麻疹患者T淋巴细胞亚群和调节性T淋巴细胞分析

目的 探讨成年人及儿童麻疹患者急性期与恢复期T淋巴细胞及调节性T淋巴细胞表达水平的变化。 方法 成年人及儿童麻疹患者各40例,用流式细胞术分别测定各组出疹期和恢复期患者外周血CD+3总T细胞、CD+4辅助性T细胞(Th)、CD+8细胞毒性T细胞(Tc)及CD+4CD+25调节性T淋巴细胞(Treg)比例。 结果 成年人麻疹患者出疹期较对照期外周血CD+3总T和CD+4Th表达水平降低,CD+4CD+25 Treg表达水平升高,恢复期CD+4Th升高,CD+8Tc降低,CD+4/CD+8比值升高,CD+4CD+25 Treg降低。儿童麻疹患者出疹期较对照组CD+3总T、CD+4Th降低,恢复期较出疹期CD+3总T表达回升。 结论 T淋巴细胞及调节性T淋巴细胞参与成年人及儿童麻疹患者免疫状态的调节,但其表达水平在成年人和儿童中有差异。

Expression of T lymphocyte and regulatory T lymphocyte in patients with measles

Objective To understand the changes in T lymphocyte and regulatory T lymphocyte expression in adults and children infected with measles in acute and convalescence periods.Methods Forty adults infected with measles and 40 children infected with measles were selected.The proportions of CD+3T cell,CD+4helper T lymphocyte(Th),CD+8cytotoxic T lymphocyte(Tc) and CD+4CD+25 regulatory T lymphocyte(Treg) in their peripheral blood in acute and convalescence periods were determined with flow cytometry assay.Results In...
