Researchers found two groups of brain cells in mice that control anxiety. One group of these immune cells, called microglia, can increase anxiety. The other group decreases anxiety. This is a big discovery in how we understand anxiety.
When the cells that increase anxiety were active, the mice showed anxious behavior. However, when the cells that reduce anxiety were active, the mice remained calm.
This information can help improve treatments for anxiety conditions in humans.
