目的

探讨白介素6(IL-6)、程序性死亡因子配体1(PD-L1)在胃食管反流病(GERD)发生中的作用。

方法

在体外培养大鼠的食管上皮细胞、CD4+T细胞,并建立正常大鼠食管上皮细胞和CD4+T细胞共培体系。实验组培养基依次加入鹅去氧胆酸、胰酶、盐酸溶液,使得培养基pH分别调节为4、5、6,培养12 h、24 h、48 h后分别收集下室细胞和上下室上清。对照组细胞正常培养,不予任何刺激处理。采用ELISA法、Western blot检测各细胞组中IL-6、PD-L1的表达水平。实验数据以

xˉ
±s表示。总体比较采用重复测量方差分析,对于满足球形检验数据无需校正,如需校正采用Greenhouse-Geisser校正。

结果

随着pH浓度的增加、培养时间的延长,IL-6、PD-L1在各细胞中的表达量增高,其中IL-6、PD-L1在上皮细胞和CD4+细胞共培体系中的表达量最高(P<0.05)。

结论

炎症细胞因子IL-6可能促进GERD中PD-L1的表达,在GERD的发生发展中发挥重要作用。

Objective

To investigate the role of Interleukin-6 (IL-6) and Programmed Death Ligand 1 (PD-L1) in the pathogenesis of Gastroesophageal reflux disease (GERD).

Methods

In vitro, culture rat esophageal epithelial cells and CD4+T cells and establish a coculture system with normal rat esophageal epithelial cells and CD4+T cells. In the experimental group, chenodeoxycholic acid, pancreatin, and hydrochloric acid were added to the culture medium in order to adjust the pH of the medium to 4, 5, and 6, respectively; cells were cultured for 12 h, 24 h, and 48 h. The control group cells were cultured normally without any stimulation. ELISA and Western blot were used to detect the expression levels of IL-6 and PD-L1 in each group. The experimental data is expressed as

xˉ
±s. The overall comparison uses repeated measures analysis of variance, and no correction is required to meet the sphericity test If correction is required, Green house-Geisser correction is used.

Results

With the increase of pH concentration and the extension of culture time, the expression levels of IL-6 and PD-L1 in each group were significantly increased (P<0.05); expression levels of IL-6 and PD-L1 in epithelial cells and CD4+ cell co-culture system were reached the highest level (P<0.05).

Conclusion

The inflammatory cytokine IL-6 may promote the expression of PD-L1 in GERD and play an important role in the occurrence and development of GERD.
