脂多糖刺激RAW264.7和Ana-1形态改变及细胞因子表达的差异

Objective To compare the morphologic change and cytokines expression in RAW264.7 and Ana-1 stimulated by lipopolysaccharide(LPS). Methods RAW264.7 and Ana-1 were cultivated with various concentrations of LPS(0.1 mg/L, 1 mg/L, 10 mg/L, 100 mg/L). MTT was performed to evaluate the proliferation ability of cells. Two kinds of cells were cultivated with 1 mg/L. Then,the concentrations of TNF-α,IL-1β,IL-6,IL-10 in culture medium were detected by ELISA in different times(0 h,4 h,8 h,12 h,24 h). Results The survival rates of RAW264.7 and Ana-1 (162.05±28.14)% and (159.92±20.43)% were significantly higher in 1 mg/L group than those of other groups. When stimulated with 1 mg/L LPS, both RAW264.7 and Ana-1 expressed cytokines in time-dependent manner (increased first and decreased finally). The concentrations of TNF-α and IL-10 in RAW264.7 group were higher than those Ana-1 group in 4 h only. IL-1β and IL-6,however,were in higher concentrations in RAW264.7 group than Ana-1 group all the time. Conclusions When stimulated with 1 mg/L LPS, both RAW264.7 and Ana-1 have higher survival rate. RAW264.7 and Ana-1 have different ability in expressing cytokines after being stimulated by LPS. Therefore,RAW264.7 and Ana-1 have variant response to LPS slightly.
