Introduction: Recently, Th17 cells and their cytokines were identified to play an important role in the pathogenesis of thyroid autoimmunity. IL-23, produced by antigen presenting cells, is required for survival and differentiation of Th17 cells, and is known to guide T cells toward the Th17 phenotype. Its serum levels are increased in several autoimmune diseases, including Hashimoto’s thyroiditis (HT), however, the expression level of IL-23 within thyroid tissue assessed...

Introduction: Autoimmune thyroid diseases, including Graves’ disease (GD) and Hashimoto’s thyroiditis (HT), are complex diseases combining genetic susceptibility and environmental encounters leading to the breakdown of immune tolerance. The relationship between thyroid cancer (TC) and HT has been proven (Guarino et al. 2010), and the antibody specific association has been demonstrated (Azizi et al. 2014). Overexpression of claudin-1 appears to be an...
