摘要:目的觀察同種異基因小鼠皮膚移植急性排斥對受體小鼠胸腺細(xì)胞亞群組成的影響。方法以BALB / c 小 鼠作為供體,C57BL /6 為受體,建立小鼠同種異基因皮膚移植模型,于術(shù)后第7 天拆線,第10 天取胸腺,制備胸腺單 細(xì)胞懸液,通過流式細(xì)胞儀檢測胸腺細(xì)胞各個亞群的比例。結(jié)果與對照組相比,同種異基因皮膚移植小鼠胸腺 明顯萎縮,胸腺細(xì)胞總數(shù)明顯減少,胸腺細(xì)胞亞群細(xì)胞數(shù)量顯著降低,同時,調(diào)節(jié)性T 細(xì)胞及胸腺細(xì)胞發(fā)育和遷出 不同階段細(xì)胞絕對數(shù)均減少。結(jié)論皮膚移植排斥反應(yīng)明顯抑制受體小鼠胸腺及胸腺細(xì)胞的發(fā)育。該研究結(jié)果 提示,急性移植排斥反應(yīng)對中樞免疫器官胸腺中的T 細(xì)胞發(fā)育分化具有重要影響。

Abstract: Abstract:Objective To investigate the impacts of allograft rejection on the development of thymocyte subsets in a mouse allogeneic skin transplantation model. Method Skin tissues from BALB / c mice were transplanted into C57BL /6 mice. The total cell number of thymocytes and their subsets in allo-skin-grafted recipients were analyzed by flow cytometry. Result In allo-skin transplantation group,the thymus weight was decreased,the quantities of thymocytes and their subsets including DN,DP,CD4SP and CD8SP cells were significantly decreased compared with the control mice. Conclusion The data showed that the acute rejection significantly impacts the development of T cells in the thymus。
