Abstract
Porphyromonas gingivalis is a periodontopathogenic bacterium that can adhere and colonize periodontal tissues leading to inflammatory process, and consequently tissue destruction. New therapies using flavonoids such as hesperidin are being studied, and its promising properties have been highlighted. The aim of this study was to evaluate the effect of hesperidin on epithelial barrier function, reactive oxygen species (ROS) production and on inflammatory response caused by P. gingivalis in in vitro models. Integrity of the epithelial tight junctions challenged by P. gingivalis was determined by monitoring the transepithelial electrical resistance (TER). P. gingivalis adherence to a gingival keratinocyte monolayer and a basement membrane model were evaluated by a fluorescence assay. A fluorometric assay was used to determine the ROS production in gingival keratinocytes. The level of pro-inflammatory cytokines and matrix metalloproteinases (MMPs) secretion was evaluated by ELISA, while to assess NF-κB activation, the U937-3xjB-LUC monocyte cell line transfected with a luciferase reporter gene was used. Hesperidin protected against gingival epithelial barrier dysfunction caused by P. gingivalis and reduced the adherence of P. gingivalis to the basement membrane model. Hesperidin dose-dependently inhibited P. gingivalis-mediated ROS production by oral epithelial cells as well as the secretion of IL-1β, TNF- IL-8, MMP-2 and MMP-9 by macrophages challenged with P. gingivalis. Additionally, it was able to attenuate NF-κB activation in macrophages stimulated with P. gingivalis. These findings suggested that hesperidin has a protective effect on the epithelial barrier function, in addition to reduce ROS production and attenuate the inflammatory response associated with periodontal disease.
