1 In vitro susceptibility of CD4+ and CD8+ T cell subsets to fludarabine. fludarabine CD4 molecule Homo sapiens
2 Administration of the adenosine analogue fludarabine (FLU) in vivo induces a profound and prolonged T lymphopenia which mainly affects CD4(+) cells. fludarabine CD4 molecule Homo sapiens
3 Administration of the adenosine analogue fludarabine (FLU) in vivo induces a profound and prolonged T lymphopenia which mainly affects CD4(+) cells. fludarabine CD4 molecule Homo sapiens
4 Contrasting with observations in vivo, our results showed that treatment of peripheral blood mononuclear cells with FLU induced a higher level of apoptosis in CD8(+) than in CD4(+) T lymphocytes. fludarabine CD4 molecule Homo sapiens
5 This increased sensitivity of CD8(+) T cells to FLU was observed in samples from both, healthy donors and B cell chronic lymphocytic leukemia patients, and resulted in higher CD4:CD8 ratios in FLU-treated than in untreated cultures (P<0.01). fludarabine CD4 molecule Homo sapiens
6 This increased sensitivity of CD8(+) T cells to FLU was observed in samples from both, healthy donors and B cell chronic lymphocytic leukemia patients, and resulted in higher CD4:CD8 ratios in FLU-treated than in untreated cultures (P<0.01). fludarabine CD4 molecule Homo sapiens
7 These results favor the view that decreased CD4:CD8 ratios in FLU-treated patients should be attributed to differences in cell recovery and/or homing between T cell subsets. fludarabine CD4 molecule Homo sapiens
