Miracles and molecules--progress in spinal cord repair

Severe spinal cord injury (SCI) leads to devastating loss of neurological function below the level of injury and adversely affects multiple body systems. Most basic research on SCI is designed to find ways to improve the unsatisfactory cellular and molecular responses of spinal cord to injury, which include an array of early processes of autodestruction and a subsequent lack of functional tissue repair. This research has brought us to the threshold of practical application along three lines of approach, derived from animal model studies: acute neuroprotection, enhanced axonal regeneration or plasticity, and treatment of demyelination. There is a growing commercial interest in this previously neglected therapeutic area.
