摘要 目的探讨白细胞介素23(IL-23)对人甲状腺上皮细胞增殖、凋亡的影响。方法用(10、50、100)ng/m L IL-23处理Nthy-ori 3-1甲状腺上皮细胞24 h后,用MTT法检测细胞增殖能力改变,藻红蛋白标记的膜联素Ⅴ/7-氨基放线菌素D(annexinⅤ-PE/7-AAD)双标记结合流式细胞术检测细胞凋亡水平变化,Western blot法检测磷酸化的蛋白激酶B(p-AKT)、磷脂酰肌醇3激酶(PI3K)、Bcl-2、Bcl-x L、活化caspase-3蛋白的水平。结果与对照组相比,随着IL-23剂量增加,甲状腺上皮细胞的增殖能力逐渐下降;IL-23下调PI3K/AKT信号蛋白的磷酸化水平并促进甲状腺上皮细胞凋亡。结论 IL-23通过调节PI3K/AKT途径促进甲状腺上皮细胞凋亡。
