"Natural" regulatory T cells (nTregs) that express the transcription factor Foxp3 and produce IL-10 are required for systemic immunological tolerance. "Induced" regulatory T cells (iTregs) are nonredundant and essential for tolerance at mucosal surfaces, yet their mechanisms of suppression and stability are unknown. We investigated the role of(More)
CD4(+) CD25(+) Foxp3(+) regulatory T (Treg) cells are essential to the balance between pro- and anti-inflammatory responses. There are two major subsets of Treg cells, "natural" Treg (nTreg) cells that develop in the thymus, and "induced" Treg (iTreg) cells that arise in the periphery from CD4(+) Foxp3(-) conventional T cells and can be generated in vitro.(More)
To study regulatory T (Treg) cell control of chronic autoimmunity in a lymphoreplete host, we created and characterized a new model of autoimmune lung inflammation that targets the medium and small airways. We generated transgenic mice that express a chimeric membrane protein consisting of hen egg lysozyme and a hemoglobin epitope tag under the control of(More)
Purpose Regulatory T (Treg) cells are an essential subset of CD4+ T cells that induce and maintain immunological tolerance. Preclinical animal models have demonstrated that adop-tive transfer of Treg cells can prevent or cure diabetes, multiple sclerosis (EAE), inflammatory bowel disease, lupus, arthritis, and graft versus host disease.
