摘　　要：This review addresses the accumulating evidence that live(not decellularized)allogeneic peripheral nerves are functionally and immunologically peculiar in comparison with many other transplanted allogeneic tissues.This is relevant because live peripheral nerve allografts are very effective at promoting recovery after segmental peripheral nerve injury via axonal regeneration and axon fusion.Understanding the immunological peculiarities of peripheral nerve allografts may also be of interest to the field of transplantation in general.Three topics are addressed:The first discusses peripheral nerve injury and the potential utility of peripheral nerve allografts for bridging segmental peripheral nerve defects via axon fusion and axon regeneration.The second reviews evidence that peripheral nerve allografts elicit a more gradual and less severe host immune response allowing for prolonged survival and function of allogeneic peripheral nerve cells and structures.Lastly,potential mechanisms that may account for the immunological differences of peripheral nerve allografts are discussed.
