摘要
为探讨手移植患者术后外周血CD3/HLA DR及CD3/CD( 16 +5 6 )的变化和意义 ,提取患者的外周血细胞 ,加入双荧光标记的鼠抗人单克隆抗体CD3/CD ( 16 +5 6 )、CD3/HLA DR ,单荧光标记的鼠抗人单克隆抗体CD2 5 ,流式细胞分析仪测定。结果发现 ,术后 1周内活化T细胞 (CD2 5 + ,CD3+ /HLA DR+ )和静止性T细胞[CD3+ /CD( 16 +5 6 ) -,CD3+ /HLA DA-]明显下降 ,1周后均逐渐恢复至术前水平 ;NK细胞 [CD3-/CD( 16 +5 6 ) + ]术后 1天内显著升高 ,但第 2天直线下降并维持在低水平。提示免疫抑制剂对移植术后的淋巴细胞亚群有明显的影响 ,术后动态测定CD3/HLA DR及CD3/CD( 16 +5 6 )可为异体手移植的免疫学监测提供参考。
To investigate the changes in the activated T-lymphocyte CD3/HLA-DR and CD3/CD(16+56) populations in peripheral blood of the patients with allogeneic hand transplantation, lymphocytes from peripheral blood of the patients at different time points were immunologically labeled with dual color fluoresecent monoclonal antibodies CD3/CD(16+56) and CD3/HLA-DR, mono-color fluoresecent monoclonal antibody CD25. CD25, CD3/CD(16+56), and CD3/HLA-DR were determined with flow cytometry (FCM). The levels of activated T-lymphocyte (CD25 +,CD3 +/HLA-DR + ), silent T-lymphocyte [CD3 +/CD(16+56) -,CD3 +/HLA-DA - ] decreased significantly during the first week after transplantation and then increased gradually to the pre-operafive level. Nature killer cells [CD3 -/CD(16+56) +] increased significantly at the first day after transplantation, then decreased sharply and maintained a lower level. The results suggest that immunosuppressive agents have significantly effects on lymphocyte subsets in allogenaic hand transplanted patients, and dynamic determination of HLA-DR, CD3 /CD(16+56) could be valuable in immunomonitoring after allogeneichand transplantation.
