BACKGROUNDThe ADORA1 is known to provide renoprotection against acute kidney injury. However, the underlying mechanisms remain unclear. The purpose of this study was to investigate whether and how ADORA1 plays a role in renoprotection in sepsis associated acute kidney injury (SA-AKI).METHODSSepsis model was induced by lipopolysaccharide (LPS) in male C57BL/6 mice, 0.9 % NS served as controls. Animals received ADORA1 agonists and antagonist before the LPS. Renal function, histology and pyroptosis markers were assessed, with simultaneous validation by vitro assays.RESULTSThe animals treated with ADORA1 agonists exhibited higher survival rates and an improved renal functional recovery, attenuated histological lesions and downgraded pyroptosis. Moreover, which down-regulated the expression of cleaved caspase 11 and GSDMD, while the ADORA1 antagonist group exhibit an oppose results.CONCLUSIONSADORA1 protects against SA-AKI, at least in part, through its inhibitory effects on pyroptosis via the noncanonical inflammasome pathway. If our finding may extrapolated to clinical setting, ADORA1 agonist may serve as a clinical strategy to SA-AKI.
