Evolution of thrombin formation and fibrinolysis markers, including thrombin-activatable fibrinolysis inhibitor, during severe meningococcemia.
A 17-year-old girl presented with Neisseria meningitidis sepsis, with evidence of disseminated intravascular coagulation. Substitution therapy with both antithrombin and protein C concentrates was initiated, leading to clinical and biological improvement. Sequential dosages were performed for biological markers including thrombin-activatable fibrinolysis inhibitor (TAFI). Substitution therapy w...
متن کاملThrombin activatable fibrinolysis inhibitor.
Thrombin activatable fibrinolysis inhibitor (TAFI) was discovered two decades ago as a consequence of the identification of an unstable carboxypeptidase (CPU), which was formed upon thrombin activation of the respective pro-enzyme (proCPU). The antifibrinolytic function of the activated form (TAFIa, CPU) is directly linked to its capacity to remove C-terminal lysines from the surface of the fib...
متن کاملThrombin-activatable fibrinolysis inhibitor (TAFI) deficient mice.
In order to examine the physiological role of thrombin-activatable fibrinolysis inhibitor (TAFI), we generated homozygous TAFI deficient mice by targeted gene disruption. Intercrossing of heterozygous TAFI mice showed that TAFI mice were born in the expected Mendelian ratio, indicating that transmission of the mutant TAFI allele did not lead to embryonic lethality. TAFI deficient mice developed...

Coagulation and fibrinolysis are processes that form and dissolve fibrin, respectively. These processes are exquisitely regulated and protect the organism from excessive blood loss or excessive fibrin deposition. Regulation of these cascades is accomplished by a variety of mechanisms involving cellular responses, flow, and protein-protein interactions. With respect to regulation mediated by pro...
متن کاملThrombin-activatable fibrinolysis inhibitor antigen levels and cardiovascular risk factors.
Thrombin-activatable fibrinolysis inhibitor (TAFI) is a recently described fibrinolysis inhibitor that circulates in plasma as a procarboxypeptidase and is converted into an active form during coagulation. The physiological relevance of TAFI is not known, but it might be involved in pathways regulating fibrin deposition. Our aim was to determine the interindividual variability of plasma TAFI an...
