Fibronectin dependent macrophage fibrin binding.
Plasma fibronectin has been shown to increase the binding of fibrin monomer to macrophages in vitro. In the present study we began characterization of the mechanism underlying this fibronectin activity. Fragments of fibronectin containing the amino terminus enhanced macrophage fibrin binding to the same extent as intact fibronectin on an equimolar basis. However, fibronectin fragments containin...
متن کاملFibronectin binding to thrombin-stimulated platelets: evidence for fibrin(ogen) independent and dependent pathways.
Plasma fibronectin binds in a specific and saturable manner to thrombin-stimulated platelets. gamma-Thrombin stimulated 80% as much fibronectin binding to platelets as alpha-thrombin with conversion of less than or equal to 1% of platelet fibrinogen to fibrin. Afibrinogenemic and normal platelets bound similar quantities of fibronectin in the presence of calcium or magnesium-ethylene glycol tet...
متن کاملFibronectin and fibrin gel structure.
Plasma fibronectin is covalently incorporated into alpha-chains of fibrin gels in the presence of Factor XIII activated by thrombin (FXIIIaT) but not by Factor XIII activated by the snake venom enzyme batroxobin (FXIIIaB). FXIIIaB catalyzes introduction of gamma-gamma cross-links in fibrin but cross-linked alpha-chains are not formed. In the presence of FXIIIaT, fibrin gels formed by batroxobin...
متن کاملRecombinant carboxyl-terminal fibrin-binding domain of human fibronectin expressed in mouse L cells.
The carboxyl-terminal fibrin-binding domain, Fib2, of human fibronectin was expressed in mouse L cells as a fusion protein with the signal sequence of human protein C inhibitor. The recombinant Fib2 (rFib2) protein synthesized by transfected cells retained the ability to form dimers with each other or with mouse fibronectin subunits and was secreted to the medium after extensive glycosylation. ...
متن کاملThe biological effects of fibrin-binding synthetic oligopeptides derived from fibronectin on osteoblast-like cells
PURPOSE The aim of this study was to investigate the effects of synthetic fibronectin (FN) fragments, including fibrin binding sites from amino-terminal FN fragments containing type I repeats 1 to 5, on osteoblast-like cell activity. METHODS Oligopeptides ranging from 9 to 20 amino acids, designated FF1, FF3, and FF5, were synthesized by a solid-phase peptide synthesizing system, and we inves...
