BACKGROUND: Apoptosis is a joint pathogenic process underlying autoimmune thyroid disease. Increased programmed cell death in thyrocytes causes hypothyroidism in Hashimoto's thyroiditis, whereas in Graves' disease infiltrating lymphocytes undergo apoptosis while thyrocytes appear to proliferate under protection of anti-apoptotic signals. The Fas/Fas ligand cascade represents a major pathway initiating apoptosis. Its role in autoimmunity is well studied and genetic polymorphisms in gene loci of Fas and its ligand have been shown to be associated with autoimmune diseases. OBJECTIVE: Due to the functional relevance of the Fas pathway in autoimmune thyroid disease we were interested in the possible contribution of polymorphisms in the Fas gene to the genetic risk of thyroid autoimmunity, which so far is mainly, but incompletely, attributed to the HLA DQ region and polymorphisms in the CTLA-4 gene. DESIGN: We genotyped Caucasian families with at least one offspring affected by Hashimoto's thyroiditis (n=95) and Graves' disease (n=109) for two Fas gene polymorphisms (g-670 G-->A in the promoter region, g-154 C-->T in exon 7). METHODS: Extended transmission disequilibrium and chi(2) testing were performed. RESULTS: Neither polymorphism alone (P=0.44 and P=0.70) nor the promoter/exon 7 haplotypes (P=0.86) were associated with Hashimoto's thyroiditis. No association with Graves' disease was observed for the promoter polymorphism (P=0.91) and exon 7 (P=0.65) or the promoter/exon 7 haplotypes (P=0.80). CONCLUSION: In summary, our data do not suggest any significant contribution of common genetic Fas variants to the genetic risk of developing Hashimoto's thyroiditis or Graves' disease.

AbstractChemokines can be divided into four categories: α, β, γ, and δ. Chemokine α is related to neutrophil chemotaxis. Chemokine β is correlated with adsorption of monocytes, basophils, and eosinophils. Chemokine γ is mainly a lymphocyte chemokine. Function of chemokine δ remains unclear. Chemokines α and β are primarily related to occurrence and development of autoimmune thyroid disease. This study reviews chemokines and their receptors that are related to Graves’ disease and Hashimoto’s thyroiditis.

Abstract Background Recent researches suggest that the CD160/HVEM/LIGHT/BTLA signaling pathway may contribute to the pathogeneses of autoimmune diseases, but the relationship between CD160 polymorphisms and autoimmune thyroid disease (AITD) has not been reported yet. This study aimed to evaluate the associations between CD160 polymorphisms and AITD. Methods A total of 1017 patients with AITD (634 Graves’ disease and 383 Hashimoto’s thyroiditis) and 856 unrelated healthy controls were recruited into our study. Odds ratios (ORs) with 95% confidence interval (95%CI) were calculated through logistic regression analyses. The CD160 SNPs were detected using Hi-SNP high-throughput genotyping. Results There was a statistically significant difference between Graves’ disease patients and the control group with respect to both the genotype distribution (P = 0.014) and allele frequency of rs744877 (P = 0.034). A significant association of CD160 rs744877 with AITD was observed before adjusted age and gender under a dominant model (OR = 0.79, 95%CI 0.66–0.95; P = 0.013) and an additive model (OR = 0.77, 95%CI 0.64–0.94, P = 0.008), and was also observed after adjusted age and gender under a dominant model (OR = 0.78, 95%CI 0.65–0.95; P = 0.011) and an additive model (OR = 0.76, 95%CI 0.63–0.93, P = 0.007). A significant association of rs744877 with Graves’ disease was observed under an allele model (OR = 0.84, 95%CI 0.71–0.98, P = 0.027), a dominant model (OR = 0.74, 95%CI 0.60–0.91; P = 0.005), and an additive model (OR = 0.72, 95%CI 0.58–0.90, P = 0.004). Multivariate logistic regression analyses suggested that the association remained significant after adjustment for age and gender. However, rs744877 was not related to Hashimoto’s thyroiditis. Furthermore, CD160 rs3766526 was not significantly related to either Graves’ disease or Hashimoto’s thyroiditis. Conclusion This is the first identification of the association of CD160 rs744877 with Graves’ disease. Our findings add new data to the genetic contribution to Graves’ disease susceptibility and support the crucial role of the CD160/HVEM/LIGHT/BTLA pathway in the pathogenesis of Graves’ disease.

Patients with autoimmune thyroid disease frequently have high affinity antibodies to thyroid peroxidase (TPO), although the role they play in disease pathogenesis is not known. We have previously prepared 37 monoclonal anti-TPO IgGκ Fab fragments from two patients with Hashimoto’s thyroiditis and demonstrated the similarity of these Fab sequences to those published previously, mainly derived from patients with Graves’ disease. In this paper, we describe epitope mapping of these Fabs using a previously characterized panel of murine monoclonal antibody (mAb) and show that the Fabs bind to two neighboring epitopes on native TPO. Although the epitope-mapping method differs from that used to characterize previously published TPO-reactive Fab sequences, it indicates a similarly restricted response to neighboring epitopes in both Graves’ disease and Hashimoto’s thyroiditis. The epitope mapping included mAb 47, which binds to a linear TPO peptide of known sequence in addition to native TPO. Although TPO-reactive Fab did not inhibit the binding of mAb 47, mAb 47 did inhibit the binding of Fab, indicating the likely site of the immunodominant region on native TPO. These results confirm the restricted nature of TPO antibody and further delineate the immunodominant region of native TPO as defined by the mAb.
