The role of the ubiquitin system in the onset and reversal of neuropathic pain

Neuropathic pain (NP) remains one of the world's most difficult problems, and people suffering from NP have their quality of life affected to a great extent and constantly suffer from pain. Sensitization of injurious receptors, ectopic firing of afferent nerves after nerve injury, and coupling between sympathetic and sensory neurons are involved in the onset or development of NP, but the pathogenesis of NP is still not well understood. We found that the ubiquitin system is involved in the pathogenesis of NP and has a crucial role in it. The ubiquitin system can be involved in the onset or reversal of NP by affecting ion channels, cellular signal transduction, glial cells, and the regulation of non-coding RNAs. This provides new ideas for the treatment of NP. The ubiquitin system may be a new effective target for the treatment of NP. A continued, in-depth understanding of the mechanisms of the ubiquitin system involved in NP could further refine the study of analgesic targets and improve pharmacological studies.
