The effects of IgG1 and IgG2 anti-hapten antibodies waere studied on celluar and humoral reactions induced by immunization with a hapten-carrier complex. IgG2 was shown to depress delayed hypersensitivity reactions to the carrier and to enhance anaphylactic reactions to both the hapten and the carrier whereas IgG1 appeared to have no activity except a little enhancing effect on antibody synthesis to the carrier. The regulatory role of IgG2 antibodies, which were cytophilic for macrophages, in the immune response to a hapten-carrier conjugate is discussed.
研究了IgG1和IgG2抗半抗原抗体对用半抗原-载体复合物免疫诱导的细胞和体液反应的影响。结果表明,IgG2可抑制对载体的迟发型超敏反应,并增强对半抗原和载体的过敏反应,而IgG1除了对载体抗体合成有轻微增强作用外似乎没有活性。本文讨论了对巨噬细胞具有嗜细胞性的IgG2抗体在对半抗原-载体偶联物免疫反应中的调节作用。
