Abstract
  • A panel of monoclonal antibodies to human IL-1 beta has been used to probe its conformational and functional characteristics. Real time antibody-protein interaction was assessed by surface plasmon resonance with a BIAcore apparatus, in order to determine the kinetic and thermodynamic parameters of the interaction and to map the recognition sites of the antibodies on the IL-1 beta surface. Topological analysis was thus compared to the inhibitory capacity of antibodies for IL-1 beta bioactivity and binding to the activating receptor IL-1RI. This functional mapping analysis allows the following hypothesis. At least two discrete areas of IL-1 beta, located within the sequences 133-147 and 177-186 (as defined by mAbs MhC1 and BRhD2, respectively), are apparently involved in IL-1RI-independent agonist activity, and thus possibly take part in the interaction with the receptor accessory protein IL-1RAcP. Another area in the 133-147 sequence (defined by mAb BRhC3) is involved in agonist binding to its receptor CDw121a (IL-1RI), whereas a site recognized by mAb BRhG5 within the sequence 218-243 is selectively responsible for non-agonist binding to the activating receptor. The loop between the 4th and the 5th beta-strand, at the open end of the IL-1 beta-barrel structure, may possibly take part in both non-agonist binding to IL-1RI and in the interaction with IL-1RAcP.
