Expression of activation markers on activated CD4 T cells treated with HDAC-i.
CD25 (A), CD154 (B), and CD69 (C) were measured by flow cytometry 24 hours after stimulation with 3 × 28 beads with or without the indicated amount of FR901228. Results are shown as mean fluorescence intensity (MFI) of gated CD4 T cells.
