Human lung carcinomas express Fas ligand.
To reach a clinically detectable size, neoplasms must be able to suppress or evade a host immune response. Activated T cells may enter apoptosis in the presence of Fas ligand (FasL) (1), and tissue expression of FasL has been shown to contribute to immune privilege in the eye and testis (2, 3). We have demonstrated that all human lung carcinoma cell lines tested (16 of 16) express a Mr 38,000 p...
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 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 کاملImmune response and myoblasts that express Fas ligand.
; daf-2(e1370) hermaphrodites at the nonper-missive temperature and examining cross progeny for dauer formation. The descendants of the cross progeny were also examined to ensure that the mutations were not unlinked, noncomplementing mutations. We also mapped many of the mutations by testing for linkage with unc-29, which maps near daf-16, or else with daf-16–linked restriction fragment length ...
متن کاملIn vivo inhibition of Fas ligand-mediated killing by TR6, a Fas ligand decoy receptor.
TR6, a member of the tumor necrosis factor (TNF) receptor superfamily, has recently been shown to bind to Fas ligand (FasL) and inhibit FasL-mediated cell killing in vitro. In the current study, we demonstrate that TR6 can block the lethal activity of FasL in multiple in vitro systems, and extend this finding to an in vivo model of hepatitis. The binding of human TR6 to human FasL was verified ...
