ABSTRACT
<p><b>OBJECTIVE</b>To study the effect of Lycium bararum polysaccharides (LBPs) stimulation on the maturation of murine bone marrow derived dendritic cells (BMDCs).</p><p><b>METHODS</b>Murine bone marrow cells were cultured in GM-CSF and IL-4 for 5 days, then were purified with a MACS column. Respectively, BMDCs were stimulated with LBPs, LPS and RPMI1640 for 2 days. Cell phenotypes and antigens uptake by BMDCs were analyzed by flow cytometry. Cytokines released by BMDCs were detected. The antigen presenting by BMDCs was evaluated by mixed lymphocyte responses.</p><p><b>RESULT</b>Compared with to the BMDCs that only subjected to RPMI 1640, the expression of I-A/I-E, CD11c and secretion of IL-12 by BMDCs stimulated with LBPs were increased, the phagocytosis of FITC-dextran by BMDCs stimulated with LBPs was impaired but the activation of proliferation of allogenic lymphocytes by BMDCs was strengthened.</p><p><b>CONCLUSION</b>LBPs promote not only the maturation of cultured murine BMDCs in vitro, but also the immune response initiation induced by BMDCs.</p>
