Figure Lengend Snippet: A schematic representation of the proposed model: ASIC1a is involved in renal IRI via the NF-κB/NLRP3 inflammasome. ASIC1a is activated by ischemia-induced extracellular acidosis and subsequently causes activation of NF-κB. NF-κB upregulates the expression of NLRP3 and IL-1β precursor and promotes activation of the NLRP3 inflammasome, which results in renal IRI. Inhibition of NF-κB pathway mitigates the activating effect of ASIC1a toward the NLRP3 inflammasome. Inhibiting ASIC1a by gene deletion or chemical agent protects against renal IRI. ASIC1a mediating the NLRP3 inflammasome activation by NF-κB pathway is critical in AKI. ASIC1a may represent a potential therapeutic target for AKI
