Fibrinogen is a protein in the blood that plays a key role in blood coagulation. It is produced in the liver and converted into fibrin when blood clotting is initiated. Research in this area typically focuses on understanding the structure, function, and regulation of fibrinogen, as well as its role in various medical conditions such as clotting disorders, cardiovascular disease, and inflammation. Studies may also investigate potential therapeutic interventions related to fibrinogen, such as medications that target its activity or production.
