CTLA4Ig Improves Murine iTreg Induction via TGFβ and Suppressor Function In Vitro

Figure 4

The presence of CTLA4Ig does not interfere with cytokine release in vitro. Supernatant of in vitro Treg induction cultures was collected at different time points and analyzed for the change in cytokine expression. (a) CD4+ T cell cultures cultivated in the presence of TGFβ showed significant increase in the production of suppressive cytokine IL-10 and (b) a significant decrease in the production of inflammatory cytokine IL-17A. Data were obtained from cells cultivated in triplicates and are representative for 3 independent experiments; control indicates CD4 T cells stimulated with anti-CD3/CD28 in the presence of IL2. Mean values for optical density (OD) are shown; error bars indicate standard deviation. , , and .
