Project description:Regulatory T cells (Tregs) are responsible for limiting autoimmunity and chronic inflammation. Foxp3 is a transcription factor that acts as a master regulator of Treg development and function. A serendipitous observation led to the realization that a well-characterized Foxp3gfp reporter mouse, which expresses an N-terminal GFP-Foxp3 fusion protein, is a hypomorph that causes profoundly accelerated autoimmune diabetes on a NOD background. Although natural Treg development and in vitro function is not significantly altered in Foxp3gfp NOD and C57BL/6 mice, Treg fitness function in inflammatory environments is perturbed and TGF?-induced Treg development reduced. Foxp3gfpis unable to interact with the histone acetyltransferase Tip60, the histone deacetylase HDAC7, and the Ikaros family zinc finger 4, Eos, which leads to reduced Foxp3 acetylation and enhanced K48-linked polyubiquitylation. Collectively this leads to an altered transcriptional landscape and reduced Foxp3-mediated gene repression, notably at the hallmark IL-2 promoter. Loss of controlled Foxp3-driven epigenetic modification leads to Treg insufficiency that causes autoimmunity in prone environments. 16 samples overall split between 2 genotypes (wild type and Foxp3 knock in) and two cell types (Tregs and Tconv)

Project description:Analysis of Foxp3 ablated peripheral regulatory T cells. Regulatory T cells require the expression of the transcription factor Foxp3 for thymic development. It is not known whether continuous expression of Foxp3 is required for the maintained function of mature regulatory T cells in the periphery. Results indicate changes to the regulatory T cell developmental program in the absence of Foxp3. Experiment Overall Design: Compare Cre recombinase treated peripheral regulatory T cells possessing a Cre sensitive Foxp3 locus to Cre treated regulatory T cells with a wild type Foxp3 locus. Cre exposure is observed via the Cre sensitive expression of the yellow flourescent protein molecule.
