- Abstract
- Matrix metalloproteinase-9 (MMP-9) is considered to be an important component in the progression of inflammation. Monocytes/macrophages are prominent at inflammation sites, and activation of these cells by stimulants such as lipopolysaccharide (LPS) leads to the production of significant amounts of MMP-9. Here, we show that LPS-induced MMP-9 production and activation was inhibited by the water extract from the fruit of Chaenomeles sinensis (CS), the root of Polygonum cuspidatum (PC), but increased by the extract from Boswellia carterii (BC). To investigate the mechanism by which those extracts inhibits MMP-9 activation, we examined the level of MMP-9 mRNA expression. We observed a significant change in the MMP-9 expression between LPS alone and LPS plus Chaenomeles sinensis and Polygonum cuspidatum extracts-treated cells. In addition, LPS significantly up-regulated MMP-9 promoter activity in Raw 264.7 cells, which was attenuated by the CS and PS extracts. However, water extracts from Boswellia carterii increased MMP-9 expression and MMP-9 promoter activity which were induced by LPS treatment in Raw 264.7 cells. These data suggest that water extracts from Chaenomeles sinensis and Polygonum cuspidatum can modulate anti-inflammatory immune response, which may be in part associated with the regulation of MMP-9 production and/or activation through the regulation of MMP-9 expression in mouse macrophage cells.
