Subject: Why wounds heal more slowly with age
Our bodies undergo many changes when we age. Once potentially problematic change is that our bodies take longer to heal when we are older. This phenomenon has been observed since WWI. Recent studies at Rockefeller University have focused on observing young and elderly mice to determine why this happens. It has been discovered that our immune cells stop communicating effectively in old age, which leads to them not doing their jobs as quickly as when we are young.
- Yet until now, researchers have not been able to tease out what age-related changes hinder the body's ability to repair itself.
- Both skin cells and immune cells contribute to this elaborate process, which begins with the formation of a scab.
- The scientists hope the same principle could be applied to developing treatments for age-related delays in healing.
