摘要:

背景:体外小鼠颅盖骨实验已证实了其结核杆菌热休克蛋白10的破骨效应。
目的:在诱导破骨细胞分化的体外细胞培养系统中,研究重组结核杆菌热休克蛋白10对破骨细胞分化的影响及相关机制。
方法:选用人巨噬细胞集落刺激因子依赖性附着性血液单个核细胞,实验分为:核因子κB受体活化因子配体+重组结核杆菌热休克蛋白10组、核因子κB受体活化因子配体组、重组结核杆菌热休克蛋白10组(1 mg/L)、阴性对照组(完全培养基),核因子κB受体活化因子配体+重组结核杆菌热休克蛋白10组、重组结核杆菌热休克蛋白10组中重组结核杆菌热休克蛋白10质量浓度为1 mg/L,在含有巨噬细胞集落刺激因子的a-MEM培养液重悬单核细胞,各组培养7,14,21 d后,观察所形成的抗酒石酸酸性磷酸酶阳性染色多核细胞的形态、数目、骨吸收面积;各组NFATc1、c-Fos基因及蛋白表达情况。
结果与结论:阴性对照组无抗酒石酸酸性磷酸酶阳性多核破骨细胞分化生成,其余各组均有抗酒石酸酸性磷酸酶阳性多核破骨细胞分化生成,并在小牛骨磨片上形成吸收陷窝;重组结核杆菌热休克蛋白10组形成的破骨细胞分化细胞数目、吸收陷窝数目及陷窝面积显著低于核因子κB受体活化因子配体+重组结核杆菌热休克蛋白10组;阴性对照组 NFATc1、c-Fos基因表达水平显著低于核因子κB受体活化因子配体+重组结核杆菌热休克蛋白10组和重组结核杆菌热休克蛋白10组,而重组结核杆菌热休克蛋白10组表达NFATc1、c-Fos蛋白,显著低于核因子κB受体活化因子配体+重组结核杆菌热休克蛋白10组。提示结核杆菌热休克蛋白10参与破骨细胞分化的形成,可能与诱导相关基因NFATc1、c-Fos表达上调有关。

Abstract:

BACKGROUND: The mycobacterium tuberculosis heat shock protein 10 exerts effects on the osteoclasts by in vitro mouse cranium experiment,
OBJECTIVE: To investigate the effect and mechanism of recombinant mycobacterium tuberculosis heat shock protein 10 (CPN10) on the differentiation of osteoclasts in the in vitro culture system that induces osteoclast differentiation. 
METHODS: Human macrophage colony-stimulating factor-dependent adhesive blood mononuclear cells were divided into four groups: receptor activator for nuclear factor-κB ligand (RANKL)+CPN10 (1 mg/L), RANKL, CPN10 (1 mg/L), and negative control (complete culture medium). Monocytes were resuspended in a-MEM medium containing macrophage colony-stimulating factor, and were cultured in each group for 7, 14, 21 days. The morphology, quantity and bone resorption area of osteoclasts were examined by tartrate-resistant acid phosphatase (TRAP) staining. The expressions of NFATc1 and c-Fos gene and protein were also detected.
RESULTS AND CONCLUSION: In negative control group, no TRAP-positive multinucleated osteoclasts generated, while in the other groups, TRAP-positive multinucleated osteoclasts differentiated and formed the lacunae in the small bone grinding. The number of osteoclasts formation and resorption in CPN10 group were significantly lower than that in RANKL+CPN10 group. The expression of NFATc1 and c-Fos in the negative control group C was significantly lower than that of RANKL+CPN10 group and CPN10 group. However, CPN10 expressed NFATc1 and c-Fos protein, which was significantly lower than RANKL+CPN10 group. CPN10 is involved in the formation of osteoclasts, and the mechanism is related with the upregulation of NFATc1, c-Fos expression.
