Stat6 decoy inhibits IL-4–inducible cell proliferation on a TH2 cell line and human CD4+ T cells.
Quiescent D10 cells (upper and middle panel) or human CD4+T cells (lower panel) (50 × 103/well) were transfected with Stat6 decoy or scrambled decoy ODN for 6 hours and cultured in 200 μL of growth media in the presence of IL-4 (▪, upper and lower panel) or IL-2 (▪, middle panel) or their absence (▨) for 16 hours at 37°C. Cells were then pulsed with [3H]-thymidine (0.5 μCi/200 μL) for an additional 4 hours and incorporation of radiolabeled probe plotted on the abscissa (expressed as total cpm for 6 samples).
