The mechanism diagram shows that IRF7 and IRF3 can serve as intermediate signals for STING and NLRP3, linking the mtDNA–cGAS–STING axis and NLRP3–pyrotosis axis to further explain the molecular mechanism by which STING regulates the activation of NLRP3 inflammasomes. Inhibiting multiple molecules from mtDNA to NLRP3 can reduce macrophage pyroptosis and improve SAP-ALI
