Peripheral nerve injury (PNI) may lead to disability and neuropathic pain, which constitutes a substantial economic burden to patients and society. It was found that the peripheral nervous system (PNS) has the ability to regenerate after injury due to a permissive microenvironment mainly provided by Schwann cells (SCs) and the intrinsic growth capacity of neurons; however, the results of injury repair are not always satisfactory. Effective, long-distance axon regeneration after PNI is achieved by precise regulation of gene expression. Numerous studies have shown that in the process of peripheral nerve damage and repair, differential expression of non-coding RNAs (ncRNAs) significantly affects axon regeneration, especially expression of microRNAs (miRNAs), long non-coding RNAs (lncRNAs) and circular RNAs (circRNAs). In the present article, we review the cellular and molecular mechanisms of axon regeneration after PNI, and analyze the roles of these ncRNAs in nerve repair. In addition, we discuss the characteristics and functions of these ncRNAs. Finally, we provide a thorough perspective on the functional mechanisms of ncRNAs in nervous injury repair, and explore the potential these ncRNAs offer as targets of nerve injury treatment.
