Abstract:
:We investigated whether Candida beta-D-glucan (CSBG) alters the maturation of dendritic cells (DCs). DC phenotypes were analyzed using FACScan. The expression of surface molecules, including major histocompatibility complex (MHC) classes I and II, as well as CD80 and CD86, increased on DCs that were stimulated with lipopolysaccaride (DCs/LPS), in comparison with unstimulated bone marrow-derived DCs (BM-DCs). Furthermore, the level of surface molecule expression on DCs stimulated with CSBG (DCs/CSBG) was between that of DCs and DCs/LPS. Phagocytosis was assessed by the uptake of FITC-dextran. There were no differences in the uptake of dextran among DCs/LPS and DCs/CSBG. The ability of BM-DCs to uptake dextran was higher than that of DCs/LPS and DCs/CSBG. We analyzed the concentration of IL-12 secreted by DCs using ELISA. BM-DCs secreted a low concentration of IL-12, while DCs/LPS and DCs/CSBG secreted higher levels of IL-12 than BM-DCs. There were no remarkable differences in the concentrations of IL-12 produced by DCs/LPS and DCs/CSBG. This data suggests that CSBG may augment DC maturation.
