In this study, our results revealed that\n              <jats:italic toggle=\"yes\">P. gingivalis<\/jats:italic>\n              exacerbated inflammation, as indicated by weight loss, decreased colon length, and increased colonic tissue inflammation. Furthermore,\n              <jats:italic toggle=\"yes\">P. gingivalis<\/jats:italic>\n              increased the population of Th17 cells in the spleen and upregulated the expression of pro-inflammatory cytokines in mice. Additionally,\n              <jats:italic toggle=\"yes\">P. gingivalis<\/jats:italic>\n              aggravated the gut microbiota dysbiosis by reducing the beneficial bacteria like S24-7. In addition, we discovered that paeoniflorin, a widely recognized biologically active phytochemical, had the potential to mitigate the exacerbated inflammation caused by\n              <jats:italic toggle=\"yes\">P. gingivalis<\/jats:italic>\n              . Specifically, paeoniflorin treatment rebalanced immune cell populations, reduced the levels of inflammatory cytokines, and reshaped the composition of the gut microbiota. In summary, our findings suggest that paeoniflorin holds promise as a potential therapeutic agent for alleviating the inflammatory effects induced by\n              <jats:italic toggle=\"yes\">P. gingivalis<\/jats:italic>\n              .\n            <\/jats:p>\n            <jats:sec>\n              <jats:title>IMPORTANCE<\/jats:title>\n              <jats:p>\n                <jats:italic toggle=\"yes\">Porphyromonas gingivalis<\/jats:italic>\n                may reach the gastrointestinal tract and establish colonization.
