Dorsal root ganglion neurons exhibit a robust and generally successful regenerative response following injury of their peripheral processes. Regeneration fails, however, after section of their central processes in the dorsal roots or dorsal columns. Experiments characterizing the attenuated response of these neurons to injury, and the inhibition of regeneration exerted by astrocytes and oligodendrocytes within the dorsal root entry zone and spinal cord, have contributed important insights into the failure of regeneration after injury to the central nervous system (CNS). Interventions that have enhanced the metabolic response of injured dorsal root ganglion neurons, and altered the inhospitable environment, have increased sensory afferent regeneration and recovery. There is reason to expect that these strategies will help to develop clinically applicable treatments of CNS injuries.
