Abstract:
Recent discoveries have emphasized the critical role of oxidized DNA (ox-DNA) in inflammation and immune regulation. Produced during oxidative stress from infection or tissue damage, ox-DNA activates signaling pathways that drive the release of proinflammatory cytokines, specifically engaging the NLRP3 inflammasome, a key player in cytokine maturation and host defense. NLRP3 is increasingly implicated in inflammatory and autoimmune diseases, with ox-DNA recognized as a central activator of this inflammasome. This review examines the role of ox-DNA in inflammasome activation, its broader impact on inflammatory processes, and promising therapeutic approaches targeting ox-DNA through both immunological and structural lenses. These insights highlight ox-DNA's relevance in inflammation and offer potential avenues for the treatment of a range of immune-related disorders.
