Fibrin and D-dimer bind to monomeric GPVI.
Fibrin has recently been shown to activate platelets through the immunoglobulin receptor glycoprotein VI (GPVI). In the present study, we show that spreading of human platelets on fibrin is abolished in patients deficient in GPVI, confirming that fibrin activates human platelets through the immunoglobulin receptor. Using a series of proteolytic fragments, we show that D-dimer, but not the E fra...
متن کاملPlatelet collagen receptor Glycoprotein VI‐dimer recognizes fibrinogen and fibrin through their D‐domains, contributing to platelet adhesion and activation during thrombus formation
Essentials Glycoprotein VI (GPVI) binds collagen, starting thrombogenesis, and fibrin, stabilizing thrombi. GPVI-dimers, not monomers, recognize immobilized fibrinogen and fibrin through their D-domains. Collagen, D-fragment and D-dimer may share a common or proximate binding site(s) on GPVI-dimer. GPVI-dimer-fibrin interaction supports spreading, activation and adhesion involving αIIbβ3. SUM...
متن کاملFibrin D-dimer: a useful clinical marker of thrombogenesis?
Thrombus formation (thrombogenesis) is a process involving platelet adherence to the vessel wall (sometimes at sites of endothelial injury), platelet aggregation and release, thrombin generation and fibrin formation. In addition, it is also well recognized that the process of atherosclerosis is closely related to ongoing formation and organization of mural thrombi [ l , 21. Improved biochemical...
متن کاملRole of fibrin D-dimer testing in emergency medicine.
OBJECTIVES Systemic values of the fibrinolytic plasma marker fibrin D-dimer are raised in a variety of acute clinical conditions. D-dimer values can now be rapidly determined and used to aid diagnosis in emergency medicine. However, despite clinical guidelines, inappropriate and unnecessary measurement of D-dimer values is a significant clinical problem. An understanding of the pathophysiologic...
متن کاملGenetic predictors of fibrin D-dimer levels in healthy adults.
BACKGROUND Fibrin fragment D-dimer, one of several peptides produced when crosslinked fibrin is degraded by plasmin, is the most widely used clinical marker of activated blood coagulation. To identity genetic loci influencing D-dimer levels, we performed the first large-scale, genome-wide association search. METHODS AND RESULTS A genome-wide investigation of the genomic correlates of plasma D...
