Monoclonal antibodies reactive with fibrin(ogen) degradation products generated by matrix metalloproteinases

摘要

The invention provides monoclonal antibodies which are reactive with fibrin(ogen) degradation products (FDPS) generated by matrix metalloproteinases (MMPs), such as MMP-3, MMP-7, and membrane-type 1, MT1-MMP proteolysis of fibrinogen and cross-linked fibrin (and not plasmin or other proteases). Monoclonal antibodies of the invention include, but are not limited to, H5, F2, 90/2, 90/5, B4, 13, C6, A6, G6, E6, 197-1 and 197-2. This invention also provides methods of using monoclonal antibodies for detection of FDPs generated by proteolysis of fibrin(ogen) by MMPs, such as MMP-3, MMP-7, and MT1-MMP. In addition, the present invention provides methods for diagnosing rheumatoid arthritis, osteoarthritis, and synovitides, as well as angiogenesis, atherosclerosis, renal diseases, malignancy and inflammation. The present invention also provides methods for diagnosing fibrin formation and degradation in physiological processes such as in wound healing deficiencies and abnormalities, and in development of human placenta and in pregnancy diseases.
