Objective To discuss peripheral nerve regeneration under immunosuppression. Methods Current research trends about relationship between peripheral nerve injury and immunoreaction, the experimental result of nerve regeneration after using various immunosuppressors, and the clinical findings after human allogenous hand transplantation were extensively reviewed. Results Peripheral nerve regeneration was accelerated under immunosuppression. Conclusion Peripheral nerve injury may induce immunoreaction, which inhibit nerve regeneration and function recovery.
