目的
2
探讨苓桂术甘汤调控miR-140-5p/Toll样受体4(toll like receptor 4,TLR4)/核转录因子-κB(nuclear factor-kappa B,NF-κB)信号通路对溃疡性结肠炎(ulcerative colitis,UC)大鼠肠黏膜屏障及免疫平衡的影响。
方法
2
取SD大鼠用2,4,6-三硝基苯磺酸(2
4
6-trinitrobenzenesulfonic acid solution,TNBS)诱导建立UC模型,随机分为5组:模型组、苓桂术甘汤低剂量组、苓桂术甘汤高剂量组、NC-miR-140-5p(miR-140-5p阴性对照)组、苓桂术甘汤高剂量组+miR-140-5p antagomir(miR-140-5p抑制剂)组,每组10只,另取10只大鼠作对照组,分组干预后检测大鼠结肠黏膜损伤指数(colonic mucosal injury index,CMDI)评分与结肠长度;透射电镜观察各组大鼠结肠黏膜屏障超微结构;流式细胞实验检测各组大鼠外周血Treg、Th17细胞比例及Treg/Th17比值;ELISA检测大鼠血清免疫炎症相关因子白细胞介素(interleukin,IL)-6、IL-17、IL-10、转化生长因子β1(transforming growth factor-β1,TGF-β1)水平;采用实时荧光PCR及免疫印迹法检测大鼠结肠黏膜组织miR-140-5p/TLR4/NF-κB信号相关因子表达。
结果
2
与对照组比较,模型组大鼠结肠黏膜屏障超微结构损伤严重,CMDI、Th17细胞比例、血清IL-6与IL-17水平、结肠黏膜组织TLR4 mRNA、蛋白表达与p-NF-κB p65/NF-κB p65显著升高(
P
<
0.05),结肠长度、Treg细胞比例、Treg/Th17比值、血清IL-10与TGF-β1水平、结肠黏膜组织claudin-1、claudin-4蛋白表达与miR-140-5p表达显著降低(
P
<
0.05)。与模型组比较,苓桂术甘汤低剂量组、苓桂术甘汤高剂量组大鼠结肠黏膜屏障超微结构损伤均减轻,CMDI、Th17细胞比例、血清IL-6与IL-17水平、结肠黏膜组织TLR4 mRNA、蛋白表达与p-NF-κB p65/NF-κB p65均降低(
P
<
0.05),结肠长度、Treg细胞比例、Treg/Th17比值、血清IL-10与TGF-β1水平、结肠黏膜组织claudin-1、claudin-4蛋白表达与miR-140-5p表达均升高(
P
<
0.05);NC-miR-140-5p组大鼠各指标差异无统计学意义(
P
>
0.05);高剂量苓桂术甘汤作用更强。下调miR-140-5p可减弱高剂量苓桂术甘汤对UC模型大鼠各指标的作用。
结论
2
苓桂术甘汤可通过上调miR-140-5p而抑制TLR4/NF-κB信号激活,进而促使Treg/Th17免疫平衡向Treg偏移,抑制免疫炎症,减轻UC大鼠肠黏膜屏障损伤。
Objective
2
To investigate the effect of Linggui Zhugan decoction on intestinal mucosal barrier and immune balance in rats with ulcerative colitis(UC) by regulating the miR-140-5p/Toll like receptor 4(TLR4)/nuclear factor-kappa B(NF-κB) signaling pathway.
Methods
2
Sprague-Dawley rats were induced with 2,4,6-trinitrobenzene sulfonic acid to establish a model of UC,and then the rats were randomly divided into model group,low-dose Linggui Zhugan decoction group,high-dose Linggui Zhugan decoction group,NC-miR-140-5p(miR-140-5p negative control) group,and high-dose Linggui Zhugan decoction group+miR-140-5p antagonist(miR-140-5p inhibitor) group,with 10 rats in each group. Another 10 rats were selected as control group. After grouping and intervention,colonic mucosal injury index(CMDI) score and colon length were measured for each group; transmission electron microscopy was used to observe the ultrastructure of intestinal mucosal barrier;flow cytometry was used to measure the percentages of Treg and Th17 cells in peripheral blood and Treg/Th17 ratio;ELISA was used to measure the serum levels of immune inflammatory factors such as interleukin-6(IL-6),interleukin-17(IL-17),interleukin-10(IL-10),and transforming growth factor-β1(TGF-β1) in rats; quantitative real-time PCR and Western blotting were used to measure the expression of the factors associated with the miR-140-5p/TLR4/NF-κB signaling pathway in the colonic mucosal tissue of rats.
Results
2
Compared with the control group,the model group had severe damage of the ultrastructure of colonic mucosal barrier and significant increases in CMDI,the percentage of Th17 cells,the serum levels of IL-6 and IL-17,the mRNA and protein expression levels of TLR4 in colonic mucosal tissue,and p-NF-κB p65/NF-κB p65(
P
<
0.05),as well as significant reductions in colon length,the percentage of Treg cells,Treg/Th17 ratio,the serum levels of IL-10 and TGF-β1,the protein expression levels of claudin-1 and claudin-4,and the expression of miR-140-5p in colonic mucosal tissue(
P
<
0.05). Compared with the model group,the low- and high-dose Linggui Zhugan decoction groups had alleviation of the damaged ultrastructure of colonic mucosal barrier and significant reductions in CMDI,the percentage of Th17 cells,the serum levels of IL-6 and IL-17,the mRNA and protein expression levels of TLR4 in colonic mucosal tissue,and p-NF-κB p65/NF-κB p65(
P
<
0.05),as well as significant increases in colon length,the percentage of Treg
cells,Treg/Th17 ratio,the serum levels of IL-10 and TGF-β1,the protein expression levels of claudin-1 and claudin-4,and the expression of miR-140-5p in colonic mucosal tissue(
P
<
0.05). The NC-miR-140-5p group had no significant changes in these indicators(
P
>
0.05),and high-dose Linggui Zhugan decoction had a stronger effect. Downregulation of miR-140-5p could weaken the effect of high-dose Linggui Zhugan decoction on various indicators in a rat model of UC.
Conclusion
2
Linggui Zhugan decoction can inhibit TLR4/NF-κB signal activation by upregulating miR-140-5p,thereby promoting the shift of Treg/Th17 immune balance to Treg,inhibiting immune inflammation,and alleviating intestinal mucosal barrier damage in UC rats.
