【摘要】 目的:探讨自身免疫调节因子(Aire)基因是否影响调节性T细胞的产生。方法:应用流式细胞术和real-timePCR的方法分别分析了Aire-/-鼠的胸腺细胞和脾脏外周T细胞的CD4+CD25+T细胞分布及Foxp3的表达。结果:与对照鼠相比,Aire-/-鼠的胸腺细胞、脾脏淋巴细胞以及脾脏T细胞总数未发生显著变化;CD4+CD25+调节性T细胞数目以及脾脏T细胞Foxp3mRNA表达无显著差异;成年鼠、3日龄和7日龄鼠的CD4+CD25+T细胞占总的CD4+T细胞的百分比在Aire-/-鼠和相应对照鼠间并无显著差异。结论:结果表明Aire基因不影响CD4+CD25+调节性T细胞的产生。更多还原

【Abstract】 Objective:To clarify the role of Aire on the production of regulatory T cells on mice.Methods:The distribution of CD4~+CD25~+T cells and the expression of Foxp3 mRNA from Aire~ -/- thymus and spleen were separately analyzed using FACS and real-time PCR.Results:Compared with control mice, the total numbers of thymocytes/splenocytes and T cells from Aire~ -/- mice did not show any significant changes; The total CD4~+CD25~+ regulatory T-cell number and Foxp3 mRNA expression did not exhibit any statistically difference; The ratios of CD4~+CD25~+T cells out of CD4~+T cells were similar based on adult /day3/day7 mice analysis.Conclusion:Aire gene does not affect the production of CD4~+CD25~+ regulatory T cells.更多还原
