Thymic epithelial cell differentiation, growth and function depend on the expression of the transcription factor Foxn1, however its target genes have never been physically identified. Using novel static and inducible genetic model systems and chromatin studies, we provide now a genome wide map of direct Foxn1 target genes for postnatal thymic epithelia and define the Foxn1 binding motif. We detail the function of Foxn1 in these cells and demonstrate that in addition to the transcriptional control of genes involved in the attraction and lineage commitment of T cell precursors, Foxn1 regulates the expression of genes involved in antigen processing and thymocyte selection. Thus, critical events in thymic lympho-stromal cross-talk and T cell selection are indispensably choreographed by Foxn1.
