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.
