ABSTRACT
Objective:
To investigate the effect of compound polysaccharide with Lentinan,Pachymaran and Tremella polysaccharide on the function of macrophages under various treatment conditions.Methods:
The macrophage strain RAW264.7 cells were treated with compound polysaccharide (CP),compound polysaccharide combined with LPS (CP + LPS) and pre-treated with compound polysaccharide and then combined with LPS (Pre-CP + LPS).RAW264.7 cell endocytosis of Rhodamine NP (RNP) was detected by fluorescence microscopy and flow cytometry.The level of NO was detected by Griess reagent.The expression levels of CD40,CD80 and CD86 were detected by flow cytometry.Results:
Compound polysaccharides treatment can enhance the phagocytosis of RAW264.7 cells on fluorescent microspheres with time-dependent manner.The compound polysaccharide could promote the secretion of NO in RAW264.7 cells when the concentration was above 1 000 μg/ml.Compound polysaccharide could improve the expression levels of CD40,CD80 and CD86 in RAW264.7 cells.Under the condition of LPS stimulation,both co-treatment and pre-treatment with compound polysaccharide could reduce the expression levels of CD40,CD80 and CD86 in RAW264.7 cells.Conclusion:
CP can regulate the immune function of RAW264.7 cells under various treatment conditions that it promotes activation and phagocytosis of the resting state cells and inhibits activation of LPS treated cells.
