Rabbit antiidiotypic IgG directed against IgG F(ab')2 anti-tetanus toxoid (TT) antibodies ("idiotype") elicited a Prausnitz-Kustner reaction in normal skin sites sensitized 48 h earlier with the serum of the idiotype donor that contained IgE anti-TT antibodies. The serum moiety that caused the sensitization was heat sensitive (56 degrees C, 1 h), and was specifically removed by passage over immunosorbents containing rabbit antihuman IgE or TT antigen. The data obtained indicate that human IgG and IgE antibodies share idiotypic determinants and raise the possibility that idiotypic interactions may play a role in the regulation of the IgE antibody response in man.
针对抗破伤风类毒素(TT)抗体的IgG F(ab')2(“独特型”)的兔抗独特型IgG,在48小时前用含有抗TT IgE抗体的独特型供体血清致敏的正常皮肤部位引发了普劳斯尼茨 - 屈斯特纳反应。引起致敏的血清部分对热敏感(56℃,1小时),并且通过与含有兔抗人IgE或TT抗原的免疫吸附剂孵育可特异性去除。所获得的数据表明,人IgG和IgE抗体共享独特型决定簇,并增加了独特型相互作用可能在人类IgE抗体反应调节中起作用的可能性。
