WebCovalent incorporation (cross-linking) of plasmin inhibitor α 2 -antiplasmin (α 2 -AP) into fibrin clots increases their resistance to fibrinolysis. We hypothesized that α 2 -AP may also interact noncovalently with fibrin prior to its covalent cross-linking. WebMetformin reduces fibrin cross-linking and therefore, ultimately, reduces the risk of thrombosis (14). In summary, with regards to glycation, metformin has a dual effect. It lowers blood glucose, (a well-known and established activity) plus, as new research is revealing, it is an effective inhibitor of cross-linking through carbonyl trapping. WebJul 9, 2007 · FXIIIa-induced fibrin cross-linking. Cross-linking can produce some changes in clot structure, particularly at higher concentrations of FXIII . However, cross-linking appears to enhance clot rigidity and decrease inelastic deformation primarily by stabilizing the interactions between preassembled protofibrils.
