Neutrophil collagenase/matrix metalloproteinase-8 (MMP-8) and gelatinase B/matrix metalloproteinase-9 (MMP-9) are contained in granules, are quickly exocytosed upon granulocyte activation and efficiently cleave intact and denatured collagens, respectively.
Genetic ablation of gelatinase B protects against endotoxin-induced mortality. a, PGP production was significantly increased in CF samples compared with normal control samples on type I collagen: CF sputum (n 10) and normal control sputum (n 10) were each incubated on. The neutrophil contains numerous granules of various composition and structure.
For decades, the neutrophil was believed to contain only two granule types, peroxisomes, or peroxidase-positive granules, and peroxidase-negative granules. Later, existence of the third type distinguished by the presence of gelatinase hydrolyzing collagen and gelatin was proposed.

Gelatinase B plays several important functions within neutrophil action, such as degrading extracellular matrix. of collagenases 1 and 2, and gelatinases A and B, while collagenase 3 was not found.

Eur J Biochem. Dec 15; (3)– Collagenase is secreted from neutrophils as a latent or proenzyme. In an effort to understand the mechanism of collagenase activation in inflammation, human peripheral neutrophils (PMNs) were isolated and incubated with the tumor promotor, phorbol myristate acetate (PMA), which induces the neutrophils to degranulate and secrete proteinases.
Neutrophil media were then treated with various. Gelatinase and possibly other enzymes stored in this secretory organelle may be involved in the early events of neutrophil mobilization, the response to chemotactic signals and diapedesis.

Collagenase 3 is a true collagenase, i.e. a proteolytic enzyme that efficiently cleaves native triple-helical type I collagen into characteristic 3/4 and 1/4 s neutrophil collagenase (collagenase 2, MMP-8) encoded by a specific gene in human, collagenase activities in. MMP-9 [matrix metalloproteinase 9; metallopeptidase 9; MMP-9, also known as 92 kDa type IV collagenase, 92 kDa gelatinase or gelatinase B (GELB)], is expressed in a variety of cells in the lung.
Here, the mechanisms by which neutrophil collagenase (MMP-8), gelatinase A (MMP-2), and the ectodomain of MT1-MMP (ectMMP) degrade fibrillar collagen were examined.
In particular, the hydrolysis of type I collagen at 37 °C was investigated to identify functional differences in the processing of the two α–chain types of fibrillar collagen.
Neutrophil gelatinase associated lipocalin (NGAL) also known as migration stimulating factor inhibitor (MSFI), human neutrophil lipocalin (HNL), alpha-1 microglobulin related protein, siderocalin or uterocalin is a amino acid glycoprotein encoded by a.
No gelatinase activity could be found in PBMC treated with LPS during that time period (0 to 4 h). We confirmed the nature of the gelatinase identified by zymography as being MMP-9, using a Western blot technique on stimulated neutrophil supernatants (Figure 4).

We found sputum from TB patients had increased MMP-8 concentrations, neutrophil myeloperoxidase (MPO) and neutrophil gelatinase associated lipocalin (NGAL) compared to controls.
MMP-8 was strongly associated with markers of neutrophil activation, MPO and NGAL, indicating that sputum MMP-8 is likely to be neutrophil-derived. Comparable to SLPI, MMP-9, also called gelatinase B, is produced and secreted by immune cells, in particular by neutrophils, and attributed antimicrobial and immune-modulatory functions.
In addition, MMP-9 is implicated in many chronic lung pathologies, including bronchiectasis (29) and cystic fibrosis.
Furthermore, because sputum trypsin activates human progelatinase B, it may be responsible in part for the reported presence of activated matrix metalloproteinases in CF sputum.
the identification and purification of an active, trypsin-like protease from purulent cystic fibrosis (CF) sputum was first reported by Viscarello and colleagues (11).
Evidence for the contribution of neutrophils to the pathogenesis of pulmonary emphysema is not convincing. We evaluated neutrophil involvement in subclinical pulmonary emphysema by measuring human neutrophil lipocalin (HNL) and two matrix metalloproteinases, gelatinase B (MMP-9) and neutrophil collagenase (MMP-8), in bronchoalveolar lavage fluid (BALF) from 65 community-based.

Theenzymepurified to ahigh specific activity was found to .Among MMPs secreted from neutrophils may be interstitial collagenase (MMP-8) initiating the cleavage of the triple helix of native collagen types I, II, III, and X, and 92 kDa gelatinase (MMP-9) cleaving native types IV and V collagens, and to a lesser extent, fibronectin, laminin, entactin, and insoluble elastin.
Thus, with regard to collagen.To examine the clinical significance of neutrophil gelatinase in rheumatic diseases, plasma and synovial fluid (SF) gelatinase levels were determined in 62 patients with rheumatoid arthritis (RA), 12 patients with ankylosing spondylitis (AS), 18 patients with osteoarthritis (OA) and 17 healthy controls.
The gelatinase level was measured by enzyme-linked immunoassay (ELISA).
