Figure 7. Schematic diagram of APN-induced prevention of human NP cell pyroptosis. APN increases miR-135a-5p levels and then down-regulates TXNIP expression, leading to decreased interaction between TXNIP and NLRP3 in human NP cells stimulated with LPS. Inactivation of the NLRP3 inflammasome inhibits membrane pore formation and subsequent release of IL-1β and IL-18.
