文题释义:
基质细胞衍生因子1:又称CXCL12或前B细胞刺激因子,基质细胞衍生因子1α主要在骨髓基质细胞表达,在骨髓内皮细胞及CD34+ CD38+ 造血前体细胞中也有连续表达。基质细胞衍生因子1对造血干/前体细胞、前B 细胞、T细胞、树突状细胞等都能有效地起到趋化作用。
趋化因子受体CXCR4:是趋化因子基质细胞衍生因子1(CXCL12)的特异受体。CXCL12对淋巴细胞有强烈的趋化作用。该受体是用来提取纯化艾滋病毒的几个趋化因子受体之一。现在还不清楚是否出现使用CXCR4的人类免疫缺乏病毒是免疫缺乏的原因还是后果。
摘要
背景:
正畸治疗的疗程长,复诊间隔时间过长,一直是困扰正畸临床医师及患者的一个重要问题,如何加快正畸牙移动是目前研究的难点。
目的:验证能否通过局部注射CXC族细胞因子受体4抑制剂AMD3100获得加速牙移动速率的效果,探索基质细胞衍生因子1/ CXC族细胞因子受体信号轴在牙移动的作用。
方法:选择8-10周龄的大鼠90只,构建正畸牙移动动物模型。将实验分为3组,分别注射基质细胞衍生因子1、CXC族细胞因子受体4抑制剂AMD3100、PBS,均在观察1,3,5,7,10,14 d时分批处死,测量牙移动距离。
结果与结论:①分析测量显示基质细胞衍生因子1组、AMD3100组与PBS组之间牙移动距离有差别,CXC族细胞因子受体4抑制剂AMD3100可在一定程度上加速正畸牙齿的移动,而基质细胞衍生因子1则表现出对牙移动的抑制作用;②实验初步证实了基质细胞衍生因子1/ CXC族细胞因子受体信号轴在正畸牙移动中的重要作用。

Abstract:

BACKGROUND: Orthodontic treatment has a long course and referral interval, which is an important difficulty. How to accelerate orthodontic tooth movement is an issue of concern.
OBJECTIVE: To testify whether the local injection of AMD3100 (CXCR4 antagonist) can accelerate the tooth movement or not, and to explore the role of stromal cell-derived factor 1/CXC chemokine receptor axis in tooth movement.
METHODS: Ninety Sprague-Dawley rats aged 8-10 weeks old were selected and the models of orthodontic tooth movement were established. The model rats were randomized into three groups, and then given the injection of stromal cell-derived factor 1, AMD3100 or PBS. The rats were killed at 1, 3, 5, 7, 10 and 14 days to measure the tooth movement distance.
RESULTS AND CONCLUSION: The tooth movement distance showed difference among three groups; AMD3100 could facilitate the tooth movement, while stromal cell-derived factor 1 exerted inhibitory effect on the tooth movement. To conclude, stromal cell-derived factor 1/CXC chemokine receptor axis plays an important role in tooth movement.
