Schematic model for the reduction of IL-1β and IL-18 secretion in LPS-primed and ATP-stimulated macrophages treated with HSM.
The HSM extract down-regulated P2X7R expression, ROS production, NLRP1 expression and caspase-1 and caspase-4 activation, which together inhibited the secretion of IL-1β and IL-18. TLR4: Toll-like receptor 4.
