Neuroinflammation can be suppressed by inhibiting NLRP3 inflammasome activation, decreasing neurodegenerative disorder progression. We devised a therapeutic technique that can reduce neuroinflammation induced by microglial activation, avoiding neurodegeneration. We aimed to investigate the mechanisms underlying the pharmacological effects of galantamine and wedelolactone by evaluating the response of the nuclear factor kappa B (NF-κB) signaling pathway and NLRP3 inflammasome in lipopolysaccharide (LPS)-activated N9 microglia.METHODSLPS and adenosine triphosphate were used to activate the NLRP3 inflammasome in N9 microglial cells, which were pretreated with galantamine and wedelolactone. Caspase-1, NLRP3, NF-κB, and interleukin (IL)-1β levels were measured using RT-qPCR and immunostaining.RESULTSCombined administration of galantamine and wedelolactone rescued microglial cells from LPS-induced cell death. Furthermore, treatment with galantamine and wedelolactone led to the suppression of NF-κB expression. NLRP3, caspase-1, and IL-1β levels were decreased by the combined treatment.DISCUSSION AND CONCLUSIONThe concurrent administration of galantamine and wedelolactone effectively suppresses the production of inflammatory cytokines and NLRP3 inflammasome activation in microglia. This inhibitory effect is likely linked to the NF-κB signaling pathway modulation.
