When the spinal cord is injured, the damaged nerve fibers — called axons — are normally incapable of regrowth, leading to permanent loss of function. An NIH-funded research project in mice is providing insight into why nerves fail to regrow following injury and shows that boosting energy levels within damaged nerves may help them heal.
