Figure Lengend Snippet: a Splenic lymphocytes from C57BL/6 mice were treated with M290-MC-MMAF at the indicated concentrations for 48 h. The cells were subjected to multicolor FACS analyses using mAbs specific for CD3, CD4, and CD8. Data shown are the mean ± SD, n = 4 independent experiments. b Splenic lymphocytes from C57BL/6 mice were cultured with M290-MC-MMAF at the indicated concentrations for 32 h. FACS analyses were performed to determine the apoptosis/death of the CD4 + and CD8 + compartments using a Dead Cell Apoptosis Kit. Live cells, apoptotic cells, and dead cells are indicated. The data shown are representative of at least three independent experiments. c After stimulation with ConA (4 μg/ml) and treatment with M290-MC-MMAF at the indicated concentrations for 48 h, the proliferation of viable CD4 + or CD8 + compartments was determined. The CFSE low population indicates proliferating cells. Data are the mean ± SD, n = 5 independent experiments. * P < 0.05, ** P < 0.01, one-way ANOVA with Tukey’s multiple comparisons test

Figure Lengend Snippet: Diabetic C57BL/6 recipients were transplanted with BALB/c islets and treated with three doses of M290-MC-MMAF (3 mg/kg i.p. injected) or the indicated controls on days 1, 3, and 5 post transplantation. a Blood glucose was monitored every other day post transplantation. The dashed line at 200 mg/dl is considered the threshold for allograft rejection. b Kaplan−Meier plots for graft survival. Graft survival was compared using the log-rank test (*** P = 0.0001 vs. untreated). c Two M290-MC-MMAF-treated recipients developed hyperglycemia after removal of the graft on days 55 and 60 post transplantation

Figure Lengend Snippet: CD8 + T cells from CD103-depleted C57BL/6 mice (treated with M290-MC-MMAF) ( a ) or WT ( b , c ) were adoptively transferred into long-surviving recipients (>60 days). Donors were intraperitoneally immunized with 1× 10 7 BALB/c splenocytes 4 days before cell isolation. Each line represents blood glucose levels from a single recipient mouse. CD8 + cells for these experiments were enriched by immunomagnetic beads. d An anti-CD25 mAb (PC-61; 500 μg) was i.p. injected into the long-surviving recipient mice (>60 days) to deplete CD25 + CD4 + Tregs. Recipients were treated with rat IgG or PBS as a control. The Kaplan−Meier curve was plotted for graft survival. Graft survival was compared using the log-rank test (** P < 0.01 vs. PBS control)
