Genome-wide analysis of Foxp3 target genes in developing and mature regulatory T cells
Abstract
Transcription factor Foxp3 (forkhead box P3), restricted in its expression to a specialized regulatory CD4+ T-cell subset (T(R)) with a dedicated suppressor function, controls T(R) lineage development. In humans and mice, Foxp3 deficiency results in a paucity of T(R) cells and a fatal breach in immunological tolerance, causing highly aggressive multi-organ autoimmune pathology. Here, through genome-wide analysis combining chromatin immunoprecipitation with mouse genome tiling array profiling, we identify Foxp3 binding regions for approximately 700 genes and for an intergenically encoded microRNA. We find that a large number of Foxp3-bound genes are up- or downregulated in Foxp3+ T cells, suggesting that Foxp3 acts as both a transcriptional activator and repressor. Foxp3-mediated regulation unique to the thymus affects, among others, genes encoding nuclear factors that control gene expression and chromatin remodelling. In contrast, Foxp3 target genes shared by the thymic and peripheral T(R) cells encode primarily plasma membrane proteins, as well as cell signalling proteins. Together, our studies suggest that distinct transcriptional sub-programmes implemented by Foxp3 establish T(R) lineage during differentiation and its proliferative and functional competence in the periphery.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
