The intracellular forkhead winged transcription factor Foxp3 (forkhead box P3) appears to be specifically expressed by naturally occurring Treg cells, particularly in mice, although in humans there is evidence of upregulation of Foxp3 in all T cells on activation. Foxp3 is required for the development and function of naturally occurring regulatory t cells (treg) and expression is sufficient to convert non-regulatory CD4+CD25T cells into cells with regulatory activity. Conversion of peripheral CD4+CD25 naive T cells to Foxp3+CD4+CD25 foxp3+ Treg cells can be induced by TGF-ß. In a murine asthma model, these TGF-ß-induced Treg prevented house-dust mite-induced allergic pathogenesis or infection pathogenesis in lungs. A single independent report has suggested that IL-4 and IL-13 also induce Foxp3+CD25+ Treg from CD4+CD25precursors. (more…)

Regulatory T cells Treg (picture above) is the existence of suppressor cells, which limit ongoing immune responses and prevent autoimmune disease, was postulated over 30 years ago. The recent phenotypic and functional characterization of these cells has led to a resurgence of interest in their therapeutic application in a number of immune-mediated diseases. Two broad subsets of CD3+CD4+ suppressive or Treg cells have been described: constitutive or naturally occurring versus adaptive or inducible Treg. (more…)
