粉防己碱对β-葡聚糖诱导的RAW264.7细胞增殖的作用

Effects of tetrandrine on β-glucan induced RAW264.7 cells proliferation

目的观察粉防己碱对β-葡聚糖诱导的小鼠巨噬细胞(RAW264.7细胞)增殖的作用。方法建立细胞模型。四甲基偶氮唑盐(MTT)法检测不同浓度粉防己碱对RAW264.7细胞增殖的影响,酶联免疫吸附试验(ELISA)测定培养上清液中白细胞介素(IL)-6、肿瘤坏死因子-α(TNF-α)、前列腺素E2(PGE2)、IL-10的水平。结果 MTT法检测结果提示粉防己碱对RAW264.7细胞增殖表现为双相性作用;ELISA结果提示适当浓度的粉防己碱可抑制IL-6、TNF-α、PGE2的表达,同时促进IL-10的表达。结论粉防己碱影响β-葡聚糖诱导的RAW264.7细胞增殖的作用,可能与抑制IL-6、TNF-α、PGE2的表达,同时促进IL-10的表达有关。

Objective To observe effects of tetrandrine on β-glucan induced RAW 264 .7 cells proliferation .Methods RAW 264 .7 cells model was established .Four methyl thiazol tetrazolium（MTT） was used to detect the effects of different concentrations of tetrandrine on the proliferation of RAW264 .7 cells .The levels of interleukin（IL）-6 ,tumor necrosis factor-α（TNF-α） ,prostaglan-din E2 （PGE2 ） and IL-10 in the culture supernatant were measured by enzyme linked immunosorbent assay（ELISA） .Results MTT results showed that the growth curves of different concentrations of tetrandrine on RAW264 .7 cells had biphasic affections .ELISA results suggested that tetrandrine could inhibit the IL-6 ,TNF-α,PGE2 expressions and promote IL-10 expression .Conclusion Effects of tetrandrine onβ-glucan induced RAW264 .7 cells proliferation are relative to inhibition of IL-6 ,TNF-α,PGE2 expressions and promotion of IL-10 expression .
