Abstract
Inflammation regulation is essential for maintaining healthy functions and normal homeostasis of the body. Porphyromonas gingivalis (P. gingivalis) is a gram-negative anaerobic bacterium and a major pathogen that causes oral inflammation and other systemic inflammations. This study aims to examine the anti-inflammatory effects of Agrimonia pilosa Ledeb root extracts (APL-ME) in Porphyromonas gingivalis LPS-induced RAW 264.7 cells and find anti-inflammatory effect compounds of APL-ME. The anti-inflammatory effects of APL-ME were evaluated anti-oxidant activity, cell viability, nitrite concentration, pro-inflammatory cytokines (interleukin-1[Formula: see text], interleukin-6, tumor necrosis factor (TNF)-[Formula: see text], and anti-inflammatory cytokine (interleukin-10 (IL-10)). Also, Inflammation related genes and proteins, cyclooxygenase (COX)-2, inducible nitric oxide synthase (iNOS), expression were decreased by APL-ME and mitogen-activated protein kinase (MAPK) signaling proteins expression was regulated by APL-ME. Liquid chromatography-mass spectrometer (LC/MS)-MS analysis results indicated that several components were detected in APL-ME. Our study indicated that APL-ME suppressed nitrite concentrations, pro-inflammatory cytokines such as IL-1[Formula: see text], IL-6 and TNF-[Formula: see text] in P. gingivalis LPS induced RAW 264.7 cells. However, IL-10 expression was increased by ALP-ME. In addition, protein expressions of COX-2 and iNOS were inhibited APL-ME extracts dose-dependently. According to these results, APL-ME has anti-inflammatory effects in P. gingivalis LPS induced RAW 264.7 cells.
