... and -9 as well as Bax, but reduced the levels of Bcl-2 in Jurkat T cells. The purified exosomes contained Fas ligand, and treatment with soluble Fas abrogated exosome-mediated Jurkat T cell apoptosis. Conclusions: Our data indicate that exosomes from kidney adenocarcinoma cells contain Fas ligand...

... of cytotoxic molecules on tumor-infiltrating lymphocytes before and after therapy. Methods: Immunofluorescence staining allowed the specific detection of Fas, Fas ligand (FasL), and tumor necrosis factor (TNF)-related apoptosis-inducing ligand (TRAIL) expression on tumor cells and the respective leukocyte...

... of Fas antigen in normal urothelium and TCC cell lines was measured by flow cytometry. The Fas/Fas ligand reaction-induced cytotoxic changes in tumor cells were evaluated by microculture MTT technique. The synergism efficacy of Fas-mediated apoptosis and TNF-α on adriamycin cytotoxicity of TCC cells...
