Nigericin sodium salt is an antibiotic from Streptomyces hygroscopicus and is a NLRP3 activator.Nigericin sodium is a cationic ionophore that inhibits Golgi function and suppresses growth of gram positive bacteria. It also prevents viral activation and triggers activation of the NALP3 inflammasome.A 48-hr exposure of human erythrocytes to nigericin significantly increased the percentage of annexin-V-binding cells (0.1-10 nM), significantly decreased forward scatter (0.1-1 nM), significantly decreased cytosolic pH (0.1-1 nM) and significantly increased Fluo3 fluorescence (0.1-10 nM). Nigericin (1 nM) slightly, but significantly, increased ROS, but did not significantly modify ceramide abundance. The effect of nigericin on annexin V binding was significantly blunted, but not abolished by removal of extracellular Ca(2+). The nigericin-induced increase in [Ca(2+)]i and annexin V binding was again significantly blunted but not abolished by the Na(+)/H(+) exchanger inhibitor cariporide (10 μM). Nigericin triggers eryptosis, an effect paralleled by ROS formation, in part dependent on stimulation of Ca(2+) entry, and involving the cariporide-sensitive Na(+)/H(+) exchanger.
