Elastase inhibitor. Characterization of the human elastase inhibitor molecule associated with monocytes, macrophages, and neutrophils
A fast-acting inhibitor of serine elastase has been detected at high levels in human neutrophils, fresh monocytes, matured monocytes, and macrophages. The elastase inhibitor was isolated from large scale cultures of the monocyte-like cell line U937 by DNase chromatography, disulfide exchange, Phenyl-Sepharose, Red A-agarose, and DEAE HPLC chromatography with an average yield of 480 micrograms f...
متن کاملElastase and elastase inhibitor from Aspergillus fumigatus, Aspergillus flavus and Aspergillus niger.
Elastolytic and elastase inhibitory activities were investigated for 13 strains of Aspergillus fumigatus, three strains of Aspergillus flavus and three strains of Aspergillus niger. Nine of the 13 strains of A. fumigatus and all strains of A. flavus demonstrated elastase activity (more than 1 unit ml(-1)). Six of the 13 strains of A. fumigatus and all strains of A. flavus expressed elastase inh...
متن کاملArterial elastase activity after balloon angioplasty and effects of elafin, an elastase inhibitor.
Increased proteolytic activity may be a factor in intimal hyperplasia after balloon angioplasty (BA). The objectives of this study were to assess elastase activity after BA in a rabbit arterial double-injury model and the effects of elastase inhibition. Elastase activity increased immediately after BA, reached an 8-fold peak at 1 week, and declined to baseline levels by 4 weeks. Elastin zymogra...
متن کاملneutrophil elastase inhibitor following liver resection: a matched cohort study
background sivelestat is a neutrophil elastase inhibitor (nei) with positive impact on the respiratory complications in thoracic surgery. based on the findings of a recent study, nei may have a good response for avoiding ischemia reperfusion injury in liver resection. conclusions intravenous nei administration had positive impact on the postoperative inflammatory response and oxygenation while ...
متن کاملPseudomonas aeruginosa elastase does not inactivate alpha 1-proteinase inhibitor in the presence of leukocyte elastase.
Pseudomonas aeruginosa elastase rapidly inactivates alpha 1-proteinase inhibitor by splitting its Pro-357-Met-358 peptide bond. The present study was aimed at testing whether this reaction takes place in the presence of leukocyte elastase. To this end was added alpha 1-proteinase inhibitor to a mixture of the two elastases, and we performed the following assays: (i) measurement of the residual ...
