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: Th17 cells and their hallmark cytokine IL-17A were reported to be involved in the development of autoimmune orchitis and encephalomyelitis by impairing the integrity of the blood–testis and blood–brain barrier integrity and by inducing local inflammation. However, the role of IL17A in autoimmune thyroid disease is still debatable.The aim of our study was to estimate immunoexpression of IL-17A in the thyroid tissue of patients with...

Introduction and aim: Cytokines play a crucial role in modulating immune response in both Hashimoto’s thyroiditis (HT) and Graves’ disease (GD). They may contribute to drive the autoimmune response skewing toward the Th17 phenotype and away from Th1 or Th2 phenotypes. Recent studies revealed an essential role of Th17 cells and their cytokines in the development of autoimmune thyroid diseases (AITD). However, participation of Th17 cells in the pathogenesis of GD is ...

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...
