本试验旨在研究苜蓿素对脂多糖(LPS)刺激下体外培养奶牛乳腺上皮细胞活性和炎症相关基因表达的影响。将体外培养的奶牛乳腺上皮细胞分成6组,对照组采用基础培养基,试验组在基础培养基中分别加入1μg/m L LPS(L组)、1μg/m L LPS和2.5μg...本试验旨在研究苜蓿素对脂多糖(LPS)刺激下体外培养奶牛乳腺上皮细胞活性和炎症相关基因表达的影响。将体外培养的奶牛乳腺上皮细胞分成6组,对照组采用基础培养基,试验组在基础培养基中分别加入1μg/m L LPS(L组)、1μg/m L LPS和2.5μg/m L苜蓿素(L+2.5组)、1μg/m L LPS和5.0μg/m L苜蓿素(L+5组)、1μg/m L LPS和10.0μg/m L苜蓿素(L+10组)以及1μg/m L LPS和15.0μg/m L苜蓿素(L+15组),培养24 h。结果表明:1)与对照组相比,L组奶牛乳腺上皮细胞相对增殖率极显著降低(P<0.01),而L+2.5组和L+10组则极显著升高(P<0.01);2)与L组相比,L+10组和L+15组细胞超氧化物歧化酶活性显著升高(P<0.05),而乳酸脱氢酶活性和一氧化氮浓度显著降低(P<0.05);3)与L组相比,L+5组和L+10组细胞的白细胞介素8、白细胞介素1β、肿瘤坏死因子α、Toll样受体2和Toll样受体4的相对表达量均极显著降低(P<0.01),L+5组细胞的髓样分化因子88相对表达量均显著降低(P<0.05)。结果提示,在LPS刺激下,添加苜蓿素能够提高奶牛乳腺上皮细胞活性和抗氧化性能,抑制炎症相关基因的表达,发挥抗炎作用。展开更多
