Specification of Treg cells: learning from FoxP3 deficiencies
T regulatory (Treg) cells help maintain immunologic tolerance and control inflammation in many contexts. Their dysfunction leads to multi-organ autoimmunity in FoxP3-deficient mice and human IPEX patients, with variable clinical manifestations. Treg function and homeostasis are dependent on the transcription factor FoxP3, encoded on ChrX, which determines a substantial portion of their specific transcriptome. Our prior work on FoxP3 structure/function explored how FoxP3’s interactions with different cofactors within multimolecular complexes that reside in different nuclear compartments, and condition its transactivating potential on different transcriptional targets. Further, single-cell…
