  • 简介:AbstractObjective:To analyze the proportion of peripheral regulatory T cells (Tregs) and the expression of the immune checkpoint molecules T-cell immunoglobulin and ITIM domain (TIGIT) and CD226 on Tregs in patients with recurrent spontaneous abortion (RSA).Methods:The proportion of CD3+CD4+CD25+Foxp3+ Tregs and the expression levels of CD226 and TIGIT on Tregs in 30 normal pregnant women and 28 patients with RSA were determined via flow cytometry.Results:The proportion of Tregs in the RSA group (4.41 % ± 1.54%) was significantly lower than that in the control group (5.27% ± 1.52%, P = 0.0374). Compared with the normal pregnant women, patients with RSA showed decreased TIGIT expression (54.75 ± 9.70% vs. 63.07 ± 12.48%, P = 0.0066) and increased CD226 expression on Tregs (25.59% ± 8.22% vs. 20.46% ± 6.97%, P = 0.0168). The ratio of CD226 to TIGIT in the RSA group (0.48 ± 0.19) was higher than that in the control group (0.34 ± 0.15, P = 0.0027). The proportion of TIGIT+CD226+ Tregs was significantly lower in patients with RSA (9.30% ± 4.95% vs. 13.43% ± 4.72%, P = 0.0020) than in the controls.Conclusions:Patients with RSA show a reduced proportion of Tregs and an imbalance in the expression of TIGIT and CD226 on Tregs.

  • 简介:AbstractBackground:Pancreatic adenocarcinoma (PAAD) is an extremely lethal malignancy. Identification of the functional genes and genetic variants related to PAAD prognosis is important and challenging. Previously identified prognostic genes from several expression profile analyses were inconsistent. The regulatory genetic variants that affect PAAD prognosis were largely unknown.Methods:Firstly, a meta-analysis was performed with seven published datasets to systematically explore the candidate prognostic genes for PAAD. Next, to identify the regulatory variants for those candidate genes, expression quantitative trait loci analysis was implemented with PAAD data resources from The Cancer Genome Atlas. Then, a two-stage association study in a total of 893 PAAD patients was conducted to interrogate the regulatory variants and find the prognostic locus. Finally, a series of biochemical experiments and phenotype assays were carried out to demonstrate the biological function of variation and genes in PAAD progression process.Results:A total of 128 genes were identified associated with the PAAD prognosis in the meta-analysis. Fourteen regulatory loci in 12 of the 128 genes were discovered, among which, only rs4887783, the functional variant in the promoter of Ring Finger and WD Repeat Domain 3 (RFWD3), presented significant association with PAAD prognosis in both stages of the population study. Dual-luciferase reporter and electrophoretic mobility shift assays demonstrated that rs4887783-G allele, which predicts the worse prognosis, enhanced the binding of transcript factor REST, thus elevating RFWD3 expression. Further phenotypic assays revealed that excess expression of RFWD3 promoted tumor cell migration without affecting their proliferation rate. RFWD3 was highly expressed in PAAD and might orchestrate the genes in the DNA repair process.Conclusions:RFWD3 and its regulatory variant are novel genetic factors for PAAD prognosis.

  • 简介:Xenogeneic胸腺移植能高效地在athymic接受者导致特定的有免疫力的忍耐到施主抗原。然而,许多裸体老鼠在xenogeneic胸腺移植以后患自体免疫的疾病(帮助)超过10个星期。CD4+CD25+Foxp3+规章的T(Treg)房间最近决心在在人和老鼠使忍耐有免疫力起一个枢轴的作用。因此,我们在受不了的老鼠帮助的猪胸腺接枝裸体的圆周调查了Treg房间的这subpopulation。我们的结果证明鼠标CD4+CD25+T房间和到CD4+T房间的CD4+CD25+Foxp3+Treg房间的比率上的Foxp3,CTLA-4和GITR的表达式显著地在受不了的鼠标帮助的猪胸腺接枝裸体的圆周被减少,与健康的猪或鼠标胸腺接枝裸体人鼠标相比。而且,在受不了的老鼠帮助的猪胸腺接枝裸体的老鼠CD4+CD25+T房间在xenogeneic与对应物相比在抑制免疫力的功能显示出更多的严重缺乏猪或syngeneic胸腺接枝裸体人老鼠没有帮助。因此,减少的频率,改变的显型和在猪胸腺接枝裸体人鼠标的鼠标CD4+CD25+Treg房间的功能的缺乏可以在这个模特儿贡献帮助的开发。
