本文报道了在缺乏9.3单抗识别抗原的CD_8阳性亚群中,外周血T淋巴细胞中仅能检测到S-100蛋白。用免疫荧光法,用纯化的抗S-100蛋白抗体,对通过淘洗技术获得的高纯度人外周血T细胞亚群进行免疫荧光染色。绝大多数S蛋白(特别是其CD8亚单位)阳性细胞在β阳性、9.3阴性的亚群中被检测到。这一亚群先前已被证明包括所有同种异体抗原特异性和组胺诱导的抑制T细胞。其他T亚群,即使是CD8阳性(但9.3阳性)或9.3阴性(但CD8阴性)的T亚群,通常也是S-100阴性的。免疫电子显微镜证实,胞浆内显示过氧化物酶活性的S-100阳性细胞仅存在于CD8阳性、9.3阴性的亚群中。S-100蛋白在特定的T8抑制亚群细胞中的这一发现扩大了该蛋白的已知分布范围,并可能对其在免疫反应调节中的作用具有重要意义。
SummaryThe present report concerns the demonstration of the exclusive detection among peripheral blood T-lymphocytes of the S-100 protein within the CD8-positive subpopulation wich lacks the antigen recognized by the 9.3 monoclonal antibody. Highly purified human peripheral blood T-cell subsets, obtained by means of panning techniques, were first stained, by an immunofluorescence method, with purified anti-S-100 protein antibodies. The vast majority of S-100 protein- (and, specifically, itsβ subunit) positive cells were detected in the CD8-positive, 9.3-negative subset. This subset had previously been shown to comprise all the alloantigen-specific and histamine-inducible suppressor T-cells. Other T-subsets, even those showing either CD8-positivity (but 9.3-positivity) or 9.3-negativity (but CD8-negativity), were, as a rule, S-100 negative. Immunoelectronmicroscopy confirmed that the S-100-positive cells, showing peroxidase activity within the cytoplasm, were found exclusively within the CD8-positive, 9.3-negative subset. This finding of S-100 protein in cells of a specific T8 suppressor subset extends the range of the known distribution of this protein and may have important implications concerning its role in the modulation of immune responses.
