Abstract

Evidence is presented for the selective suppression of the major idiotypic component of the humoral response to the phenylarsonate hapten by soluble factors derived from T cells (TsF). The existence of TsF with anti-idiotypic receptors was also demonstrated. It was found that TsF with idiotypic and anti-idiotypic receptors coexist in cultures of spleen cells prepared from idiotypically suppressed, hyperimmunized mice. By gel filtration the molecular weight of each factor was found to be 50,000-100,000. Each is sensitive to trypsin and is bound to a column containing anti-H-2a antibodies. Evidence is discussed which suggests the possibility of mutual stimulation of suppressor T cells with idiotypic and anti-idiotypic receptors.

摘要

有证据表明,来自T细胞的可溶性因子(TsF)可选择性抑制针对苯胂酸半抗原的体液反应中的主要独特型成分。还证实了具有抗独特型受体的TsF的存在。研究发现,具有独特型和抗独特型受体的TsF共存于由独特型抑制的、经超免疫的小鼠制备的脾细胞培养物中。通过凝胶过滤发现每个因子的分子量为50,000 - 100,000。每个因子对胰蛋白酶敏感,并与含有抗H - 2a抗体的柱结合。文中讨论了相关证据,这些证据提示了具有独特型和抗独特型受体的抑制性T细胞相互刺激的可能性。
