FAS Ligand Triggers Pulmonary Silicosis
We investigated the role of Fas ligand in murine silicosis. Wild-type mice instilled with silica developed severe pulmonary inflammation, with local production of tumor necrosis factor (TNF)-alpha, and interstitial neutrophil and macrophage infiltration in the lungs. Strikingly, Fas ligand-deficient generalized lymphoproliferative disease mutant (gld) mice did not develop silicosis. The gld mic...
متن کاملExpression of Fas antigen and Fas ligand in bronchoalveolar lavage from silicosis patients.
OBJECTIVE To understand the role of apoptosis through Fas/Fas ligand (FasL) interaction in the pathogenesis of silicosis, we examined the expression of Fas antigen, FasL and apoptosis in bronchoalveolar lavage fluid lymphocytes obtained from patients with silicosis. MATERIALS AND METHODS Ten patients with silicosis, and 10 healthy controls were studied. Non-adherent cells were separated and a...
متن کاملStatus of FAS and FAS Ligand Gene Polymorphisms in Patients wi th Breast Cancer in Northeastern IRAN
Background: The First apoptosis signal (FAS) and First apoptosis signal ligand (FASL) genes initiate the apoptosis pathway, playing a central role in the tumor growth and metastasis. Gene polymorphisms including -1377 G/A in the promoter region of FAS and -844 C/T in the promoter region of FASL have shown to change the transcription activities of these genes. Methods: In this study we evalua...
متن کاملFas/Fas ligand pathway
The orphan nuclear receptor Nur77/N10 has recently been demonstrated to be involved in apoptosis of T cell hybridomas. We report here that chronic expression of Nur77/N10 in thymocytes of transgenic mice results in a dramatic reduction of CD4+CD8+ double-positive as well as CD4+CD8and CD4-CD8+ single-positive cell populations due to an early onset ofapoptosis. CD4-CD8double-negative and CD25+ p...
متن کاملThe Fas ligand/Fas system in renal injury.
The FasL-Fas system regulates renal cell apoptosis, as well as the immune and inflammatory responses. Evidence that FasL and Fas participate in renal injury may be summarized along modified Koch's postulates (Table 1): (i) FasL is expressed by renal cells and during renal injury, (ii) activation of the Fas receptor promotes apoptosis of cultured renal cells, (iii) Fas agonists induce glomerular...
