Foxp3+ regulatory T (TR) cells limit pathogenic immune responses to self and foreign antigens. An essential role for microRNA (miRNA) in the maintenance and function of TR cells, revealed by the TR-specific Dicer ablation, raised a question as to a specific miRNA contribution. We found that Foxp3 controls the elevated miR155 expression required for maintaining TR proliferative activity and numbers under non-lymphopenic conditions. Moreover, miR155 deficiency in TR cells results in increased SOCS1 expression accompanied by impaired STAT5 activation in response to limiting amounts of IL-2. Our studies suggest Foxp3-dependent regulation of miR155 maintains competitive fitness of TR subset by targeting SOCS1, and provide an experimental support for a proposed role for miRNAs in ensuring the robustness of cellular phenotypes.
