Microglial activation and polarization significantly influence this response, with pro\u2010inflammatory (M1) polarization exacerbating damage and anti\u2010inflammatory (M2) polarization promoting repair. MS4A7, a membrane\u2010bound protein involved in immune regulation, has been implicated in inflammation, but its role in SCI remains unexplored. This study investigates the function of MS4A7 in modulating microglial polarization and its downstream effects on the inflammatory response in SCI, focusing on the cGAS\u2010STING\u2010NLRP3 axis.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>A combination of in\u00a0vivo and in\u00a0vitro approaches, including mouse SCI models and BV2 microglial cells, was employed. Differential gene expression analysis was conducted using the GSE93561 dataset. MS4A7 expression was modulated using shRNA and overexpression plasmids. Microglial polarization was assessed via immunofluorescence, RT\u2010qPCR, and ELISA for M1 (iNOS, IL\u20101\u03b2, TNF\u2010\u03b1) and M2 (Arg1, IL\u201010, CD206) markers. Pyroptosis and inflammasome activation were examined using PI staining, LDH release, and NLRP3\/GSDMD assays. The role of the cGAS\u2010STING pathway was evaluated using activators (diABZI) and inhibitors (C\u2010176), and NLRP3 inflammasome activity was pharmacologically inhibited with MCC950.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      MS4A7 was significantly upregulated in SCI tissues (\n                      <jats:italic>p<\/jats:italic>\n                      \u2009&lt;\u20090.01). Knockdown of MS4A7 reduced M1 markers (iNOS, IL\u20101\u03b2, and TNF\u2010\u03b1) and increased M2 markers (Arg1, IL\u201010, and CD206), promoting anti\u2010inflammatory polarization (\n                      <jats:italic>p<\/jats:italic>\n                      \u2009&lt;\u20090.05).
