Apoptosis resistant bronchoalveolar lavage (BAL) fluid lymphocytes in sarcoidosis.
BACKGROUND Sarcoidosis is a chronic granulomatous lung disease of unknown origin. The accumulation of activated T cells at sites of inflammation represents an early stage in granuloma formation. Since mechanisms governing the normal resolution of inflammatory processes are poorly understood, this study aimed to investigate the apoptotic phenotype of peripheral blood and lung T lymphocytes from ...
متن کاملBronchoalveolar lavage in sarcoidosis.
There is no single cell type present in bronchoalveolar lavage (BAL) fluid that appears to be predictive for sarcoidosis. However, BAL fluid analysis can be very helpful in the differential diagnosis. A grouping of features, an elevated total cell count, predominantly lymphocytes, together with a nearly normal percentage of eosinophils and polymorphonuclear neutrophils and the absence of plasma...
متن کاملAngiotensin converting enzyme in bronchoalveolar lavage fluid in pulmonary sarcoidosis.
Alveolar angiotensin converting enzyme (ACE) and serum ACE were measured simultaneously in 16 patients with histologically confirmed sarcoidosis and in 16 control subjects. Although alveolar ACE was abnormally elevated in all 15 cases of active sarcoidosis, serum ACE was not. No correlations were found between radiographic staging of pulmonary sarcoidosis and the levels of these enzymes. There ...

Background Sarcoidosis is a systemic disease of unknown aetiology characterised by granuloma formation and the presence of interferon g (IFNg)-producing T cells that cause inflammation and tissue damage in multiple organs, especially the lung. Exosomes are nano-sized immunomodulatory vesicles of endosomal origin released from a diverse range of cells and are also found in physiological fluids i...

BACKGROUND Sarcoidosis is a systemic disease of unknown aetiology characterised by granuloma formation and the presence of interferon γ (IFNγ)-producing T cells that cause inflammation and tissue damage in multiple organs, especially the lung. Exosomes are nano-sized immunomodulatory vesicles of endosomal origin released from a diverse range of cells and are also found in physiological fluids i...
