Measurement of mean fluorescence intensity (MFI). The MFI of TNFα release from (A) CD64+CD14+ monocytes, (B) CD11c+HLA-DRhi/low myeloid dendritic cells, (C) CD123+ plasmacytoid dendritic cells, and (D) CD3+ T lymphocytes from five discoid lupus erythematosus (DLE) and five dermatomyositis (DM) patients, as well as from five controls, as determined by flow cytometry. Bars show the means and SD. **
