Inhibition of Nogo: A key strategy to increase regeneration, plasticity and functional recovery of the lesioned central nervous system

In the adult central nervous system (CNS) myelin and oligodendrocytes, Nogo-A exerts a growth inhibitory function leading to restricted axonal regeneration. After development of different anti-Nogo-A antibodies and other Nogo-A blocking reagents their application has recently been studied in various in vivo animal models of spinal cord injury and stroke. These studies show that intracerebral application of Nogo-A-inactivating reagents leads to enhanced regeneration and compensatory sprouting, structural reorganization or plasticity, and functional recovery as seen in different behavioural analyses.
