Figure 5: Phenotypic characterisation of putative CD25hi Foxp3+ Treg cells from cocultures of DC and naïve T cells. The CD25hi Foxp3+ population expresses CTLA-4 (a) but lacks expression of CD127 in comparison with control Foxp3- T cells (b), consistent with the reported phenotype of bona fide Treg cells.
