Abstract: An IL-1? binding molecule, in particular an antibody to human IL-1?, especially a human antibody to human IL-1? is provided, wherein the CDRs of the heavy and light chains have amino acid sequences as defined, for use in the treatment of an IL-1 mediated disease or disorder, e.g. osteoarthritis, osteroporosis and other inflammatory arthritides.

Abstract: The invention provides monoclonal antibodies (Mabs) which are cross-protective against endotoxemia caused by at least two different Gram-negative bacterial strains having different core structures; and methods of production of these antibodies. By use of the Kohler/Milstein procedure involving immunization of mice with a number of different rough strains of heat-killed Gram-negative bacteria, followed by fusion and proper screening of the resulting hybridomas, such murine MAbs are obtained. The murine MAbs may be chimerized or humanized by known methods.
