GD Tregs exhibited weaker suppressive activity, miR-23a-3p mimic suppressed SIRT1 expression and suppressive-activity of Tregs whereas it promoted the expression and acetylation level of FOXP3 in the GD group.
Without rhIL-21 stimulation, the expression levels of retinoid-related orphan gamma t (RORγt), IL-17, IL-22, forkhead box protein P3 (Foxp3) and IL-10 mRNA and the IL-10 and IL-22 proteins were significantly higher in the GD group than those in the eGD and control groups (<i>P</i> < 0.05). rhIL-21 stimulation increased the RORγt, IL-17, and IL-22 mRNA levels and IL-22 protein levels and decreased the Foxp3 and IL-10 mRNA levels and IL-10 protein levels (<i>P</i> < 0.05) in the GD group.
Based on previous studies of early-onset GD, 11 single nucleotide polymorphisms (SNPs) and their related SNPs (R<sup>2</sup> > .6), SNPs located within a ±1-Mb region of the FOXP3 gene, and 20 validated GD-risk SNPs were selected and screened for genotyping in 3735 GD and 4893 control patients to investigate whether early-onset GD is a subtype of GD with distinct susceptibility genes.
Decreased Frequencies of Peripheral Blood CD4+CD25+CD127-Foxp3+ in Patients with Graves' Disease and Graves' Orbitopathy: Enhancing Effect of Insulin Growth Factor-1 on Treg Cells.
The proportions of Tregs and Bregs as well as the Foxp3 gene expression but not IL-10 were significantly decreased in GD group compared with the healthy controls.
To investigate the association between Foxp3 gene polymorphisms and the susceptibility to Graves' disease (GD) in Chinese Han population, four single nucleotide polymorphisms (SNPs) including -2383, -3279, -3499 in the promoter and IVS9+459 in the intron were genotyped.
The aim of our study was to estimate the association of three polymorphism of FOXP3 gene with the predisposition to Graves' disease (GD) and Hashimoto's thyroiditis (HT) in children and adolescents.
Because a single nucleotide polymorphism (SNP) within the FoxP3 gene (rs3761548 in the promoter region) is associated with susceptibility to Graves' disease, this study detected rs3761548 in a hospital-based case-control study.
The proportion of Treg cells and the transcription factor forkhead box P3 (FOXP3) mRNA expression in PBMCs decreased in GD patients compared with healthy subjects, and Treg cell function was impaired in patients with GD.
The -3279CA genotype was more frequent in patients with GD in remission than in patients with intractable GD, and the -3279AA genotype, which correlates to defective transcription of FOXP3, was absent in patients with GD in remission.
We have identified four subset-specific AITD loci, and two putative subset-specific AITD susceptibility genes; the FOXP3 gene in juvenile GD and the thyroglobulin gene in females with AITD.
