Harnessing the immune system to treat traumatic brain injury in mice

Researchers have designed a targeted therapeutic treatment that restricts brain inflammation. The effectiveness of this approach in improving outcomes was demonstrated following brain injury, stroke or multiple sclerosis in mice. The system increases the number of regulatory T cells, mediators of the immune system’s anti-inflammatory response, in the brain. By boosting the number of T regulatory cells in the brain, the researchers were able to prevent the death of brain tissue in mice following injury and the mice performed better in cognitive tests. The treatment has a high potential for use in patients with traumatic brain injury, with few alternatives currently available to prevent harmful neuroinflammation.
