Coagulation factor FXIII, composed of two catalytic A and two carrier B subunits, is activated into FXIIIa by thrombin. FXIIIa catalyses cross-linking of fibrin polymers and plasmin inhibitor (PI The coagulation cascade refers to the series of steps that occur during the formation of a blood clot after injury by activating a cascade of proteins called clotting factors. There are three pathways: intrinsic, extrinsic, and common. The intrinsic pathway is activated by factors in the blood, while extrinsic is activated by tissue factor Background: The expression of coagulant factor XIII subunit A (FXIII-A) is significantly increased in some types of cancer cells and tumor-associated macrophages (TAMs). However, few studies on plasma FXIII-A in cancer patients have been conducted and have shown contradictory results, so the relationship of plasma FXIII-A with the D-dimer is a terminal degradation product from the breakdown of fibrin. Unlike other fibrin degradation products, D-dimer is formed only after fibrin has been cross-linked by factor XIII and lysed by plasmin [ 78 ]. Quantitative D-dimer is most often used in the evaluation of venous thrombosis and DIC

The activity of blood coagulation factor XIII (FXIIIa) plays an important role in rodents as a healing factor after MI, whereas its role in healing and remodelling processes in humans remains unclear. We prospectively evaluated the relevance of FXIIIa after acute MI as a potential early prognostic marker for adequate healing Factor XIII, an enzyme that cross-links fibrin, belongs to the blood coagulation system. [ 1, 2] Screening for factor XIII, also known as fibrin-stabilizing factor, is performed when its absence is suspected. [ 3] Qualitatively, factor XIII levels are referred to as decreased or normal. [ 4] Quantitation of the enzyme's levels is carried out in We aimed to identify the predictive value of coagulation factor XIII (FXIII) on post-thrombolytic ICH risk in AIS patients. Methods: The study cohort included 69 diagnosed AIS patients undergoing IVT treatment within 24 hours of symptom onset. Blood samples taken on admission were analyzed for FXIII antigen levels with an automated latex Factor XIII, an enzyme that cross-links fibrin, belongs to the blood coagulation system. [ 1, 2] Screening for factor XIII, also known as fibrin Any imbalance in the system may affect the clot structure, stability and its resistance to fibrinolysis. Thus, all the elements involved in the clot formation are important determinants of atherothrombotic risk, and so are fibrinogen and coagulation factor XIII Coagulation factor XIII (FXIII) is a transglutaminase with a well defined role in the final stages of blood coagulation. Active FXIII (FXIIIa) catalyzes the formation of ϵ- (γ-glutamyl)lysine isopeptide bonds between specific Gln and Lys residues. The primary physiological outcome of this catalytic activity is stabilization of the fibrin clot
Coagulation factor XIII: a multifunctional transglutaminase with ...
Abstract. The blood coagulation factor XIII (FXIII) plays an essential role in the stabilization of fibrin clots. This factor, belonging to the class of transglutaminases, catalyzes the final step of secondary hemostasis, i.e. the crosslinking of fibrin polymers. These crosslinks protect the clots against premature fibrinolysis Plasma factor XIII is a tetrameric molecule composed of 2 A-subunits of kd and 2 B-subunits of kd that are held together noncovalently in a One particular protein of interest, the coagulation factor XIII-A (F13A1) was identified as one of the key down-regulated proteins. In the present study, we develop and describe the outstanding potential of LC–MS/MS and PRM assays for quantifying and validating the endogenous F13A1 in cohorts of human serum samples at different stage Introduction. The coagulation cascade is a series of reactions, catalysed by protein enzymes known as coagulation ‘factors’. When activated, Summary. Inherited factor XIII (FXIII) deficiency is a rare bleeding disorder that can present with umbilical bleeding during the neonatal period, delayed soft tissue bruising, mucosal bleeding and life-threatening intracranial haemorrhage. FXIII deficiency has also been associated with poor wound healing and recurrent miscarriages
