HAE-PLG, HAE-FXII, HAE-C1-INH and HAE-HK represent forms of hereditary angioedema related to gain-offunction mutations in each factor. This is attributable to plasmin-driven bradykinin production, fitting with the clinical observation that bradykinin-driven angioedema is a rare (1–5%) side-effect of thrombolytic therapy . Bradykinin causes the production of histamine and nitric oxide to increase. Plasminogen activation is essential for fibrinolysis-the breakdown of fibrin polymers in blood clots. 10.1182/blood-2017-04-569111 The nonapeptide bradykinin (BK) appears to act as a mediator of a wide variety of physiological and pathophysiological responses including pain and inflammation (Farmer and Burch, 1992; Hall, 1992). Bradykinin, an inflammatory mediator, sensitizes nociceptor peripheral terminals reducing pain threshold. One of these conditions is hereditary angioedema (HAE), a rare disease with characteristic attacks of aggressive tissue swelling due to unregulated production and activity of the inflammatory mediator bradykinin.

Prekallikrein is the precursor to the enzyme kallikrein, which then produces bradykinin by cleaving yet another molecule called kininogen.

Two bradykinin receptors, bradykinin B1 receptor (B1R) and bradykinin B2 receptor (B2R), were significantly expressed in all the tested colorectal cancer cells. Again bradykinin B 2 receptor blockade further increased rather than decreased the effect of Ang II on cyclic GMP production. Pathway to Bradykinin Production. Ann Allergy Asthma Immunol. 2016 Nov;138(5):1414-1423.e9. This is amongst others supported by findings in subtypes of HAE that are caused by gain-of-function mutations in the genes that respectively encode factor XII or plasminogen, as well as clinical experience with the antifibrinolytic agents in HAE. Binding data revealed a calcium-independent binding of bradykinin to the cell membrane with a receptor density of 25,000 receptors per cell and a Kd of 1.6 nM.

Two BK receptors, B1R and B2R, have been identified. BK directly excites nociceptive dorsal root ganglia (DRG) neurons and causes pain in animals and human (Steranka et al., 1988; Mizumura et al., 1990; Manning et al., 1991; Levine et al., 1993; Couture et al., 2001). However, brain edema after thrombolytic therapy is much more common and generally considered an unavoidable treatment-associated evil. Inflammation is the first step in wound healing. Low levels of bradykinin are continuously formed and present in the blood-stream. In examining the DNA sequence of the patient’s prekallikrein gene , physicians discovered a mutation that caused a premature stop in the production of kallikrein protein. J Thromb Haemost. Regulation of cell signalling by uPAR. Prevention and treatment information (HHS). 1997; 97:264–269. 2019 Aug 27;10:2046. doi: 10.3389/fimmu.2019.02046. Plasmin was already implicated in this disease decades ago, but a series of recent discoveries have made it clear that plasmin actively contributes to this pathology. Plasmin is a natural trigger for bradykinin production in patients with hereditary angioedema with factor XII mutations. This suggests the presence of a second pathway generating bradykinin in vivo. Am J Physiol. Vasodilators work by relaxing the smooth muscle cells that are within our vessel walls. Immunol. Murine models of FXII deficiency indicate that the basal production of bradykinin in plasma is approximately 50 % dependent on FXII [56]. Bradykinin has important physiological actions related to the regulation of blood vessel tone and renal function, and protection from ischemia reperfusion injury. 1996;271(Regul Integr Comp Physiol 40):R1090–R1095. 10.1097/MBC.0000000000000735 Effect of captopril and the bradykinin-PKC pathway on ROS production in type 1 diabetic rats. Researchers found an increased expression of enzymes that can trigger the production of bradykinin and a decreased expression of enzymes that would break down bradykinin — the perfect storm. The study team believe that this research explains many aspects of COVID-19 that were previously not understood, including why there is an abnormal accumulation of fluid in the patients’ lungs. Renin-angiotensin system modulates renal bradykinin production. It also causes contraction of non-vascular smooth muscle in the bronchus and gut, increases vascular permeability and is also involved in the mechanism of pain. eCollection 2019. %PDF-1.4 Domain architectures of factor XII and tissue-type plasminogen activator. Bradykinin is a potent endothelium-dependent vasodilator and mild diuretic, which may cause a lowering of the blood pressure. Increased bradykinin levels trigger symptoms of an HAE attack 1,2. 1.

Repression of B2R, but not B1R, attenuated the BK-mediated invasion and migration, and inhibited ERK1/2 activation and IL-6 production. However, bradykinin also contributes to pathological states such as angioedema and inflammation. 2021 Jan 9;32:100712. doi: 10.1016/j.ijcha.2020.100712. COVID-19 is an emerging, rapidly evolving situation. In healthy men, bradykinin (100-3200 ng/kg min) dose-related increased plasma concentrations of 6-oxo-PGF1a , the stable hydrolysis product of prostacyclin (PGI2). Bradykinins (BKs) belong to a family of short, structurally similar peptides that are important metabolites of the kallikrein-kinin system. 2016 Nov;138(5):1414-1423.e9. However, brain edema after thrombolytic therapy is much more common and generally considered an unavoidable treatment-associated evil. Keywords: It’s a peptide, which means it’s made up of amino acids (nine, in this case) that are linked together. (2010) 11:23–36. <> Joseph K, Tholanikunnel BG, Wolf B, Bork K, Kaplan AP. Histamine allows fluid to leak out of the blood vessels, and nitric oxide relaxes and widens the blood vessels [22, 2, 24, 25, 6, 26]. Int J Cardiol Heart Vasc. Two bradykinin receptors, bradykinin B1 receptor (B1R) and bradykinin B2 receptor (B2R), were significantly expressed in all the tested colorectal cancer cells. (1998) 1:3300–7. Hypoxia stimulates urokinase receptor expression through a heme protein-dependent pathway. Vascular endothelial growth factor increases urokinase receptor expression in vascular endothelial cells. Because bradykinin (BK) and interleukin (IL)-6 may play important roles in the regulation of airway inflammation, we tested whether BK induces IL-6 expression from human ASM cells. References: [1].
