PROBLEM TO BE SOLVED: To provide an anti-IL-6 / IL-6R antibody and a method of using them. The present invention relates to a membrane-bound human interleukin-6 (“IL-6”) when complexed with a human IL-6 receptor (ie, human IL-6 / IL-6R complex (“IL-”. Provided are monoclonal antibodies such as fully human monoclonal antibodies that recognize 6Rc ") (ie IL-6Rc expressed on the cell surface or in soluble form). The antibodies of the invention are the JAK / STAT pathway and the MAPK cascade. IL-6R intracellular signaling can be modulated, eg, blocking, inhibiting, reducing, antagonizing, neutralizing, or interfering with IL-6R intracellular signaling through activation of. Antibodies of the invention are also antibodies that bind soluble IL-6Rc. Also included. Further, the antibodies of the invention also include antibodies that bind to IL-6Rc, where they also bind to human IL-6R alone (ie, if not complexed with IL-6).
