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

Figure 2

CTLA4Ig enhances the proportion of induced Tregs in vitro. (a) Representative histograms of Treg markers are shown for different culture conditions (gated on total leucocytes). CD4+CD25+ T cells were analyzed (b) for the expression of FoxP3 (indicating induction of regulatory phenotype) by intracellular FACS staining after 6 days of in vitro culture ± CTLA4Ig and (c) Treg-associated markers CTLA4 and CD62L, which were analyzed and compared between groups. Cells were plated in triplicates for each culture condition. Data are representative for 3 independent experiments; control indicates CD4 T cells stimulated with anti-CD3/CD28 in the presence of IL2. Error bars represent standard deviation. , , and .
