title: Preparation of monoclonal antibodies against the IL-6 signal transducer, gp130, that can inhibit IL-6-mediated functions.
abstract: mAbs specific to human gp130, a signal transducing component of the IL-6 receptor complex, were prepared by immunizing mice with a previously described recombinant human soluble gp130. Some of the mAbs inhibited the IL-6-induced association of soluble gp130 and soluble IL-6 receptor. Three mAbs (GPX7, GPX22 and GPZ35) were shown to inhibit IL-6-mediated biological responses such as Ig production in a human B cell line and proliferative responses of a human Lennert's lymphoma-derived T cell line, a human myeloma cell line, and a mouse pro-B cell line-derived transfectant expressing human gp130.
