Objective To review the possible mechanisms of the mammal ian target of rapamycin (mTOR) in the
neuronal restoration process after nervous system injury. Methods The related l iterature on mTOR in the restoration of
nervous system injury was extensively reviewed and comprehensively analyzed. Results mTOR can integrate signals from
extracellular stress and then plays a critical role in the regulation of various cell biological processes, thus contributes to the
restoration of nervous system injury. Conclusion Regulating the activity of mTOR signaling pathway in different aspects can
contribute to the restoration of nervous system injury via different mechanisms, especially in the stress-induced brain injury.
mTOR may be a potential target for neuronal restoration mechanism after nervous system injury.
