Acid‐sensing ion channels regulate nucleus pulposus cell inflammation and pyroptosis via the NLRP3 inflammasome in intervertebral disc degeneration

Extracellular lactate regulates levels of intercellular reactive oxygen species (ROS) through ASIC1 and ASIC3. ROS activate the NF-κB signalling pathway, thus promoting NLRP3 inflammasome activation and IL-1β release, both of which promote NP degeneration.
