Eosinophil inflammation of nasal polyp tissue: relationships with matrix metalloproteinases, tissue inhibitor of metalloproteinase-1, and transforming growth factor-beta1.
Eosinophil and mast cell infiltrations are consistent findings in nasal polyp tissue. Previous studies have shown that matrix metalloproteinases (MMPs) may be involved in eosinophil infiltration in airway mucosa of asthmatic patients, and that transforming growth factor-beta1 (TGF-beta1) induces extracellular matrix deposition in nasal polyp tissue. The aim of this study was to evaluate the rol...
متن کاملMatrix metalloproteinases, tissue inhibitor of metalloproteinase and transforming growth factor A1 in the remodeling of chronic rhinosinusitis in North China
Results MMP-8,9 were the highest among all above MMPs. MMP-8 of NP tissue was much higher than that of CRS and control tissue (P<0.001). MMP-9 of NP tissue was also significantly higher than that of CRSsNP and control tissue (P<0.05). MMP-7 of NP tissue and CRSsNP were much higher than that of control tissue (P<0.001). MMP2 of CRSsNP tissue was much higher than that of NP and control tissue (P<...
متن کاملInterleukin-13 augments transforming growth factor-beta1-induced tissue inhibitor of metalloproteinase-1 expression in primary human airway fibroblasts.
Tissue inhibitor of metalloproteinase (TIMP)-1 is a potent inhibitor of activated matrix metalloproteinases (MMPs) such as gelatinases and collagenases. TIMP-1 is induced by transforming growth factor-beta1 (TGF-beta1), but details regarding signaling pathways remain unclear. T-helper-2 cytokines also have profibrotic properties and can interact with TGF-beta. In the present study, we examined ...
متن کاملMatrix metalloproteinase-2, tissue inhibitor of matrix metalloproteinase-2, and transforming growth factor beta 1 in the aqueous humor and serum of patients with pseudoexfoliation syndrome
PURPOSE The aim of the study reported in this article was to determine the presence and quantitative differences of matrix metalloproteinase-2 (MMP-2), its tissue inhibitor (TIMP-2) and transforming growth factor beta 1 (TGF-β1) in the aqueous humor and serum samples of patients with pseudoexfoliation (PEX) syndrome. METHODS Aqueous humor and serum samples were collected from 32 patients with...
متن کاملEffect of doxycycline and meloxicam on cytokines, brain-derived neurotrophic factor, matrix metalloproteinase-3, tissue inhibitor of metalloproteinase-3 and cyclooxygenase-2 in brain
Objective(s): Prevention of inflammation in early stages will be useful in maintaining vitality of the organism. The objective of this study was to evaluate the effects of doxycycline (DOX) or meloxicam (MLX) monotherapy and combination therapy on the levels of inflammatory mediators in the brain tissues of rats with Escherichia coli lipopolysaccharide (LPS)-induced br...
