A generation ago, the immunoglobulin intramolecular signaling, or allosteric, hypothesis was abandoned in favor of the associative hypothesis, which posited that Fc receptor crosslinking produced the increased affinity of antigen-antibody complexes. This essay argues that there is sufficient evidence to resuscitate the allosteric hypothesis, at least for some antibodies.
一代人以前,免疫球蛋白分子内信号传导或变构假说被摒弃,转而支持结合假说,该假说认为Fc受体交联产生了抗原-抗体复合物亲和力的增加。本文认为,至少对于某些抗体而言,有足够的证据来复兴变构假说。
