Neuroinflammation triggers sequelae after spinal cord injury (SCI). Inhibition of inflammation promotes recovery after SCI. MicroRNAs regulate many pathophysiological processes, including inflammation. Any role for miR-181a-5p in the inflammatory response after SCI remains unclear. Thus, we evaluated the effects of miR-181a-5p on inflammation in PC12 cells and the underlying mechanism in play. ⋯ miR-181a-5p attenuated the inflammatory response of LPS-induced PC12 cells by directly inhibiting HMGB1; thus, miR-181a-5p may serve as a therapeutic target in SCI.
