The limited plastic and regenerative capabilities of axons in the adult mammalian CNS can be enhanced by the application of a monoclonal antibody (mAb), IN-1, raised against the myelin-associated neurite growth inhibitor Nogo-A. The aim of the present study was to investigate the effects of this treatment on the functional recovery of adult rats with a dorsal over-hemisection of the spinal cord. Directly after injury, half of the animals were implanted with mAb IN-1-secreting hybridoma cells, whereas the others received cells secreting a control antibody (anti-HRP). A broad spectrum of locomotor tests (open field locomotor) score, grid walk, misstep withdrawal response, narrow-beam crossing) was used to characterize locomotor recovery during the 5 weeks after the injury. In all behavioral tests, the recovery in the mAb IN-1-treated group was significantly augmented compared with the control antibody-treated rats. EMG recordings of flexor and extensor muscles during treadmill walking confirmed the improvement of the locomotor pattern in the mAb IN-1-treated rats; step-cycle duration, rhythmicity, and coupling of the hindlimbs were significantly improved. No differences between the two groups with regard to nociception were observed in the tail flick test 5 weeks after the operation. These results indicating improved functional recovery suggest that the increased plastic and regenerative capabilities of the CNS after Nogo-A neutralization result in a functionally meaningful rewiring of the motor systems.
