Images of flow cytometric analysis for CD95, CD95L and HLA-DR expression on lymphocytes. (a) CD95 expression on CD4⁺ cells. (b) CD95L expression on CD8⁺ cells. (c) HLA-DR expression on CD8⁺ cells. (d) CD95 expression on either CD8⁺ HLA-DR⁻ or HLA-DR⁺ cells. (e) CD95L expression on either CD8⁺ HLA-DR⁻ or HLA-DR⁺ cells. (f) CD95L expression on B cells in monkey infected with C2/1. Mean fluorescence intensity (MFI) or percentage of the population is indicated in each histogram or dot image.
