通过制备抗人T细胞白血病系HPB-ALL细胞的杂交瘤,获得了针对T细胞E玫瑰花结受体的IgM单克隆抗体。这种抗体名为EDN-34 B1,只与T细胞谱系的细胞反应,包括三种T细胞白血病细胞系的细胞。它不与B细胞系细胞、正常B细胞或单核细胞反应。EDN-34 B1识别分子量约为50,000的单一多肽,能够阻断E-玫瑰花结形成,并且其与靶细胞的结合可以被单克隆抗体9.6和OKT-11特异性阻断,这两种抗体都是抗E-受体抗体。EDN-34 B1对正常胸腺细胞和外周T细胞具有100%的细胞毒性,因此能够从混合淋巴细胞群中常规去除这些细胞,并且比Ab 9.6杀死更高百分比的正常T淋巴细胞,尽管免疫荧光研究表明两种抗体结合相同部分的PBL。这种现象可能是由于EDN-34 B1的IgM性质。向PBL中添加EDN-34 B1和补体完全消除了T细胞功能,如MLR中的促分裂原(PHA)刺激和应答,而单独添加EDN-34 B1仅影响MLR。
An IgM monoclonal antibody directed against the T-cell E-rosette receptor was obtained by preparing a hybridoma against cells of a human T-cell leukemia line, HPB-ALL. The antibody, named EDN-34B1, reacts exclusively with cells of T-cell lineage, including those of three T-cell leukemia lines. It does not react with cells of B-cell lines, normal B-cells, or monocytes. EDN-34B1 recognizes a single polypeptide of approximately 50,000 molecular weight, is capable of blocking E-rosette formation, and its binding to the target cell can be specifically blocked by monoclonal antibodies 9.6 and OKT-11, both anti-E-receptor antibodies. EDN-34B1 is 100% cytotoxic against normal thymocytes and peripheral T-cells, thus enabling the routine removal of such cells from a mixed lymphocyte population, and kills a higher percentage of normal T-lymphocytes than Ab 9.6, even though immunofluorescence studies have shown that both antibodies bind to the same fraction of PBLs. This phenomenon may be due to the IgM nature of EDN-34B1. Addition of EDN-34B1 and complement to PBLs totally abrogates T-cell functions such as mitogen (PHA) stimulation and response in MLR, while addition of EDN-34B1 alone only affects MLR.
