Thymic epithelial cells provide unique cues for the life-long selection and differentiation of a repertoire of functionally diverse T cells. Rendered miRNA deficient, these stromal cells in the mouse lose their capacity to instruct the commitment of haematopoietic precursors to a T cell fate, to effect thymocyte positive selection and to achieve promiscuous gene expression required for central tolerance induction. Over time, the microenvironment created by miRNA-deficient thymic epithelia assumes the cellular composition and structure of peripheral lymphoid tissue where thympoiesis fails to be supported. These findings emphasize a global role for miRNA in the maintenance and function of the thymic epithelial cell scaffold and establish a novel mechanism how these cells control peripheral tissue antigen expression to prompt central immunological tolerance.
