B6 mice were treated with 100μg of anti-CD25 (PC61) or anti-GITR (DTA1) i.p. on days -1, 0, 5, and 7 in relation to BDL. On D8, livers were harvested and Thy1.2+ bulk T cells were isolated for confirmation of depletion or labeled with CFSE and co-cultured with allogeneic splenic DC. After 72-96 hours of co-culture, T cells were analyzed by flow cytometry to measure the (A) percentage of FoxP3+ cells among CD4 T cells remaining after depletion and (B) proliferation by CFSE dissolution. For proliferation data, the bar graphs show percentage of cells that divided. On the histograms, solid lines represent T cells stimulated with DC and the dashed lines unstimulated T cells. (C) IFNγ in supernatants from the anti-CD25 depletion experiment was analyzed by cytometric bead array confirm enhanced T cell function following Treg depletion. Data are representative of 3 independent experiments.
