目的
2
建立小鼠小肠上皮间淋巴细胞(IELs)分离及分析方法。
方法
2
小鼠麻醉后分离小肠组织,利用不同浓度的Percoll分离液获得IELs悬液;通过不同荧光抗体标记(CD45、CD3、TCRαβ、TCRγδ、CD8αβ、CD8αα)及流式细胞术检测各细胞亚群,分析小肠IELs数量及其不同亚群比例。
结果
2
通过上述方法,成功分离了小鼠IELs。流式细胞术检测结果显示,CD45
+
CD3

+
IELs占(32.3±1.7)%、TCRαβ
+
CD8αα
+
IELs占(10.8±2.3)%、TCRγδ
+

结论
2
本研究成功建立了小鼠IELs的分离和分析方法,为后续相关研究奠定了技术基础。
Objective
2
To establish the isolation and analysis methods of intestinal intraepithelial lymphocytes (IELs) in mice.
Methods
2
After the mice were anesthetized, the small intestinal tissues were isolated, and IELs suspensions were prepared using Percoll separation solutions of different concentrations.The cell subsets were detected by labeling with different fluorescent antibodies (CD45, CD3, TCRαβ, TCRγδ, CD8αβ, CD8αα) combined with flow cytometry, so as to determine the number of small intestinal IELs and the proportions of their different subsets.
Results
2
By the aforementioned method, IELs of mice were successfully isolated. Flow cytometry analysis revealed that CD45⁺CD3⁺IELs accounted for (16.4±1.4)% of the total lymphocytes. Among small intestinal IELs, the proportions of cell subsets were as follows:TCRαβ
+
IELs (32.3±1.7)%,TCRγδ
+
IELs (64.0±2.3)%,TCRαβ
+
CD8αα
+
IELs (10.8±2.3)%,and TCRαβ
+
CD8αβ
+
IELs (13.4±1.9)%.
Conclusion
2
This study successfully establishes the isolation and analysis methods of mouse IELs, thereby laying a technical foundation for subsequent relevant research.
