Figure Lengend Snippet: ( A ) Comparison of heart allograft survival among WT C57BL/6J, Ccl19 Cre Ltbr fl/fl , and Ccl19 Cre Ltbr fl/fl recipients with FRC injections ( n = 7–9 mice/group). Graft survival data were combined from 3 independent experiments. ( B ) Representative images and comparison of CD3-, CD11b-, and collagen 1–stained heart allografts from WT C57BL/6J and Ccl19 Cre Ltbr fl/fl recipients ( n = 4 mice/group). Scale bars: 200 μm. ( C ) Flow cytometry analysis of DLNs from WT C57BL/6J and Ccl19 Cre Ltbr fl/fl recipients ( n = 4 mice/group). ( D ) Representative images and comparison of Foxp3-stained DLNs ( n = 4 mice/group). Scale bars: 200 μm. ( E ) Flow cytometry analysis of transferred TCR Tg cells in DLNs ( n = 4 mice/group). ( F ) Comparison of heart allograft survival among WT C57BL/6J recipients treated with anti-LTβR agonist mAb alone (20 μg i.v. on day 0), anti-CD40L alone (40 μg i.v. on day 0), and both anti-LTβR agonist mAb and anti-CD40L of BALB/c hearts ( n = 6 mice/group). Graft survival data were combined from 2 independent experiments. log-rank test for graft survival. Student’s t test for comparisons between 2 groups. Data are represented as means ± SEM. * P < 0.05; ** P < 0.01; *** P < 0.001; **** P < 0.0001.
Article Snippet: As the standard protocol in this study, anti-CD40L mAb (MR1, 125 μg i.v. on days 0 and 1, BioXCell, BE0017-1) or CTLA4-Ig (Abatacept, 500 μg i.p. on day 0 and 250 μg i.p. on days 2, 4, 6, 8, Bristol-Myers Squibb) was administered to recipient mice.
