Previously, we have shown that CD8(+)T/FOXP3(+) cell ratio but not FOXP3(+) cell number alone is an independent prognostic factor for colorectal cancer. In the present study, we evaluated whether the number of intratumoral FOXP3(+)VEGFR2(+) (itFOXP3(+)VEGFR2(+)) T cells alone could be a predictive factor for survival prognosis in patients with colorectal cancer. Distribution of regulatory T cel...
The forkhead, winged-helix transcription factor FOXP3 is preferentially expressed in T regulatory (Treg) cells and is critical for their immunosuppressive function. Mutations that abolish FOXP3 function lead to systemic autoimmunity in mice and humans. However, the manner by which FOXP3 recognizes cognate DNA elements is unclear. Here we identify an in vitro optimized DNA sequence to assess FOX...
Regulatory T cells are believed to control the development and progression of autoimmunity by suppressing autoreactive T cells. Decreased numbers of CD4(+)CD25(+) FOXP3(+) T cells (Tregs) are associated with impaired immune homeostasis and development of autoimmune diseases. The transcription factors FOXP3 and NFAT1 have key roles in regulatory T-cell development and function. We show that Treg...
The X-linked Foxp3 is a member of the forkhead/winged helix transcription factor family. Germline mutations cause lethal autoimmune diseases in males. Serendipitously, we observed that female mice heterozygous for the "scurfin" mutation of the Foxp3 gene (Foxp3(sf/+)) developed cancer at a high rate. The majority of the cancers were mammary carcinomas in which the wild-type Foxp3 allele was ina...
FoxP3 is a member of the forkhead/winged helix family of transcription factors and plays a critical role in the development and function of CD4+CD25+ regulatory T cells (Tregs). In this study, we performed an immunohistochemical evaluation of FoxP3-expressing cells in inflammatory bowel disease (IBD) mucosa. Mucosal FoxP3 expression was evaluated by immunohistochemistry in samples from normal (...
Objective: We aimed to evaluate the number and function of regulatory T (Treg) cells in peripheral blood prostate tissues patients with histopathologically diagnosed benign hyperplasia (BPH) asymptomatic chronic prostatitis.
 Material Methods: Blood histopathological data 19 (BPH=10, ACP=9) that underwent transurethral resection were evaluated. Treg cell count prostatic tissue flowcytometr...
INTRODUCTION Our previous study has reported that, in patients with untreated new-onset lupus (UNOL), there was an abnormal increase in the number of CD4+CD25-Foxp3+ T cells that correlated with disease activity and significantly decreased after treatment. However, little is known about the nature of this cell entity. The aim of this study was to explore the nature of abnormally increased CD4+C...
Forkhead box p3 (FOXP3) is known to program the acquisition of suppressive capacities in CD4(+) regulatory T cells (Treg), whereas its role in CD8(+) T cells is unknown. The current study investigates whether FOXP3 also acts as a Treg master switch in peripheral blood and tonsillar CD8(+) T cells. Single-cell analyses reveal the existence of a FOXP3(+)CD8(+) population in human tonsils, whereas...
BACKGROUND Naturally occurring thymus derived regulatory T cells (Tregs) are central in the maintenance of self-tolerance. The transcription factor FOXP3 is crucial for the suppressive activity of Tregs and is considered the most specific marker for this population. However, human non regulatory T cells upregulate FOXP3 transiently upon activation which calls for other means to identify the Tre...
