Aβ delays fibrin clot lysis by altering fibrin structure and attenuating plasminogen binding to fibrin.
Alzheimer disease is characterized by the presence of increased levels of the β-amyloid peptide (Aβ) in the brain parenchyma and cerebral blood vessels. This accumulated Aβ can bind to fibrin(ogen) and render fibrin clots more resistant to degradation. Here, we demonstrate that Aβ(42) specifically binds to fibrin and induces a tighter fibrin network characterized by thinner fibers and increased...

Alzheimer disease is characterized by the presence of increased levels of the amyloid peptide (A ) in the brain parenchyma and cerebral blood vessels. This accumulated A can bind to fibrin(ogen) and render fibrin clots more resistant to degradation. Here, we demonstrate that A 42 specifically binds to fibrin and induces a tighter fibrin network characterized by thinner fibers and increased resi...
متن کاملKinetics of fibrin clot lysis.
The principles relating the lysis times of fibrin clots to their contents of fibrin, plasminogen and plasminogen-activator were investigated. Mathematical considerations suggested that the square of the lysis time should correlate linearly with the fibrin content, and inversely with the activator and the plasminogen contents of the system. Experimental studies, during which these parameters wer...
متن کاملEffects of actin filaments on fibrin clot structure and lysis.
The muscle and cytoskeletal protein actin is released from cells as a consequence of cell death and interacts with components of the hemostatic and fibrinolytic systems, including platelets, plasmin, and fibrin. We report here that incorporation of actin filaments into fibrin clots changes their viscoelastic properties by increasing their shear modulus at low deforming stresses and by nearly el...
متن کاملPolyphosphate enhances fibrin clot structure.
Polyphosphate, a linear polymer of inorganic phosphate, is present in platelet dense granules and is secreted on platelet activation. We recently reported that polyphosphate is a potent hemostatic regulator, serving to activate the contact pathway of blood clotting and accelerate factor V activation. Because polyphosphate did not alter thrombin clotting times, it appeared to exert all its proco...
