Fibrinogen (coagulation factor I) is a glycoprotein complex, produced in the liver, [1] that circulates in the blood of all vertebrates. [2] During tissue and vascular injury, it is converted enzymatically by thrombin to fibrin and then to a fibrin-based blood clot. Fibrin clots function primarily to occlude blood vessels to stop bleeding ...
Akassoglou has pioneered investigations of blood-brain barrier integrity and development of neurological diseases. She found that compromised blood-brain barrier integrity leads to fibrinogen leakage into the brain inducing neurodegeneration. Akassoglou is internationally recognized for her scientific discoveries.
Hereditary abnormalities of fibrinogen (the gene is carried on chromosome 4) are both quantitative and qualitative in nature and include afibrinogenaemia, hypofibrinogenaemia, dysfibrinogenaemia, and hypodysfibrinogenemia. Reduced, absent, or dysfunctional fibrin is likely to render patients as hemophiliacs.
Fibronectin has numerous functions that ensure the normal functioning of vertebrate organisms. [6] It is involved in cell adhesion , growth , migration , and differentiation . Cellular fibronectin is assembled into the extracellular matrix , an insoluble network that separates and supports the organs and tissues of an organism.
Fibrinogen beta chain, also known as FGB, is a gene found in humans and most other vertebrates with a similar system of blood coagulation. The protein encoded by this gene is the beta component of fibrinogen , a blood-borne glycoprotein composed of three pairs of nonidentical polypeptide chains.
The fibrinopeptides, fibrinopeptide A (FpA) and fibrinopeptide B (FpB), are peptides which are located in the central region of the fibrous glycoprotein fibrinogen (factor I) and are cleaved by the enzyme thrombin (factor IIa) to convert fibrinogen into covalently-linked fibrin (factor IA) monomers.
Hereditary fibrinogen Aα-Chain amyloidosis is a sub-category of congenital dysfibrinogenemia in which the dysfunctional fibrinogen does not cause bleeding or thrombosis but rather gradually accumulates in, and disrupts the function of, the kidney. [6] Congenital dysfibrinogenemia is the commonest of these three disorders.
Fibrinogen-like protein 1 is a member of the fibrinogen family of proteins, which also includes fibrinogen, fibrinogen-like protein 2, and clotting factors V, VIII, and XIII. FGL-1 is homologous to the carboxy terminus of the fibrinogen beta - and gamma - subunits which contains the four conserved cysteines of that are common to all members of ...
