The activity of NLRP3 inflammasome by PG-LPS destroys the periodontal ligament by inducing a periodontal inflammatory reaction and inhibiting proinflammatory cyto-kines such as IL-1β, IL-6, and TNF-α against these pathogen infections, and mediators have been important in the treatment of periodontitis [32,33]. The gene discussed is NLRP3; the disease is infection.
