Haemostasis stops bleeding at the site of vascular injury and maintains the integrity of blood
vessels through clot formation. This regulated physiological process consists of complex …

Platelets—blood cells continuously produced from megakaryocytes mainly in the bone
marrow—are implicated not only in haemostasis and arterial thrombosis, but also in other …

Hemostasis encompasses the tightly regulated processes of blood clotting, platelet
activation, and vascular repair. After wounding, the hemostatic system engages a plethora of …

The contact activation system (CAS) and kallikrein/kinin system (KKS) are older recognized
biochemical pathways that include several proteins that skirt the fringes of the blood …

Evolving information has identified disease mechanisms and dysregulation of host biology
that might be targeted therapeutically in coronavirus disease 2019 (COVID-19). Thrombosis …

The contact system is a plasma protease cascade initiated by factor XII (FXII) that activates
the proinflammatory kallikrein‐kinin system and the procoagulant intrinsic coagulation …

Platelets in a thrombus interact with (anti) coagulation factors and support blood
coagulation. In the concept of cell‐based control of coagulation, three different roles of …

Abstract Coagulation factor XII (FXII, Hageman factor, EC= 3.4. 21.38) is the zymogen of the
serine protease, factor XIIa (FXIIa). FXII is converted to FXIIa through autoactivation induced …

Platelets interact with the coagulation system in a multitude of ways, not only during the
phases of thrombus formation, but also in specific areas within a formed thrombus. This …
