Alteration of T helper cell subsets in the optic nerve of experimental autoimmune encephalomyelitis.
The objective of this study was to detect interleukin-17 (IL-17), interferon-gamma (IFN-gamma), interleukin-4 (IL-4) and forkhead/winged helix transcription factor p3 (Foxp3) protein and gene expression of the optic nerve and to further explore the role of T helper cell subsets such as Th1, Th2, Th17 and Treg in the pathogenesis of optic neuritis in experimental autoimmune encephalomyelitis (EA...
Regulatory T-cells (Treg) play an essential role in the negative regulation of immune answers by developing an attenuated cytokine response that allows suppressing proliferation and effector function of T-cells (CD4(+) Th). The transcription factor FoxP3 is responsible for the regulation of many genes involved in the Treg gene signature. Its ablation leads to severe immune deficiencies in human...
Human T-cell leukemia virus type 1 (HTLV-1) is an oncogenic retrovirus that is etiologically associated with adult T-cell leukemia. The HTLV-1 bZIP factor (HBZ), which is encoded by the minus strand of the provirus, is involved in both regulation of viral gene transcription and T-cell proliferation. We showed in this report that HBZ interacted with Smad2/3, and enhanced transforming growth fact...
Maintaining immune tolerance requires the production of Foxp3-expressing regulatory T (Treg) cells in the thymus. Activation of NF-κB transcription factors is critically required for Treg cell development, partly via initiating Foxp3 expression. NF-κB activation is controlled by a negative feedback regulation through the ubiquitin editing enzyme A20, which reduces proinflammatory signaling in m...
UNLABELLED The aim of this study was to examine the interaction of Notch/Notch ligand with Th17/Treg, cytokines IL-35 and IL-17 in cases of preeclampsia (PE). METHODS Peripheral blood was obtained from 42 PE patients and 22 health pregnant women. The mRNA expressions of Notch/Notch ligand, Treg transcription factor FoxP3 and Th17 transcription factor RORγt, EBI3 and P35 (IL-35 two subunits), ...
Defective expression of LATS2, a negative regulator of YAP oncoprotein, has been reported in cancer of prostate, breast, liver, brain, and blood origins. However, no transcriptional regulators for the LATS2 gene have been identified. Here we report that spontaneous mutation of the transcription factor FOXP3 reduces expression of the LATS2 gene in mammary epithelial cells. shRNA-mediated silenci...
FOXP3 is inactivated in breast cancer cells by a number ofmechanisms, including somatic mutations, deletion, andepigenetic silencing. Because the mutation and deletion areusually heterozygous in the cancer samples, it is of interestto determine whether the gene can be induced for thepurpose of cancer therapy. Here, we report that anisomycin,a potent activator of activati...
Correlation of Local FOXP3-Expressing T Cells and Th1-Th2 Balance in Perennial Allergic Nasal Mucosa
Regulatory T cells (Treg) play some important roles in allergic rhinitis. The most specific marker for Treg is FOXP3, a recently identified transcription factor that is essential for Treg development. In order to clarify the levels of Treg in allergic nasal mucosa, we studied the relationship between FOXP3-expressing cells and Th1-Th2 balance in nasal mucosa by means of immunohistochemistry. Hu...
