|Abstract:||Axons in the mature mammalian central nervous system have only a limited capacity to grow/regenerate after injury, and spontaneous recovery of motor functions is therefore not greatly expected in spinal cord injury (SCI). To promote functional recovery after SCI, it is critical that corticospinal tract (CST) fibers reconnect properly with target spinal neurons through enhanced axonal growth/regeneration. Here, we applied antibody treatment against repulsive guidance molecule-a (RGMa) to a monkey model of SCI. We found that inhibition of upregulated RGMa around the lesioned site in the cervical cord resulted in recovery from impaired manual dexterity by accentuated penetration of CST fibers into laminae VII and IX, where spinal interneurons and motoneurons are located, respectively. Furthermore, pharmacological inactivation following intracortical microstimulation revealed that the contralesional, but not the ipsilesional, primary motor cortex was crucially involved in functional recovery at a late stage in our SCI model. The present data indicate that treatment with the neutralizing antibody against RGMa after SCI is a potential target for achieving restored manual dexterity in primates.|
