ABSTRACT
<p><b>OBJECTIVE</b>To investigate the effect of cryptoporus polysaccharide(CP)on lipopolysaccharide(LPS)-induced production of monocyte chemoattractant protein-1(MCP-1)in human lung epithelial A549 cells.</p><p><b>METHODS</b>A549 cells were stimulated with LPS in the presence or absence of CP. The protein concentration and mRNA expression of MCP-1 were determined by enzyme-linked-immunosobent assay(ELISA)and semi-quantitative RT-PCR, respectively.</p><p><b>RESULT</b>The protein concentration of MCP-1 was significantly increased by LPS 1000 microg/L at 24 h. There were no effects on the growth and viability of A549 cells in the presence of CP 100 microg/L or dexamethasone 1 mumol/L. However, CP 100 microg/L or dexamethasone 1 micromol/L significantly inhibited the protein concentration and mRNA expression of MCP-1 induced by LPS.</p><p><b>CONCLUSION</b>CP can regulate MCP-1 production, which may be associated with its effects on lung inflammation.</p>
