The kinin–kallikrein system or simply kinin system is a poorly understood hormonal system with limited available research. It consists of blood proteins that play a role in inflammation, blood pressure control, coagulation and pain. Its important mediators bradykinin and kallidin are vasodilators and act on … See more The system was discovered in 1909 when researchers discovered that injection with urine (high in kinins) led to hypotension (low blood pressure). The researchers Emil Karl Frey, Heinrich Kraut and Eugen Werle discovered high … See more The system consists of a number of large proteins, some small polypeptides and a group of enzymes that activate and deactivate the compounds. Proteins See more Inhibition of ACE with ACE inhibitors leads to decreased conversion of angiotensin I to angiotensin II (a vasoconstrictor) but also to an increase in bradykinin due to decreased degradation. This explains why some patients taking ACE inhibitors develop a dry cough, … See more • Kallikrein-Kinin+System at the U.S. National Library of Medicine Medical Subject Headings (MeSH) See more • Kallikreins (tissue and plasma kallikrein) are serine proteases that liberate kinins (BK and KD) from the kininogens, which are plasma proteins that are converted into vasoactive peptides. See more Defects of the kinin-kallikrein system in diseases are not generally recognized. The system is the subject of much research due to its relationship to the inflammation and See more C1-inhibitor is a serine protease inhibitor (serpin) protein. C1-INH is the most important physiological inhibitor of plasma kallikrein, fXIa and fXIIa. C1-INH also inhibits proteinases … See more WebUrinary kallikrein, a glycoprotein extracted from urine, can activate kallikrein–kinin system (KKS) and thus transfer kininogen hydrolysis into kallidin and kinin. 1 Kinin in turn could activate B1 and B2 receptors induced by ischemic brain tissue and trigger a series of biological effects, releasing nitric oxide and relaxing vascular smooth …
