The forkhead DNA-binding protein FOXP3 is critical for the development and suppressive function of CD4(+)CD25(+) regulatory T cells (T(REG)), which play a key role in maintaining self-tolerance. Functionally, FOXP3 is capable of repressing transcription of cytokine genes regulated by NFAT. Various mechanisms have been proposed by which FOXP3 mediates these effects. Using novel cell lines that i...
Regulatory T cells (Tregs) play a critical role in maintaining immune tolerance and preventing autoimmune disease. Tregs express the transcription factor Foxp3, which acts as a master regulator of their differentiation and controls their capacity to suppress T cell responses. Tregs have an intrinsically anergic phenotype and do not produce IL-2 or proliferate upon stimulation ex vivo. Recent st...
background: pomegranate fruit (punica granatum l.) is a rich source of anthocyanin pigments resulting in vibrant colours and anti-oxidant contents. although the intensity and pattern of anthocyanin biosynthesis in fruit are strongly influenced by r2r3-myb transcription factors, little is known about the regulation and role of myb in anthocyanin pathway of pomegranate.objectives: the present stu...
Naive CD4 T cells activated by antigen-presenting cells (APCs) undergo terminal differentiation in the periphery. Multiple mechanisms determine their fates, that is, whether they differentiate into conventional T (Tconv) cells or regulatory T (Treg) cells. The key event during Treg generation is expression of the transcription factor Foxp3, which is the lineage-determining regulator for Treg di...
Regulatory T cells (Treg) that express the transcription factor Foxp3 are enriched within a broad range of murine and human solid tumors. The ontogeny of these Foxp3 Tregs - selective accumulation or proliferation of natural thymus-derived Treg (nTreg) or induced Treg (iTreg) converted in the periphery from naïve T cells - is not known. We used several strains of mice in which Foxp3 and EGFP ar...
PURPOSE The evaluation of CD3(+) T-cell density is believed to have a higher prognostic value than the conventionally used TMN stage in colorectal cancer (CRC), but the role of regulatory T lymphocytes (Treg) is still debated. Our study determined the prognostic value of forkhead box P3 nuclear transcription factor (FOXP3) positive Treg and CD3(+) T-cells in the invasive margin of CRC compared ...
