Foxp3+ regulatory T (Treg) cells are essential for preventing autoimmunity and uncontrolled inflammation, and also modulate immune responses during infection and development of cancer. Accomplishing these tasks requires the widespread distribution of Treg cells in both lymphoid and non-lymphoid tissues, and the selective recruitment of Treg cells to different tissue sites has emerged as a key checkpoint that controlling tissue inflammation in autoimmunity, infection, cancer development and in the context of allograft acceptance or rejection. Additionally, Treg cells are functionally diverse, and it has become clear that some of this diversity segregates with Treg cell localization to particular tissue sites. In this article, I will review progress in understanding the mechanisms of Treg cell trafficking, and discuss factors controlling their homeostatic maintenance and function in distinct tissue sites.
