NLRP3 and osteoarthritis: We aimed to elucidate the role of the NLRP3 inflammasome in regulating GSDMD-dependent NETosis and to evaluate whether inhibiting NLRP3 or Gasdermin D (GSDMD) alleviates RA pathology.<h4>Methods</h4>Neutrophils and synovial tissues from patients with RA and osteoarthritis (OA) were analyzed for NLRP3, GSDMD, and NET-related markers by immunofluorescence, Western blot, and qPCR.
