PI3K-Akt-mTOR信号通路对Foxp3基因表达的影响
[Abstract]:Objective to study the effect of PI3K-Akt-mTOR signaling pathway on Foxp3 gene expression. Methods 60 Kunming mice of SPF grade were randomly divided into two groups: control group (A) and experimental group (group D). After 3 weeks, blood was collected from the heart, EDTA was anticoagulant, spleen was isolated and single cell suspension was prepared under aseptic condition. The levels of CD4 CD25 regulatory T cells (the percentage of CD4 CD25 Treg cells in CD4 T cells) in peripheral blood and spleen of mice were detected by flow cytometry, and the expression of Foxp3mRNA in spleen cells of mice was detected by RT-PCR. Immunohistochemical SP staining was used to observe the expression of p-mTOR protein in the spleen of mice, and the average optical density of p-mTOR protein expression in each experimental group and control group was measured by computer image analysis. Results the expression of Foxp3 mRNA in the spleen of the experimental group was (0.4853 卤0.0574) 0.7886 卤0.1085 卤0.9639 卤0.2015, which was significantly higher than that of the control group A (0.1345 卤0.0271) (P0.05). The average optical density of p-mTOR protein expression in the spleen of the experimental group was (0.2326 卤0.0431) 0.1156 卤0.022 3n 0.0556 卤0.0041, which was significantly lower than that of the control group A (0.4223 卤0.0534) (P0.05). By pearson correlation analysis, the expression of Foxp3mRNA in mouse spleen was negatively correlated with the expression of p-mTOR protein. Conclusion inhibition of PI3K-Akt-mTOR signaling pathway can increase the expression of Foxp3, and the activation of PI3K-Akt-mTOR signaling pathway is negatively correlated with the expression of Foxp3.
