Abstract:
Spinal cord ischemia/reperfusion injury is a devastating medical disorder with poor prognosis that is associated with several pathophysiological conditions. However, multiple stimuli can trigger SCII, so the underlying mechanism of this pathology has not yet been fully established. MicroRNAs (miRNAs) are a class of non-coding RNAs that mediate a variety of nervous system diseases and regulate numerous physiological functions, including apoptosis, autophagy, inflammation, and blood-spinal cord barrier damage. miRNA expression profiles are known to be altered after spinal cord ischemia/reperfusion injury. Therefore, gaining a better understanding of the significant roles that miRNAs play in spinal cord ischemia/reperfusion injury could help develop potential preventive and therapeutic strategies for spinal cord ischemia/reperfusion injury. This review summarizes the current state of our knowledge about the relationship between miRNAs and spinal cord ischemia/reperfusion injury, as well as potential miRNAs that could be targeted to treat spinal cord ischemia/reperfusion injury.
