Role of inflammation in the secondary injury following experimental spinal cord trauma

The primary traumatic mechanical injury to the spinal cord causes the death of a number of neurons that cannot be recovered, neither regenerated. However, neurons continue to die for hours after spinal cord injury (SCI), and this represents a potentially avoidable event. One of mechanisms that have been touted to contribute importantly to the evolution of such secondary cell death is the local inflammatory response in the injured spinal cord. In this report we have used an in vivo model to induce acute SCI and reproduce the acute pathological events associated with inflammation after traumatic SCI in rats.
