Abstract During rheumatoid arthritis there is enlargement and increased cellularity of the synovial lining of joints before invasion by the synovium of the underlying cartilage and bone. This increased tissue mass requires a network of blood vessels to supply nutrients and oxygen. Disruption of synovial angiogenesis is thus a desirable aim of antiarthritic therapies. Protease-activated kringles 1-5 K1-5 is an angiogenesis inhibitor related to angiostatin. In common with angiostatin K1-5 contains the first four kringle domains of plasminogen but also encompasses the kringle 5 domain which confers enhanced antiangiogenic activity when compared with angiostatin. The purpose of the present study was to assess the effect on murine arthritis of K1-5. Arthritis was induced in DBA 1 mice by a single injection of bovine collagen. .
