Figure Lengend Snippet: (A) Kaplan-Meier analysis of survival of B6 cardiac allografts in mice treated short or long term via intraperitoneal (i.p.) injection of GW4869 or vehicle (DMSO). Number of recipients and graft survival days are in parenthesis. (B) Representative analysis by ImageStream of recipient splenic APCs cross-dressed with donor H2Kb and H2Db, 2 days after transplantation of B6 CD45.1 cardiac allografts. CD63 colocalized in areas containing H2Kb H2Db. Magnification, X60, 40,000 cells. (C) Assessment by ImageStream of recipient total leukocytes and APCs cross-dressed with donor H2Kb and H2Db in splenocytes of BALB/c mice grafted with B6 CD45.1 hearts and treated with GW4869 or vehicle. Splenocytes of naïve BALB/c mice were included to set background (BKGD) staining (dotted lines). Each dot represents a mouse or graft recipient. No Tx, no transplant. (D) Flow cytometry analysis of division (CFSE dilution) and activation (CD44High) of CFSE-labeled T cell receptor transgenic 4C CD4 T cells, specific for IAd, in response to ex vivo stimulation with recipient (YFPPos) DCs FACS-sorted from spleens of CD11c-YFP B6 mice untreated (negative control) or grafted 3 days prior with BALB/c (H2d) hearts and treated with GW4869 or DMSO. Plots are representative of four transplants per group. (E) Effect of administration GW4869 or DMSO on DSA titers in serum of BALB/c mice grafted with B6 hearts. Each dot represents a mouse. Results in (C) and (E) were analyzed by one-way ANOVA, followed by Tukey-Kramer multiple comparison test. Error bars denote means ± SD. *P < 0.05, **P < 0.01, ***P < 0.001, and ****P < 0.0001.
