Because mitochondria play a central role in cellular homeostasis, mitochondrial impairment is considered an important component of SCI pathophysiology. We investigated the effects of exenatide, a glucagon-like peptide-1 (GLP-1) receptor agonist, on mitochondrial dysfunction after SCI using a rat contusion model and C6 glioma cells. Exenatide was associated with increased OPA1 expression and enhanced Drp1 phosphorylation at Ser637, suggesting a shift in mitochondrial dynamics toward fusion-dominant regulation. Exenatide also tended to increase the expression of Bcl-2, HO-1, and p62.\n                    <jats:italic toggle=\"yes\">In vitro<\/jats:italic>\n                    , exenatide attenuated H\n                    <jats:sub>2<\/jats:sub>\n                    O\n                    <jats:sub>2<\/jats:sub>\n                    - and CCCP-induced reductions in cell viability, preserved mitochondrial membrane potential, and reduced the proportion of dead cells.
