Abstract:
We examined whether a synthetic retinoid Am80 prevented the development of autoimmune thyroiditis in iodide-treated nonobese diabetic mice, an animal model of Hashimoto's thyroiditis (HT). Am80 (0, 0.1 or 1 mg/kg/day) was orally administered in feed during the 8-week iodide treatment. While iodide ingestion effectively induced thyroiditis, Am80 administration failed to interfere with thyroiditis development and serum anti-thyroglobulin antibody levels regardless of the dose of the retinoid. Splenic T cell numbers, splenocyte proliferation and interferon-γ production were decreased in the Am80-treated mice. Our data suggest that Am80 is not a candidate for use in the prevention of HT.

Synthesis and Regulation of Thyroid Hormones
Upon reaching the thyroid gland, TSH stimulates the follicular cells' active uptake of iodide ions from the blood. The ions diffuse to the apical surface of the cells and are oxidized to iodine. The iodine is then...
