Hereditary angioedema with normal levels of C1 inhibitor (HAE-N) is associated with mutations in Factor XII in 30% of subjects; However, the role of this mutation in the pathogenesis of angioedema is unclear. We are looking for evidence of abnormalities in the pathway of bradykinin bradykinin formation and degradation in the plasma of patients with HAE-N both with and without the mutation.
Bradykinin has been added to the plasma, and the degradation rate was measured using ELISA. autoactivation Plasma assessed using a chromogenic assay kallikrein formation. Plasminogen activator inhibitor (Pais) 1 and 2 were measured by ELISA method.
PAI-1 levels varied from 0.1 to 4.5 ng / mL (median, 2.4 ng / mL) in 23 control subjects, 0.0 to 2 ng / mL (mean, 0.54 ng / ml) in patients with HAE-N with factor XII mutations (12 samples), and 0.0 to 3.7 ng / mL (mean, 1.03 ng / mL) in patients with HAE-N without factor XII mutation (11 samples). PAI-2 levels vary 25-87 ng / mL (median, 53.8 ng / mL) in control subjects and 0-25 ng / mL (median, 4.3 ng / mL) in patients with HAE- N with or without the mutation Factor XII. Autoactivation at 1: 2 dilution is abnormally high in 8 of 17 patients with HAE-N (4 in each sub-category) and can be corrected with additional C1 inhibitor in 4 of them. bradykinin degradation is real abnormal in 1 out of 23 patients with HAE-N and normal in the remaining 22 patients.
bradykinin degradation is normal in all but one of 23 patients with HAE-N studied. Conversely, there are disorders characterized in PAI-2 levels in patients with HAE-N were not seen in patients with C1 inhibitor deficiency. PAI-1 levels vary, but the difference was not statistically significant visible. A link between excessive fibrinolysis and bradykinin generation suggested that estrogen dependent.
Deficiency of plasminogenactivatorinhibitor2 in plasma of patients with hereditary angioedema with normal C1 inhibitor levels.
Copper (II) ions Increases Plasminogen Activator Inhibitor Type 1 Structural Dynamics in Key Regions Memerintah Stability.
Plasminogen activator inhibitor type 1 (PAI-1) regulates the fibrinolysis pathway by inhibiting the protease activity of plasminogen activators. PAI-1 works in concert with vitronectin (VN), an extracellular protein that aids in localization of active PAI-1 to the network. Peterson laboratory showed that Cu (II) and other transition metals modulate the stability of PAI-1, the effect of which depends on the presence or absence of somatomedin B (SMB) domain of VN show.
The studies presented here dissect the molecular changes underlying dynamics destabilizing effect of Cu (II) on PAI-1. We use exchange backbone amide hydrogen / deuterium monitored by mass spectrometry to assess the dynamics of PAI-1 in the presence and absence of Cu (II) ion with and without the SMB domain of VN. We show that Cu (II) results in improved dynamics in areas essential to the function and the overall stability of PAI-1, whereas the SMB domain elicits almost the opposite effect.
A mutant form of PAI-1 less two histidine residues N-terminal in position 2 and 3 exhibit a similar rise in the dynamics of the Cu (II) binding compared to an active wild type PAI-1, suggesting that the structural effect observed is not the result of coordination of Cu ( II) to the histidine residues.

Finally, the addition of Cu (II) produces an acceleration of the kinetics of local unfolding of PAI-1 are thought to be on the path to conversion latency. The influence of the ligand on the dynamics of PAI-1 adds another interesting dimension to the mechanism of regulation of PAI-1 stability and function.
