Regulatory T cells (Tregs) fulfill a central role in immune regulation. We reported previously that the integrin {alpha}Eß7 discriminates distinct subsets of murine CD4+ regulatory T cells. Use of this marker has now helped to unravel a fundamental dichotomy among regulatory T cells. {alpha}E-CD25+ cells expressed L-selectin and CCR7, enabling recirculation through lymphoid tissues. In contrast, {alpha}E-positive subsets (CD25+ and CD25-) displayed an effector/memory phenotype expressing high levels of E/P-selectin–binding ligands, multiple adhesion molecules as well as receptors for inflammatory chemokines, allowing efficient migration into inflamed sites. Accordingly, {alpha}E-expressing cells were found to be the most potent suppressors of inflammatory processes in disease models such as antigen-induced arthritis.

Key Words: CD103 • CD25 • lymphocyte migration • chemokines • inflammation
