B-Cell Receptor (IMAGE) Max-Planck-Gesellschaft Caption On resting B-cells, the B-cell receptor forms oligomers from several subunits. The receptors are inactive in this form. The binding of the receptor to a matching binding partner (antigen) results in the dissolution of this oligomer structure and activates the signalling chains in the cell interior (flashes).
