Sensitivity to Fas stimulation and exposure to synthetic ceramides. Normal and NPD lymphoblasts were incubated with 200 ng/ml of anti-Fas or control IgM (top), or with 25 μM C2-ceramide or C2-dihydroceramide (bottom). At different time points, the number of apoptotic cells was evaluated by propidium iodide staining and flow cytometry analysis. Results are expressed as mean ± SD of six different experiments.
