摘要
目的:检测乙肝疫苗无应答者外周血Treg细胞的PD-1表达情况及PD-1在Treg中发挥的作用。方法:用流式细胞术检测乙肝疫苗无应答者外周血Treg细胞的PD-1表达情况。结果:乙肝疫苗无应答者外周血Treg细胞的PD-1表达率为(48.7±2.9)%,显著高于乙肝疫苗应答者外周血Treg细胞的PD-1表达率(16.3±1.4)%。结论:乙肝疫苗无应答者外周血Treg细胞的PD-1表达率的显著上调,有可能参与了Treg的抑制机制。
Objective:To detect the PD-1 expression in the regulatory T cells of non-responders after hepatitis B surface antigen vaccine immunization, as to understand the role of PD-1 in the Tfeg.Methods: The PD-1 expression in the regulatory T cells of non-re- sponders was detected by FCM.Results: The frequency of Treg expressing PD-1 in the peripheral blood mononuclear cells (PBMCs) of non-respondcr subjects (NR) was (48.7%±2.9%).In high-responder subjects (HR),the frequency of PBMC Treg expression of PD-1 was (16.3%±1.4 %). Conclusion'The expression of PD-I is up-regulated in non-respondcrs after hepatitis B surface antigen vaccine immunization, which might be involved in the role of Treg.
