Coagulation cascade: It is a series of enzymatic reactions that lead to the formation of a stable blood clot. The endothelial cells release substances like tissue factor, which triggers the extrinsic pathway of the coagulation cascade. This is called as "secondary hemostasis". [20]
Tissue factor, also called platelet tissue factor or Coagulation factor III, [5] is a protein present in subendothelial tissue and leukocytes which plays a major role in coagulation and, in humans, is encoded by F3 gene. Its role in the blood clotting is the initiation of thrombin formation from the zymogen prothrombin.
The two arms of the contact system. PKa's cleavage of HK liberates BK and promotes inflammation. FXIIa's cleavage of FXI initiates coagulation. In the contact activation system or CAS, three proteins in the blood, factor XII (FXII), prekallikrein (PK) and high molecular weight kininogen (HK), bind to a surface and cause blood coagulation and ...
In coagulation, the coagulation factor X can be activated into factor Xa in two ways: either extrinsically or intrinsically. The activating complexes are together called tenase . Tenase is a blend word of "ten" and the suffix "-ase", which means, that the complex activates its substrate (inactive factor X) by cleaving it.
The extrinsic pathway of apoptosis refers to cell death induced by external factors that activate the death-inducing signaling complex. The extrinsic pathway of blood coagulation is also known as the tissue factor pathway and refers to a cascade of enzymatic reactions resulting in blood clotting and is done with the addition of injured tissue ...
The mechanisms behind allergic asthma—i.e., asthma resulting from an immune response to inhaled allergens—are the best understood of the causal factors. In both people with asthma and people who are free of the disease, inhaled allergens that find their way to the inner airways are ingested by a type of cell known as antigen-presenting ...
Early-onset atopic asthma is the most common phenotype of asthma in childhood, called intrinsic asthma in the earlier intrinsic/extrinsic classification. Patients with early-onset atopic asthma frequently have a family history of atopy, and are sensitised to common allergens. This phenotype usually responds well to inhaled corticosteroids, and ...
Characteristics of the velocity of passage of the intrinsic coagulation pathway; Poor plasma (the most convenient to work with, but no realization of the thrombocyte clotting mechanism) Contact activation pathway; Prothrombin time test (or prothrombin test, INR, PT) – velocity of passage of the extrinsic blood coagulation pathway Poor plasma
