目的本实验设计合成靶向核因子KB(NF-KB)的哑铃形圈套寡核苷酸(ODNs),并验证其对白介素10(IL-10)的作用。方法以阳离子脂质体为载体,将圈套ODNs转染大鼠pMФ细胞6h后用LPS(μg/ml)刺激,用ELISA法及RT-PCR法测圈套ODNs对IL-10在蛋白及mRNA水平的影响。结果哑铃形圈套ODNs可降低在IL-10mRNA及蛋白水平的表达。结论靶向NF-KB的哑铃形圈套ODNs具有抗IL-10的作用。
Objective: Decoy - ODNs in dumbbell shape with the nuclear sequence similar to NF - kB cis - elements were synthetized in this study. To measure the anti -inflammatory action of decoy -ODNs targeting NF - kB. Methods: With carriers of cationic liposomes, decoy ODNs were transfected into pMqb cells from rats. Then the inhibiting effects of the decoy - ODNs of IL - 10 were analysized. Results Decoy - ODNs could decrease the expression of IL - 10 . Conclusions : Decoy - ODNs targeting nuclear factor - kB can decress the expression of IL - 10 in pMФ ceils.
