malfunction
physiological function
malfunction
-
activated partial thromboplastin time is abnormal in all cases with severe or moderate FXI deficiency. FXI deficiency is not an absolute contraindication to neuraxial anesthesia
malfunction
-
FXI deficiency is a rare inherited coagulation disorder characterized by infrequent spontaneous bleeding, but increased risk of hemorrhagic complications especially after trauma or surgery
malfunction
-
a deficiency in FXI (hemophilia C) results in a more benign bleeding phenotype compared with a deficiency in either FVIII (hemophilia A) or FIX (hemophilia B). Most hemophilia C cases involve Ashkenazi Jews and result from either of 2 mutations in the FXI gene (E117X and F283L). Greater than 180 mutations are present but in lesser frequency. FXI deficiency also arises from acquired inhibitors that neutralize its activity, these patients may not respond well to FXI replacement therapy. Bleeding in those with hemophilia C is rarely spontaneous, it tends to occur in response to surgery or trauma, and especially in tissue prone to fibrinolysis (the urinary track or oral cavity). Prolonged activated partial thromboplastin time due to FXI deficiency
malfunction
-
FXI-null mice are healthy, and their reproduction follows the expected mendelian ratios without impaired fecundity. FXI-null mice are protected against oxidative iron chloride-induced carotid artery thrombosis and infusion of human FXI reverses this protection. Thrombus formation in FXI-null mice is also reduced in response to laser injury of arterioles in the cremaster muscle. FXI deletion is also effective in preserving carotid artery blood flow in response to compression injury
malfunction
-
congenital FXI deficiency is associated with a variable, mild to moderate bleeding disorder. Severe deficiency is prevalent in people of Jewish ancestry. The severe mutation Glu117Stop encodes a truncated protein, and homozygotes lack plasma FXI antigen. The more subtle missense mutation Phe283Leu causes a defect in FXI dimer formation. Most cases of FXI deficiency are associated with low plasma levels of FXI protein. Deficiency or inhibition of FXI interferes with platelet accumulation in growing thrombi. A4 domain mutations associated with FXI deficiency interfere with dimerization. FXI-deficient plasma exhibits a prolonged activated partial thromboplastin clotting time
malfunction
-
mice lacking FIX, FXI, or FXII on a background of low tissue factor expression have a severe bleeding disorder but are viable. Superimposing FIX or FXI deficiency on the low tissue factor background results in death in utero from bleeding
malfunction
-
FXI deficient humans suffer from mild hemorrhage (hemophilia C), which is characterized by trauma or soft tissue-related hemorrhage, primarily involving tissues with high fibrinolytic activity. Bleeding severity in FXI deficiency is not associated with FXI plasma levels. Addition of murine FXI to human FXI deficient plasma rescues the prolonged activated partial thromboplastin time, but with a slightly reduced activity compared with the human protein
malfunction
-
addition of murine FXI to human FXI deficient plasma rescues the prolonged activated partial thromboplastin time, but with a slightly reduced activity compared with the human protein. FXI-/- mice are healthy, fertile, and phenotypically indistinguishable from wild-type animals. Mating between heterozygous FXI+/- mice follows the expected Mendelian ratio arguing against an association of FXI deficiency and increased risk of abortion. Plasma from FXI null mice show a severely prolonged activated partial thromboplastin time compared with wild-type animals. Bleeding times in adult FXI-/- mice are indistinguishable from wild-type animals, suggesting that FXI does not significantly contribute to fibrin formation. Formation of thrombi is severely defective in FXI-/- mice. Both fibrin deposition and platelet accumulation are reduced in FXI null mice compared with wild-type. FXI deficiency increases survival and reduces leukocyte infiltration and coagulopathy
malfunction
-
patients who have a very severe FXI deficiency are prone to development of inhibitor antibodies. During major surgeries, a single low dose of recombinant activated factor VII and tranexamic acid secure normal haemostasis in patients with severe FXI deficiency who can not receive blood products
malfunction
-
factor XI deficiency can lead to delayed clot formation and decreased thrombin generation
malfunction
-
enzyme deficiency results in bleeding diathesis referred to as hemophilia C
physiological function
-
FXI is a biomarker with increased levels reported as a risk factor for venous thromboembolism and myocardial ischemia or stroke
physiological function
-
involvment of FXI in thrombosis, role for activated factor FXI in tissue infammation
physiological function
-
FXI is the zymogen of a blood coagulation protease, factor XIa (activated factor IX), that contributes to hemostasis through activation of factor IX. Almost all FXI circulate in a complex with kininogen
physiological function
-
FXI is the zymogen of a plasma protease that contributes to fibrin formation and stability by activating factor IX. Circulates in plasma in complex with high molecular weight kininogen
physiological function
-
the opossum genome has two distinct genes for both FXI and plasma kallikrein, indicating that the gene duplication event leading to separate factors occurred early in mammalian evolution
physiological function
-
78% homology to human FXI at the protein level. FXI is critical for fibrin formation in vivo. FXI may have additional functions in regulation of inflammation or tissue repair distinct from its role in coagulation
physiological function
-
presence of a single precursor of FXI and plasma kallikrein, appearance of FXI among early tetrapods
physiological function
-
activated factor XI inhibits chemotaxis of polymorphonuclear leukocytes. Coagulation factor XI participates in the intrinsic coagulation pathway upon its activation, contributing to hemostasis and thrombosis. Factor XIa attenuates N-formylmethionyl-leucyl-phenylalanine-induced Ca2+mobilization
physiological function
-
factor XIa plays its major role in promoting late thrombin formation (i.e. the thrombin required for thrombin activatable fibrinolysis inhibitor-mediated inhibition of fibrinolysis)
physiological function
-
activated factor XI increases the procoagulant activity of the extrinsic pathway by inactivating tissue factor pathway inhibitor
physiological function
-
factor XI is important in the tissue factor-independent propagation phase of clot formation, not in the initiation process

activated factor IX
-
autoactivation, cleavage of FXI at the Arg369-Ile370 bond. activated factor IX is part of a feedback loop that sustains thrombin generation through FIX activation to consolidate coagulation
-
activated factor XII
-
FXI activation proceeds through an intermediate with only one activated submit
-
activated factor XII
-
activated factor XII-mediated activation of FXI appears to play a central role in formation of pathologic thrombi in murine thrombosis models
-
desmopressin
-
increase of both FXI activity (up to 31%) and antigen levels 60 min after infusion. Also contradictory results with a lack of rise of FXI levels after infusion
Factor XII
-
FXI is activated by factor XII during ischemia reperfusion injury and within the growing thrombus according to the classical intrinsic pathway cascade
-
thrombin
-
FXI activation proceeds through an intermediate with only one activated submit
-
thrombin
-
thrombin generated early in coagulation by the tissue factor pathway activates FXI creating a positive feedback loop that sustains coagulation following inactivation of the factor VIIa/tissue factor complex by tissue factor pathway inhibitor
-
thrombin
-
activated factor V is a cofactor for the activation of factor XI by thrombin. Depletion of factor V, or the addition of activated protein C, decreases the activation of the intrinsic pathway by thrombin in plasma. Factor XI binds to factor V with multiple binding sites. Addition of FVIIIa, kininogen, or protein S does not influence the formation of activated factor XI
-
thrombin
-
activates FXI. FXI activation by thrombin is enhanced by charged substances, such as dextran sulfate or heparin. Thrombin binds to the A1 domain of FXI, with residues Glu66, Lys83, and Gln84 forming part of the binding site. The dimer is required for optimal FXI activation by thrombin
-
additional information
-
activation of factor XI by thrombin and autoactivation to factor XIa
-
additional information
-
platelets may play a role in FXI activation. FXI binding to platelets is not enhanced by kininogen
-
additional information
-
FXI monomers are activated poorly, dimeric form is needed for activation. As FXI lacks a Gla domain, the dimeric structure may represent an alternative solution to the problem of tethering a prothrombotic molecule to a cellular surface in flowing blood in the vicinity of a wound
-
additional information
-
in blood challenged with low concentrations of tissue factor, factor XI can be activated independently of factor XII
-
additional information
-
antibody 14E11 exerts an inhibitory effect on fXI activation, but not fXIa activity

-
site-directed mutagenesis, the mutant shows increased platelet binding compared to the wild-type enzyme
additional information
-
FXIa/PKA4 is made by replacing the FXI A4 domain with the A4 domain from prekallikrein. A dimeric version of FXI/PKA4 (FXI/PKA4-Gly326) is prepared as a control. Activated FXIa/PKA4 and FXIa/PKA4-Gly326 activate factor IX with kinetic parameters similar to that of FXIa. FXI/PKA4 and FXIa/PKA4-Gly326 have coagulant activity similar to FXI. FXIa/PKA4, FXIa/PKA4-Gly326 and FXIa have similar affinities for activated platelets. The dimeric proteins FXI and FXI/PKA4-Gly326 promote coagulation similarly, however, monomeric FXIa/PKA4 has greatly reduced activity. The activated monomeric FXIa/PKA4 activates factor IX poorly in the presence of activated platelets

activated factor XI inhibition as a viable method to increase the ratio of benefit to risk in an antithrombotic drug
medicine
-
the enzyme may be a suitable target for the development of an antithrombotic therapy
medicine
-
diagnosis of FXI deficiency may be considered in patients with delayed postoperative bleeding and prolonged activated partial thromboplastin time, especially in a demographically high-risk population, such as Ashkenazi Jews. Women with severe FXI deficiency and prolonged activated partial thromboplastin time can be managed with fresh frozen plasma transfusion before neuraxial anesthesia
medicine
-
treatment options for FXI-deficient patients include virus-inactivated fresh frozen plasma, plasma-derived FXI concentrates, and activated recombinant FVII. Potential role of desmopressin for either treatment of bleeding episodes or the prevention of postoperative bleeding in patients with milder FXI defects. A single desmopressin infusion is sufficient to provide an efficient perioperative hemostasis
medicine
-
therapeutically targeting FXI may offer a strategy for preventing or treating arterial thrombosis that is not associated with the high rate of hemorrhage that accompanies many currently used anticoagulants. Pharmacological FXI inhibitors may be beneficial in septic disease
