Cytokines such as tumour necrosis factor-alpha and interferon gamma are associated with active pulmonary inflammation in sarcoidosis and they upregulate inducible nitric oxide synthase (iNOS). The objectives of this study were to examine iNOS upregulation in sarcoidosis by showing raised exhaled nitric oxide and increased iNOS activity in lung biopsy specimens of these patients utilizing immuno...
LSTRA is a mouse lymphoma cell line overexpressing the src-related oncogene product and T cell marker p56lck. We have discovered that LSTRA cells, like HL60 and U937 promyelocytic leukemia cells, can be induced to differentiate toward macrophages by the phorbol ester 12-O-tetradecanoyl phorbol-13-acetate (TPA) or granulocytes by the cyclic nucleotide analogue dibutyryl cAMP (dbcAMP). One proper...
nitric oxide is an important vasorelaxant factor that it inhibits platelet adhesion and proliferation of smooth muscle cells. no is synthesized from l-arginine by means of endothelial nitric oxide synthase (enos) which is an isoform of nitric oxide synthase.in the present study, we examined possible association between the 27 base pair (bp) repeat polymorphism in intron 4 of the enos3 gene ...
OBJECTIVE To analyze immunocompetent cells as well as 2 factors involved in inflammation and also thought to be involved in bone remodeling-interleukin 6 (IL-6) and inducible nitric oxide synthase in the human middle ear, including the tympanic membrane. DESIGN Biopsy specimens were obtained from the human middle ear and tympanic membrane during surgery. Using an immunohistochemical technique...
In cystic fibrosis (CF), low concentrations of exhaled nitric oxide (NO) and reduced expression of inducible nitric oxide synthase (iNOS) in airway epithelium have been reported. However, abundant iNOS expression has been found in the subepithelial tissues and elevated concentrations of NO metabolites in breath condensate and sputum. These conflicting results may be explained by increased scave...
