Improved recovery after spinal cord trauma in ICAM-1 and P-selectin knockout mice.

Traumatic spinal cord injury is followed by infiltration of leukocytes, influenced by endothelial adhesion molecules such as ICAM-1 and P-selectin. In order to evaluate the pathogenetical role of these molecules, wild-type mice and mice lacking ICAM-1 and P-selectin were subjected to an experimental spinal cord compression of two degrees of severity. Hind limb motor function decreased after injury in all animals but the groups of injured ICAM-1/P-selectin knockout animals had a better functional outcome during the entire observation period of 14 days. This difference was statistically significant on day 1. Our results indicate that adhesion molecules influence the functional outcome after spinal cord injury in a negative way and may be a target for future therapy of neurotrauma.
