It is well established that CD4(+)CD25(+) regulatory T cells (Tregs) inhibit autoimmune pathology. However, precisely how the behavior of disease-inducing T cells is altered by Tregs remains unclear. In this study we use a TCR transgenic model of diabetes to pinpoint how pathogenic CD4 T cells are modified by Tregs in vivo. We show that although Tregs only modestly inhibit CD4 cell expansion, they potently suppress tissue infiltration. This is associated with a failure of CD4 cells to differentiate into effector cells and to up-regulate the IFN-gamma-dependent chemokine receptor CXCR-3, which confers the ability to respond to pancreatic islet-derived CXCL10. Our data support a model in which Tregs permit T cell activation, yet prohibit T cell differentiation and migration into Ag-bearing tissues.
