Abstract
AbstractObjectiveThe purpose of this study was to investigate resveratrol's specific role as an anti‐inflammatory and osteogenic differentiation of hPDLSCs in periodontitis and to reveal the mechanisms involved.BackgroundNumerous studies have shown that inhibiting the inflammatory response of periodontal tissues and promoting the regeneration of alveolar bone are crucial treatments for periodontitis. Resveratrol has been found to have certain anti‐inflammatory property. However, the anti‐inflammatory mechanism and osteogenic effect of resveratrol in periodontitis are poorly understood.Materials and MethodsWe constructed an in vitro periodontitis model by LPS stimulation of hPDLSCs and performed WB, RT‐qPCR, and immunofluorescence to analyze inflammatory factors and related pathways. In addition, we explored the osteogenic ability of resveratrol in in vitro models.ResultsIn vitro, resveratrol ameliorated the inflammatory response associated with activation of the NF‐κB pathway through activation of the NRF2/HO‐1 pathway, characterized by inhibition of p65/p50 nuclear translocation and the proinflammatory cytokines interleukin‐1β levels. Resveratrol also has a positive effect on osteogenic differentiation.ConclusionsObservations suggest that resveratrol modulates the inflammatory response in hPDLSCs via the NRF2/HO‐1 and NF‐κB pathways and promotes osteogenic differentiation.
