DC are essential for presenting prostatic antigen during tumorigenesis. Pro-HA single transgenic and Pro-HA × TRAMP double transgenic mice on the B10.D2 background were lethally irradiated and reconstituted with bone marrow from either control NT or CD11c-DTR (DTR) donors. At least 8 week slater, chimeras were treated with DT(4ηg/gbody weight)or PBS on Days −4, −1, and +2, and received adoptive transfers of naœve CFSE-labeled clonotypic CD4 cells on Day 0 which were subsequently recovered for analysis 5 days post-transfer from the prostate-draining LN. Chimeric recipients were between 3 and 4 months of age at the time of adoptive transfer. Representative CFSE-dilution histograms (A) and scatter plot showing the percentage of clonotypic CD4 cells with diluted CFSE for individual mice(B)are presented as in previous figures.
