A reshaped human antibody to the human IL-6R, comprising: (A) an L chain comprising, (1) a human L chain C region, and (2) an L chain V region comprising human L chain framework regions (FRs), and mouse L chain complementary determination regions (CDRs) of a momoclonal antibody to the IL-6 receptor (IL-6R); and (B) an H chain comprising, (1) a human H chain C region, and (2) an H chain V region comprising human H chain FRS, and mouse H chain CDRs of a monoclonal antibody to the IL-6R. Since major portion of the reshaped human antibody is derived from a human antibody and the mouse CDRs which are less immunogenic, the present reshaped human antibody is less immunogenic to human, and therefor is promised for therapeutic uses.

A method of treating a pathological syndrome includes administration of an activated form of ultra-low doses of antibodies to an antigen, wherein said activated form is obtained by repeated consecutive dilution combined with external impact, and the antigen is a substance or a pharmaceutical agent exerting influence upon the mechanisms of formation of this particular pathological syndrome. Pharmaceutical agent for treating a pathological syndrome contains activated form of ultra-low doses of monoclonal, polyclonal or natural antibodies to an antigen, wherein said activated form is prepared by means of repeated consecutive dilution and external treatment, predominantly based on homeopathic technology, and said antigen is a substance or a drug acting as a direct cause of the pathological syndrome or involved in regulation of mechanisms of its formation. At that, activated forms of ultra-low doses of antibodies are raised against antigens of exogenous or endogenous origin, against autologous antigens, fetal antigens; anti-idiotypic antibodies are used too.

The present invention relates to a methodology of producing antibodies that recognize peptides associated with a tumorigenic or disease state, wherein the peptides are displayed in the context of HLA molecules. These antibodies will mimic the specificity of a T cell receptor (TCR) but will have higher binding affinity such that the molecules may be used as therapeutic, diagnostic and research reagents. The method of producing a T-cell receptor mimic of the present invention includes identifying a peptide of interest, wherein the peptide of interest is capable of being presented by an MHC molecule. Then, an immunogen comprising at least one peptide / MHC complex is formed, wherein the peptide of the peptide / MHC complex is the peptide of interest. An effective amount of the immunogen is then administered to a host for eliciting an immune response, and serum collected from the host is assayed to determine if desired antibodies that recognize a three-dimensional presentation of the peptide in the binding groove of the MHC molecule are being produced. The desired antibodies can differentiate the peptide / MHC complex from the MHC molecule alone, the peptide alone, and a complex of MHC and irrelevant peptide. Finally, the desired antibodies are isolated.

The present invention concerns a method for the oxidative refolding of a hepcidin polypeptide to a form that is mature, bioactive and folded as in the native configuration and molecular mass; a method for measuring the level of native, bioactive hepcidin in a vertebrate animal; a method for measuring the level of hepcidin gene expression in a vertebrate animal; and a method for regulating the production of native, bioactive hepcidin in a vertebrate animal in vivo. The present invention also concerns an antibody or fragment thereof that specifically binds to a continuous, discontinuous, and / or conformational epitope of a mature and bioactive hepcidin folded as in the native configuration; and a pharmaceutical composition that includes the antibody or a hepcidin polypeptide and that provides antimicrobial, agonistic, or antagonistic activities in vivo in a vertebrate animal.

These antibodies, and peptide fragments containing these sequences, can be employed in the assays of the invention, which may be carried out in a sandwich format or a competition format.

Problems to be Solved: The present invention provides a simpler and less expensive method for purifying physiologically active proteins, especially antibodies, which can ensure removal of impurities such as DNA contaminants and viruses, and which can minimize a loss of physiologically active proteins. Means for Solving the Problems: A method for removing impurities in a physiologically active protein-containing sample, which comprises the following steps: 1) allowing the physiologically active protein-containing sample to be converted into an aqueous solution of low conductivity at a pH below the isoelectric point of the physiologically active protein; and 2) removing the resulting particles.

The subject invention relates to monoclonal antibodies that have the ability to bolster the function of the GLP-1 receptor and may therefore have utility in the treatment of mammalian metabolic disorders such as, for example, diabetes.
