Maintenance of lymphoid homeostasis in a number of immunological and inflammatory contexts is served by a variety of regulatory T (Treg) cell subtypes, and depends on interaction of the transcription factor Foxp3 with specific transcriptional cofactors. We report that a commonly used insertional mutant of FoxP3 (GFP-Foxp3) modified its molecular interactions, blocking Hif1a but increasing Irf4 interactions. The transcriptional profile of these Treg cells was subtly altered, with an over-representation of Irf4-dependent transcripts. In keeping with Irf4-dependent function of Treg cells to preferentially suppress T cell help to B cells and Th2- and Th17-type differentiation, GFP-Foxp3 mice showed a divergent susceptibility to autoimmune disease; protection against antibody-mediated arthritis in the K/BxN model, but greater susceptibility to diabetes on the NOD background. Thus, specific sub-functions of Treg cells and the immune diseases they regulate can be influenced by FoxP3’s molecular interactions, which result in divergent immunoregulation.
