Assessment of Th17 cells in the colons of AhR^−/−T-cell recipients 14 days after transplant. (A) Schema for the analysis of T cells isolated from the colon and a representative histogram characterizing donor B6 or AhR T cells from the colon of B6D2 recipient mice 14 days posttransplant. (B) Total number of donor T cells from WT or AhR mice and the frequency of donor T cells on day 14 posttransplant. N = 8 recipient B6D2 mice per group receiving either WT or AhR^−/− T cells with WT TCD BM. Data were pooled from 2 separate experiments. FMO, fluorescence minus one controls.
