Antigen-antibody complexes efficiently inhibit the induction of antibody formation. Using Mishell-Dutton cultures, it can be demonstrated that neither T cells nor their products are required for this inhibition of IgM PFC formation. The blockade is at the level of B cells and cannot be overcome by LPS or TRF. The data demonstrate that cross-linking of antigen- and Fc-receptors by antigen-antibody complexes is a blocking signal for B cells.
抗原-抗体复合物能有效抑制抗体形成的诱导。利用米谢尔-达顿培养法可以证明,这种对IgM形成细胞(PFC)形成的抑制并不需要T细胞及其产物。这种阻断作用发生在B细胞水平,且不能被脂多糖(LPS)或促胸腺细胞生成素(TRF)克服。数据表明,抗原-抗体复合物使抗原受体和Fc受体交联,这是一种针对B细胞的阻断信号。
