摘要:
In certain embodiments, the present invention provides a method of treating an IP-10-related disease in a subject, comprising: (a) administering to the subject a predetermined dosage of an anti-IP-10 antibody; (b) detecting the level of the anti-IP-10 antibody in a sample of the subject; and (c) if the level of the anti-IP-10 antibody from step (b) is below a threshold exposure level, increasing the dosage of the anti-IP-10 antibody in the subject such that the IP-10 related disease in the subject is treated. In certain embodiments, the present invention provides an isolated monoclonal anti-idiotypic antibody, or an antigen binding portion thereof, which binds to the anti-IP-10 antibody MDX-1100.
摘要:
Peptides generated from a random library that are bound by a monoclonal antibody to Chlamydial glycolipid exoantigen (GLXA) and thus mimic this antigen are disclosed. Peptides that correspond to antigen-binding regions of an anti-idiotypic antibody (mAb2) specific for anti-GLXA antibody (Ab1) which act as molecular mimics of GLXA are also disclosed used as immunogens to induce broadly reactive genus-specific anti-chlamydial antibodies. These peptides and immunogenic DNA encoding the mAb2-like peptides, microparticle or nanoparticle formulations and other formulations of these peptides are disclosed as are methods for immunizing subjects to obtain genus-specific anti-chlamydial antibodies and to treat or prevent Chlamydia-associated or induced rheumatoid arthritis.

This invention also provides different uses of the monoclonal antibody 8H9 or its derivative.
摘要:
The present invention concerns a chain reaction of cross-linking antibodies or other binding molecules prior or subsequent to binding to a target, such as a target antigen. The invention further concerns oligomers comprising repeat units of binding molecules, such as antibodies, optionally bound to a target, such as a target antigen. The invention also relates to antibodies and other binding molecules with multiple specificities useful in the methods of the invention, as well as various uses of the oligomers and individual binding molecules present in the oligomers.
摘要:
The invention is directed towards mouse-human chimeric variants of CC49 monoclonal antibodies with minimal murine content. A first aspect of the invention provides CDR variants of humanized monoclonal antibody (HuCC49) in which less than all six (three heavy chain and three light chain) Complementarity Determining Regions (CDRs) of CC49 are present. A second aspect of the invention provides SDR variants of humanized monoclonal antibody (HuCC49) in which only Specificity Determining Regions (SDRs) of at least one CDR from CC49 are present. The invention is also directed towards biotechnological methods of making the variants and therapeutic methods of using the variants.
