Abstract
The function of regulatory T cells (Treg cells) has been attributed to a growing number of diverse pathways, molecules and processes. Seemingly contradictory conclusions regarding the mechanisms underlying Treg cell suppressive activity have revitalized skeptics in the field who challenge the core validity of the idea of Treg cells as central immune regulators. However, we note that a consensus may be emerging from the data: that multiple Treg cell functions act either directly or indirectly at the site of antigen presentation to create a regulatory milieu that promotes bystander suppression and infectious tolerance. Thus, the versatility and adaptability of the Foxp3+ Treg cells may in fact be the best argument that these cells are 'multitalented masters of immune regulation'.
