ScienceDaily (May 31, 2010) — Researchers in the University of Alberta's Faculty of Rehabilitation Medicine have made an important discovery that could lead to more effective treatments for spinal-cord injuries. Karim Fouad and David Bennett have identified one of the body's natural self-repair mechanisms that kick in after injury.
When someone suffers a spinal-cord injury they can lose almost all serotonin projections, so it was previously thought that the serotonin receptors were inactive. But the U of A researchers found that serotonin receptors are spontaneously active after spinal-cord injury, despite the absence of serotonin. Their study shows that this receptor activity is an essential factor in the recovery of functions like walking. Fouad and Bennett say this significant discovery provides important insight into how the spinal cord responds and changes after an injury, which is essential to developing meaningful treatments.
