Formation of C 8 - CI - Inhibitor , Kallikrein - CI - Inhibitor , and Plasmin - a 2 - Plasmin - Inhibitor Complexes During Cardiopulmonary Bypass
Stimulation of platelets and neutrophils occurs during clinical cardiopulmonary bypass. We investigated whether the classical complement. contact. or fibrinolytic pathways are activated as potential sources of neutrophil agonists. Using enzyme-linked immunosorbent “sandwich” assays specific for Cl 8-C1 -and kallikrein-C1 -inhibitor complexes respectively. we found that there was a modest increa...
متن کاملPlasma levels of C1- inhibitor complexes and cleaved C1- inhibitor in patients with hereditary angioneurotic edema.
C1- inhibitor (C1(-)-Inh) catabolism in plasma of patients with hereditary angioneurotic edema (HANE) was assessed by measuring the complexes formed by C1(-)-Inh with its target proteases (C1-s, Factor XIIa, and kallikrein) and a modified (cleaved) inactive form of C1(-)-Inh (iC1(-)-Inh). This study was performed in plasma from 18 healthy subjects and 30 patients with HANE in remission: 20 with...
متن کاملC1 inactivator inhibition by plasmin.
Plasmin incubated with partially purified C[unk] inactivator produced a decrease in inhibitory activity which was related to the time of incubation and to the concentration of plasmin. This effect of plasmin was not influenced by the purity of the inhibitor preparations. Soybean trypsin inhibitor and tosyl arginine methyl ester (TAMe), substances which block the active enzymic center of plasmin...
متن کاملPlasmin inhibitor interactions. The effectiveness of alpha2-plasmin inhibitor in the presence of alpha2-macroglobulin
alpha2-Plasmin inhibitor and alpha2-macroglobulin were allowed to compete for the protease plasmin. The binding of the enzyme to these inhibitors was assessed by two different but comparable methods. The interactions were completed in 10 s of incubation, and transfer of plasmin from one inhibitor to the other did not occur. Almost as much plasmin was bound to alpha2-plasmin inhibitor in mixture...
متن کاملExpression of platelet C1 inhibitor.
Human platelets contain a pool of C1 inhibitor (C1 INH) distinct from that in plasma. Twelve normal platelet samples washed by centrifugation had a mean platelet C1 INH antigen level of 19.3 +/- 2.8 ng (mean +/- SEM) per 10(8) platelets. These values contrast with the mean +/- SEM platelet C1 INH antigen level of 6.1 +/- 0.9 per 10(8) platelets from 12 C1 INH-deficient patients. The level of pl...
