OBJECTIVE: Hashimoto's Thyroiditis (HT) is an autoimmune disease, characterized by chronic inflammation of the thyroid gland with unknown etiologies. Recently, interleukin-33/ST2 (IL- 33/ST2) pathway reveals its participation in the process of several autoimmune diseases. In this study, the role of IL-33/ST2 pathway in the development of HT is investigated.

METHODS: The levels of plasma IL-33, sST2 and the frequency of circulating CD4+ST2L+T cells in 30 HT patients and 20 healthy controls were determined by enzyme-linked immunosorbent assay (ELISA) and flow cytometry respectively. The mRNA expressions of related molecules in IL-33/ST2 pathway in thyroid tissues (12 HT patients and 10 controls) were detected by real-time quantitative PCR (RTqPCR). The protein expressions of IL-33 and ST2 were determined by Western blot and immunohistochemistry staining.

RESULTS: The mRNA expressions of plasma IL-33 and sST2 were elevated in HT patients, with an increased ratio of IL-33/sST2. The number of CD4+ST2L+ T cells in PBMCs of HT group was significantly increased when compared to the control group (CON) by Flow cytometry assay. MRNA Expression of IL-33 and ST2 in thyroid tissue and the level of IL-1β and IL-18 were significantly upregulated in HT patients, while IL-5 was down-regulated in HT patients, compared to CON. The expression of IL-1β and IL-18 were positively correlated with the expression of IL-33. Results of western blot and immunohistochemical staining were consistent with qPCR.

CONCLUSION: IL-33/ST2 pathway participates in HT via affecting the production of inflammatory cytokines.
