Abstract: Objective · To investigate the effects of procyanidin B2 on the of inflammatory mediators in human periodontal ligament cells (hPDLCs) inducedPorphyromonas gingivalis lipopolysaccharide (LPS). Methods · hPDLCs were cultured using tissue explant method in vitro. The effect of procyanidin B2 on the cell viability of hPDLCs was detectedMTT assay. hPDLCs were stimulatedP. gingivalis LPS after treatment with procyanidin B2 for 1 h. The s of IL-1β, IL-6, and IL-8 mRNA and proteins were detectedreal-time PCR and ELISA assay. Reactive oxygen species (ROS) in the cytoplasm was observed under fluorescence microscope. Nitric oxide (NO) in the supernatant was detectedGriess assay. Results · 100.00 μg/mL procyanidin B2 could enhance the cell viability of hPDLCs. Procyanidin B2 could inhibit the s of IL-1β, IL-6, and IL-8 mRNA and proteins in hPDLCs. It could also downregulate ROS and NO in hPDLCs inducedP. gingivalis LPS. Conclusion · Procyanidin B2 can play an anti-inflammatory roleinhibiting inflammatory mediators in hPDLCs inducedP. gingivalis LPS.
