RECOVERY FROM PERIPHERAL NEUROPATHY
The peripheral nervous system has the ability to recover after injury[61]
Fortunately the axon of the PNS can "repair themselves" and regain function after injury, which does not occur with CNS axons[61,62].
Spontaneous peripheral nerve repair is possible thanks to the considerable plasticity of Schwann cells. Thus, after a nerve injury, the Schwann cells initiate a repair and regeneration programme that promotes the survival of neurons, the disintegration of the damaged axon and the remyelination of the regenerated axon, among other processes[63].
Both the presence of molecules external to the neuron (extracellular) and the neuron's own growth capacity influence the success of this regenerative process[61].
