摘要
目的研究帕金森病(PD)患者外周血淋巴细胞亚群的变化,并探讨其在疾病进程中的意义。方法选取典型的原发性PD患者34例及健康对照35名,采用流式细胞术检测外周血淋巴细胞中纯真(naive)、记忆(memory)及调节性(regulatory)T细胞亚群百分比,比较两组间各T细胞亚群的差异。结果与对照组比较,PD患者外周血T淋巴细胞中杀伤性纯真T细胞亚群(CD8+CD45RA+CD45RO-)百分比明显增高(P<0.01),杀伤性记忆T细胞亚群(CD8+CD45RA-CD45RO+)和调节性T细胞亚群(CD4+CD25+FoxP3+)百分比均明显降低(P<0.01),而辅助性纯真T细胞亚群(CD4+CD45RA+CD45RO-)和辅助性记忆T细胞亚群(CD4+CD45RA-CD45RO+)与健康者比较无统计学差异。结论 PD患者外周血淋巴细胞中杀伤性纯真T细胞亚群、杀伤性记忆T细胞亚群及调节性T细胞亚群百分比与健康者间存在统计学差异,细胞免疫失衡可能参与了PD的病理进程。
