Peripheral blood cells from six patients with acute infectious mononucleosis were studied by two-colour immunofluorescence using antibodies to human T cells, inducer and suppressor-cytotoxic T cell subsets and Ia-like antigens. The absolute number of T cells with the suppressor-cytotoxic phenotype was substantially increased in each case; many of these cells also expressed Ia-like antigens and had the morphology of the large atypical cells characteristic of infectious mononucleosis. These activated suppressor T cells of infectious mononucleosis may therefore represent a control mechanism to prevent viral-induced proliferation of B cells.
采用针对人T细胞、诱导性及抑制性-细胞毒性T细胞亚群以及Ia样抗原的抗体,通过双色免疫荧光法对6例急性传染性单核细胞增多症患者的外周血细胞进行了研究。在每例患者中,具有抑制性-细胞毒性表型的T细胞绝对数量均显著增加;其中许多细胞还表达Ia样抗原,并且具有传染性单核细胞增多症特征性的大的非典型细胞形态。因此,传染性单核细胞增多症的这些活化抑制性T细胞可能代表一种控制机制,以防止病毒诱导的B细胞增殖。
