Adult T-cell leukaemia/lymphoma (ATLL) is an aggressive neoplastic disease that usually exhibits a CD4(+)CD25(+) phenotype. Regulatory T cells (Treg), which suppress T-cell effector function, are characterized by the co-expression of CD4 and CD25. We analysed the expression of forkhead/winged helix transcription factor (FoxP3), a specific marker that is important for the function of Treg, on ATLL cells from 17 patients (peripheral blood, n = 8; lymph node, n = 9). Real-time polymerase chain reaction and immunostaining detected FoxP3 expression in 10 ATLL cases, but was relatively down-regulated compared with Treg from normal subjects. These results indicate the association of ATLL and Treg.
成人T细胞白血病/淋巴瘤(ATLL)是一种侵袭性肿瘤疾病,通常表现为CD4(+)CD25(+)表型。调节性T细胞(Treg)可抑制T细胞效应功能,其特征为CD4和CD25的共表达。我们分析了叉头/翼状螺旋转录因子(FoxP3)在17例患者的ATLL细胞(外周血,n = 8;淋巴结,n = 9)中的表达,FoxP3是对Treg功能很重要的一种特异性标志物。实时聚合酶链反应和免疫染色在10例ATLL病例中检测到FoxP3表达,但与正常受试者的Treg相比相对下调。这些结果表明ATLL与Treg有关联。
