The aim of this study was to investigate the protective effects of matrine on lipopolysaccharide (LPS)-induced inflammation and oxidative stress in vivo and in vitro. The results showed that matrine improved intestinal inflammatory status and oxidative balance and enhanced chemokine receptor 7 (CCR7) expression. In LPS-challenged mice and Caco-2 cells, matrine alleviated LPS-induced inflammation and oxidative stress via downregulating pro-inflammatory cytokines (IL-1β and IL-17) and malondialdehyde (MDA) production. CCR7-siRNA transfection blocked the protective effects of matrine on LPS-induced inflammation and oxidative stress and exacerbated LPS caused injury. In conclusion, matrine alleviates LPS-induced intestinal inflammation and oxidative stress in mice and Caco-2 cells, which may be associated with CCR7 signal.
本研究旨在探讨苦参碱在体内和体外对脂多糖（LPS）诱导的炎症和氧化应激的保护作用。结果表明，苦参碱改善了肠道炎症状态和氧化平衡，并增强了趋化因子受体7（CCR7）的表达。在LPS刺激的小鼠和Caco-2细胞中，苦参碱通过下调促炎细胞因子（IL-1β和IL-17）和丙二醛（MDA）的产生，减轻了LPS诱导的炎症和氧化应激。CCR7-siRNA转染阻断了苦参碱对LPS诱导的炎症和氧化应激的保护作用，并加剧了LPS所致的损伤。总之，苦参碱减轻了LPS诱导的小鼠和Caco-2细胞的肠道炎症和氧化应激，这可能与CCR7信号有关。
