Blocking B-cell activating factor (BAFF), an important soluble factor for B-cell responses, with specific antibodies is approved for treating autoimmune disorders. Here the authors show, with structural data, that antibody-BAFF interactions not only interrupt BAFF–receptor-binding, but also induce the formation of a less active BAFF polymer.
