GAS mitigated the inflammatory response by reducing M1 markers (iNOS and CD86) and augmenting M2 markers (Arg1 and CD206) within the injured spinal cord and BV2 microglia. Additionally, GAS exhibited a direct anti\u2010apoptotic effect on neurons in co\u2010culture. Mechanistically, GAS significantly activated the PI3K\/AKT signaling pathway. Notably, the PI3K inhibitor LY294002 completely nullified the anti\u2010inflammatory and anti\u2010apoptotic effects of GAS, underscoring the central role of this pathway in mediating GAS's effects.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>This study demonstrates that GAS confers multifaceted protection against SCI by modulating microglial polarization from the pro\u2010inflammatory M1 phenotype to the anti\u2010inflammatory M2 phenotype and by directly inhibiting neuronal apoptosis, primarily through activation of the PI3K\/AKT signaling pathway.
