Dominant Th2 differentiation of human regulatory T cells upon loss of FOXP3 expression

ABSTRACT: CD4+CD25+FOXP3+ regulatory T cells (Treg) are pivotal for peripheral self-tolerance. They prevent immune responses to auto- and alloantigens and are thus under close scrutiny as cellular therapeutics for autoimmune diseases and the prevention or treatment of alloresponses after organ or stem cell transplantation. We previously showed that human Treg cells with a memory cell phenotype, but not those with a naïve phenotype, rapidly down-regulate expression of the lineage-defining transcription factor forkhead box P3 (FOXP3) upon in vitro expansion. We now compared the transcriptomes of stable FOXP3+ Treg and converted FOXP3- 'ex-Treg' cells by applying a newly developed intranuclear staining protocol that permits the isolation of intact mRNA from fixed, permeabilized and FACS-purified cell p
