Current therapeutic approaches are insufficient to address these challenges. In this study, we investigated whether exogenous hydrogen sulfide (H<jats:sub>2<\/jats:sub>S) can modulate neuroinflammatory responses and remodel the injury microenvironment to promote tissue repair and restore motor function following SCI.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>T10 crush SCI was induced in mice, followed by daily intraperitoneal administration of the H<jats:sub>2<\/jats:sub>S donor anethole trithione (ADT).
