摘要: 摘要:目的观察同种异基因小鼠皮肤移植急性排斥对受体小鼠胸腺细胞亚群组成的影响。方法以BALB / c 小 鼠作为供体,C57BL /6 为受体,建立小鼠同种异基因皮肤移植模型,于术后第7 天拆线,第10 天取胸腺,制备胸腺单 细胞悬液,通过流式细胞仪检测胸腺细胞各个亚群的比例。结果与对照组相比,同种异基因皮肤移植小鼠胸腺 明显萎缩,胸腺细胞总数明显减少,胸腺细胞亚群细胞数量显著降低,同时,调节性T 细胞及胸腺细胞发育和迁出 不同阶段细胞绝对数均减少。结论皮肤移植排斥反应明显抑制受体小鼠胸腺及胸腺细胞的发育。该研究结果 提示,急性移植排斥反应对中枢免疫器官胸腺中的T 细胞发育分化具有重要影响。

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.

Key words: skin allograft, mice, rejection, thymocytes
