Description
Summary:Dental caries is a highly prevalent chronic disease that leads to dental pulp inflammation. It is treated by removing the damaged tooth structure and applying a material that promotes resolution of pulpal inflammation. Tumor necrosis factor superfamily 14 (TNFSF14) is an immunomodulatory cytokine and a member of the TNF superfamily. This study aimed to evaluate the effect of TNFSF14 on the levels of inflammatory cytokines involved in pulpal inflammation using lipoteichoic acid (LTA)-induced human dental pulp stem cells (hDPSCs). hDPSCs were cultured and induced with LTA, followed by treatment with TNFSF14 at 25 and 50 ng/mL. Cellular viability was evaluated using the Alamar Blue assay. The levels of inflammatory cytokines IL-6, IL-8, IL-10, and TNF-α were quantified using reverse transcription–quantitative polymerase chain reaction (RT–qPCR) and enzyme-linked immunosorbent assay (ELISA). TNFSF14 at 25 and 50 ng/mL significantly reduced the mRNA and protein levels of pro-inflammatory cytokines <i>TNF-α</i>, <i>IL-6</i>, and <i>IL-8</i>, and increased the anti-inflammatory cytokine <i>IL-10</i>. In addition, TNFSF14-treated groups enhanced cell viability. Adding TNFSF14 to LTA-induced hDPSCs regulated the production of inflammatory cytokines by lowering the levels of IL-6, IL-8, and TNF-α and elevating IL-10 levels.
