Abstract: The present invention relates to the isolation and identification of novel baboon nucleic acid molecules and proteins and polypeptides encoded by such nucleic acid molecules, or degenerate variants thereof, which proteins and polypeptides comprise novel baboon thrombin-activatable fibrinolysis inhibitors or “TAFI” enzyme molecules. Because the novel baboon TAFI proteins and polypeptides of the invention inhibit the breakdown of blood clots, they may be therapeutically useful for the treatment of blood disorders wherein clotting needs to be regulated or promoted, such as hemophilia or von Willebrand's disease or in other situations, such as trauma, wherein blood clotting or coagulation needs to be regulated or promoted. The sequences of the invention are also useful in screening methods for the identification of compounds that modulate the expression of the baboon TAFI nucleic acids and/or the activity of the baboon TAFI proteins and polypeptides of the invention.

Abstract: A new chimeric plasminogen activator with high fibrin affinity was designed to bind to a fibrin clot and initiate clot destruction in the presence of thrombin, but not plasmin. The chimeric molecule has an antibody variable region having a fibrin-specific antigen binding site and a single chain urokinase region having a thrombin activation site but not a plasmin activation site. The preferred embodiment, 59D8-ScuPA-T, has an N-terminal fragment of an anti-fibrin antibody (59DB) and a C-terminal thrombin-activatable low molecular weight single-chain urokinase plasminogen activator (scuPA-T). The scuPA-T portion was obtained by deletion of two amino acids (Phe157 and Lys 158) that make up the plasmin activation site from low molecular weight single chain urokinase-type plasminogen activator (scuPA).

Abstract: The present invention relates to a novel treatment for blood clots within a patient or myocardial infarction which comprises administering a hapten-binding molecule capable of preventing inhibition of plasmin by endogenous alpha-2-antiplasmin. The invention also relates to a treatment for blood clots within a patient or myocardial infarction comprising coadministrating the hapten-binding molecule of the invention together with a thrombolytic agent capable of either dissolving fibrin-platelet clots or inhibiting their formation. The therapy of the invention is capable of increasing clot lysis while minimizing fibrinogen breakdown and preventing the reocclusion of the affected coronary artery. The therapy of the present invention is capable of achieving this goal even in the absence of heparin and when the concentration of thrombolytic agent is lower than that required by other potential therapies.

Abstract: Peptides comprising fibrin-specific epitopic sequences are used to prepare hybridoma cell lines producing antifibrin-specific monoclonal antibodies substantially devoid of fibrinogen-cross-reactivity obtained by somatic cell fusion. The antibodies are useful for the in vivo and in vitro detection of thrombi and fibrin deposits.
