stay healthy and youthful, it's crucial that we understand the potential risks and side effects of anti-aging therapies.
