Summary

[edit]
Description

One day after head injury (left), bright dye along the edge of the brain suggests damage to the meninges, or the brain’s protective lining. After 35 days (right), the dye no longer appears, indicating the meninges may have healed.

Following head injury, the protective lining that surrounds the brain may get a little help from its friends: immune cells that spring into action to assist with repairs. In a new study, scientists from the National Institutes of Health watched in real-time as different immune cells took on carefully timed jobs to fix the damaged lining of the brain, also known as meninges, in mice. These results may help provide clues to the discovery that the meninges in humans may heal following mild traumatic brain injury (mTBI) and why additional hits to the head can be so devastating.
