OBJECTIVE
Bronchoalveolar lavage (BAL) is useful in diagnosis and management of interstitial lung diseases. Glutathione (GSH) represents an important defence molecule against reactive oxygen species produced during inflammation, which underlies both idiopathic pulmonary fibrosis (IPF) and
In order to investigate the change of glutathione concentration in BAL from the patients with diffuse interstitial lung disease. We measured the levels of glutathione in BAL from the patients with interstitial lung disease, including idiopathic interstitial pneumonitis (IIP), hypersensitivity
OBJECTIVE
The glutathione system has a key role in the defence against oxidative stress. To function properly, this system needs NADPH to maintain glutathione (GSH) in its reduced form. We hypothesized that the clinical problems associated with sarcoidosis might be related to a decreased
Sarcoidosis is a chronic inflammatory disease, characterized by granulomatous inflammation, prominently involving the respiratory system. The etiology of this disease has not yet been elucidated and the contribution of genetic is not yet completely understood. We searched for novel candidate genes,
BACKGROUND
Enhanced production of reactive oxygen species (ROS), capable of reducing endogenous defense levels and enhancing inflammation, is suggested to play a role in sarcoidosis. Antioxidant supplementation might offer protection against such ROS-mediated damage. A promising candidate for
DNA damage caused by free radicals is one of the mechanisms which are responsible for the occurrence of lung tumors, especially in case of cigarette smokers.Their tumors are radiologically often disseminated changes.
OBJECTIVE
To define the correlation between GPX activity in erythrocyte hemolysate
Glutaredoxins (Grx) are thiol-disulfide oxidoreductases with antioxidant capacity and catalytic functions closely associated with glutathione, an antioxidant abundantly present in human lung. The present study investigated the expression of both human glutaredoxins in cultured human lung cells and
Tumour necrosis factor (TNF) blockade has become an important immunomodulatory therapy, particularly in patients refractory to conventional immunosuppression, but responses can be unpredictable. Understanding the complex biology of TNF processing may be key to predicting such responses and reduce
The proteomic approach applied to the analysis of BAL gives a panorama of the complex network of proteins of different origin and function and their modifications at alveolar level. Cigarette smoking may influence BAL protein composition and it represents the most relevant risk factor The pathogenesis of interstitial lung diseases (ILDs) is known to be associated with reactive oxygen and nitrogen metabolites and increased oxidant stress. One of the major antioxidants in human lung is glutathione (GSH) and enzymes linked to its synthesis. The rate-limiting enzyme of GSH synthesis
Inhalation therapy has matured to include drugs that: (1) deliver nucleic acids that either lead to the restoration of a gene construct or protein coding sequence in a population of cells or suppress or disrupt production of an abnormal gene product (gene therapy); (2) deliver peptides that target
All six mammalian peroxiredoxins are expressed in the lung. Peroxiredoxin (Prx) VI is the isoform expressed at the highest level and its lung expression exceeds that for other organs. The predominant location of Prx VI is the cytosol and acidic organelles of Clara cells of the conducting airways and
OBJECTIVE
To evaluate the relationship between enzymatic activities in bronchoalveolar lavage fluid(BALF) and interstitial lung diseases(ILDs).
METHODS
Cellular components and levels of superoxide dismutase (SOD), glutathione peroxidase(GSH-PX), angiotensin converting enzyme(ACE) and lactate
Chronic beryllium disease (CBD) is characterized by accumulation of macrophages and beryllium-specific CD4+ T cells that proliferate and produce Th1 cytokines. 5-Amino salicylic acid (5-ASA) is currently used to treat inflammatory bowel disease and has both antioxidant and anti-inflammatory actions.
This study investigated the hypothesis that inflammatory, regulatory and antioxidant systems control the redox balance in interstitial lung diseases. Spontaneous mRNA expression of inflammatory cytokines and redox-active enzymes was examined in bronchoalveolar lavage (BAL) cells from patients with
