title: A novel modifier of regulatory T cells.
abstract: The receptor for the lipid mediator sphingosine 1-phosphate is critical for T cell trafficking. New data show that signaling mediated by this receptor critically controls the development, maintenance and suppressive activity of natural regulatory T cells that express the transcription factor Foxp3.
