使用α / β TCR的β链(β F1)和γ / δ TCR的δ链(抗TCR δ -1)特异性单克隆抗体,对57例外周血t细胞淋巴瘤的t细胞受体(TCR)链的细胞表达进行了研究。在39例(69%)中,表型(CD3+ β F1+TCR δ -1-)与大多数正常T细胞相同。在6例(10%)病例中发现第二种模式,即CD3+ β F1-TCR δ -1+表型,DNA分析显示5例病例中δ位点存在克隆重排。这表明,这些病例是肿瘤对应的正常T细胞的小亚群,表达γ δ受体。值得注意的是,这些伽马δ淋巴瘤具有不同寻常的临床病理表现,1例为致死性中线肉芽肿,另外5例为肝脾淋巴瘤,伴脾脏、骨髓和肝脏的窦状/窦状浸润。肿瘤δ细胞在脾红髓中的分布与正常δ细胞的分布相似,这一事实强化了δ T细胞优先归巢到该组织的概念。第三种模式(CD3 +/- β F1-TCR δ 1-)在12例(21%)中被发现,与正常胸腺后T细胞相比,没有发现α - β或γ - δ T细胞受体的证据。
Fifty-seven cases of peripheral T-cell lymphoma were studied for cell expression of the T-cell receptor (TCR) chains, using monoclonal antibodies specific for the beta chain (beta F1) of the alpha/beta TCR, and for the delta chain (anti-TCR delta-1) of the gamma/delta TCR. Three different patterns were demonstrated: in 39 cases (69%), the phenotype (CD3+beta F1+TCR delta-1-) was that of most normal T cells. A second pattern was found on six cases (10%), which were of CD3+beta F1-TCR delta-1+ phenotype, and in which DNA analysis showed a clonal rearrangement of the delta locus in the five cases studied. It is suggested that these cases are the neoplastic counterpart of the small subpopulation of normal T cells that express gamma delta receptor. It is of considerable interest that these gamma delta lymphomas had unusual clinicopathologic presentations, as one case corresponded to a lethal midline granuloma and the five others to hepatosplenic lymphomas with a sinusal/sinusoidal infiltration in spleen, marrow, and liver. The fact that the distribution of the neoplastic gamma delta cells in the splenic red pulp resembles that of normal gamma delta cells reinforces the concept of a preferential homing of gamma delta T cells to this tissue. A third pattern (CD3 +/- beta F1-TCR delta-1-) was seen in 12 cases (21%), in which, by contrast to normal post-thymic T cells, no evidence of either alpha beta or gamma delta T cell receptor was found.
