Background: The incidence of AITDs increased with the increase of iodine nutrient levels in the population. HT is one of the most common AITDs. The role of thyroid function stratification, antibody titer, Th17/Treg cells and related factors in the pathogenesis of HT under different iodine nutritional conditions is still unclear. Objective: To investigate the correlation between the thyroid function stratification, autoantibody titer and Th17 cells, Treg cells, cytokines and transcription factors in hashimoto thyroiditis patients with different iodine nutritional status. Methods: Thyroid hormone, autoantibody and urinary iodine levels were measured in 100 hashimoto's thyroiditis (HT) patients and 60 healthy subjects by electrochemical immunoluminescence and iodine-catalyzed arseniummethod. Meanwhile, the proportion and ratio of Th17 cells and Tregs cells in peripheral blood mononuclear cells (PBMC) were determined by immunofluorescence labeling and flow cytometry. The qRT-PCR was used to detect the expression of ROR-γt mRNA and Foxp3 mRNA. Serum IL-17 and TGF-β levels were detected by ELISA. Results: Th17 cell proportion, serum IL-17 and ROR-γt mRNA expression levels in PBMC of HT patients with different iodine nutritional status were all higher than those in the control group (P<0.05), while Tregs cell proportion, serum TGF-β and Foxp3 mRNA level were all lower than those in the control group (P<0.05). Conclusions: The thyroid function, autoantibodies, Th17/Tregs cell proportion, cytokines and transcription factors of HT patients with different iodine nutrition status were changed, hich were involved in the development and progression of HT.
Background: PTPN22 is an important candidate gene for autoimmune diseases and its SNP is involved in the pathogenesis of a variety of autoimmune diseases. Objective: To investigate the relationship between the PTPN22 gene polymorphism (rs2488457) and the Th17 and Treg cells and factors in the peripheral blood mononuclear cells (PBMC) of Graves' disease (GD) patients with different iodine nutrition conditions. Methods: We selected 100 GD patients and 60 healthy people in Cangzhou Central Hospital and People's Hospital from September 2019 to August 2020 and used SASP-PCR technology to calculate the PTPN22-1123 genotype and allele frequency. Flow cytometrywere used to detect the ratio and ratio of Th17 and Treg cells in PBMC and real-time PCR were used to detect the mRNA expression levels of ROR-γt and Foxp3. ELISA method was used to detect serum IL-17 and TGF-β levels. Results: The PTPN22 gene -1123G>C (rs2488457) of GD patients has a certain correlation with Th17 and Treg cells and their factors in PBMC. The distribution frequencies of various genotypes and alleles were statistically different between GD patients and the control group (P<0.05), but they had nothing to do with iodine nutrition status. The C/G and C/C genotypes at the PTPN22 gene (1123 G>C) of may increase the risk of GD, while the G/G genotype may reduce the risk of GD. Conclusion: PTPN22 gene polymorphism (rs2488457) in GD patients and Th17 and Treg cells and their factors in PBMC are related to GD susceptibility.
Background: Research has shown that STAT gene SNP is related to the pathogenesis of T1D, SLE, RA and AITD.Objective: To investigate the correlation of the SNP of Th17/Treg cell and its cytokines with STAT4 in the PBMC of AITD patients with different iodine nutritious status. Method: 100 GD and HT patients who are selected from Cangzhou Central Hospital and Cangzhou People's Hospital from September 2019 to August 2020, respectively, 60 healthy cases, adopt flow cytometer and quantitative real-time PCR to test the Th17and Treg cell ratio and proportion in PBMC and the expression level of ROR-γt and 3 (Foxp3) mRNA, and use ELISA method to test IL-17 and TGF-β level in the serum. Utilize SASP-PCR technology to test SNP locus (rs7574865) of STAT4 gene, and calculate the genotype and allele frequency. Result: There is some correlation between Th17/Treg cell & its factors in PBMC in the AITD patients and STAT4 rs7574865; compared with healthy control group, the difference between STAT4 rs7574865 G/T &T/T genotype and G&T allele frequency is of statistic significance (χ2 is 6.128 and 5.613 respectively, and the average value of P is <0.05), and may increase the occurrence risk of AITD, but has no correlation with iodine nutritious status. Conclusion: AITD patients not only have Th17 and Treg cell imbalance and the corresponding factor changes but also correlate to STAT4 rs7574865 susceptibility, and the cellular immunity and gene SNP may participate in the disease occurrence process of AIDT together.
Objective: To investigate the correlation between thyroid function stratification and autoantibody titers in patients with Graves' disease (GD) under different iodine nutrition conditions. Methods: The levels of serum thyroid hormones, autoantibodies and urinary iodine in 100 patients with different thyroid function GD [GD-A, GD-B] and 60 healthy subjects are detected by electrochemical immunoluminescence and iodine-catalyzed arsenic-cerium method. Results: The proportion of GD patients with the sum of iodine overdosage and iodine overdosage group is consistent with iodine adequate group, which is significantly higher than iodine deficiency group, and the (Median Urine Iodine, MUI) of GD-A group is significantly higher than GD-B group. Urinary iodine levels in GD group and GD-A group are positively correlated with serum FT3 and FT4 (P<0.05), and negatively correlated with (thyroid stimulating hormone, TSH) (P<0.05). The levels of serum (thyroid peroxidase antibody, TPOAb) and (thyroid globulin antibody, TGAb) in each GD group are significantly higher than those in the control group. Serum TSH levels in the high TPOAb group and high TgAb group are lower than those in the low TPOAb group, low TgAb group and control group, respectively. The levels of FT3 and FT4 are higher than those of the low TPOAb group and the low TgAb group, however, there is no significant difference between the FT3 of low TgAb and T3 and T4 levels that belong to the control group, high TPOAb group, high TgAb group, low TPOAb group, and low TgAb group. In conclusion: GD patients with different thyroid functions have corresponding changes in their thyroid hormone and autoantibody levels under different iodine nutrition conditions, which indicates that iodine nutrition status involve in and play an important role in the development of GD with different thyroid functions and different antibody levels.
Introduction: At present, studies on the role of iodine nutrition in thyroid function stratification, antibody titer, Th17/Treg cells and related factors in the pathogenesis of GD have not been carried out. Objective: The acritical aims to investigate the correlation between thyroid function and autoantibody titers of Graves' disease (GD) patients with different iodine nutritional status with Th17/Treg cells, their cytokines and transcription factors, and the role of related factors in the pathogenesis of GD. Method: The levels of serum thyroid hormone, autoantibodies and urine iodine in 100 GD patients and 60 healthy subjects are detected by electrochemiluminescence instrument and iodine-catalyzed arsenic-cerium method, respectively. The ratio of Th17 cells to Treg cells and Th17/Treg ratio in peripheral blood mononuclear cells (PBMC) are detected by immunofluorescence-labeled monoclonal antibodies and flow cytometry. Real-time fluorescence quantitative PCR is used to detect the expression levels of retinoic acid-related orphan receptor (ROR-γt) and fork head/wing-shaped spiral transcription factor 3 (Foxp3) mRNA, and the serum IL-17 and TGF-β levels are detected by ELISA. Result: As a result, the proportion of Th17 cells, serum IL-17 and ROR-γt in PBMC of GD patients with different iodine nutritional status significantly increase, while the proportion of Treg cells, the expression of Foxp3mRNA and serum TGF-β significantly decrease. The ratio of Th17/Treg cells in GD patients is significantly positively correlated with the titers of TPOAb and TgAb, and the titers of TPOAb and TgAb antibodies are significantly correlated with Th17/Treg, IL-17 and ROR-γt. Conclusion: In conclusion, thyroid hormones, autoantibodies, Th17, Treg cell ratios and dysfunctions as well as corresponding cytokines and transcription factors in GD patients with different iodine nutritional status participate in the development of GD.
