Why does Hashimoto's thyroiditis manifest when thyroglobulin is targeted?

💡 Explanation

Hashimoto's thyroiditis emerges from a failure in immune self-tolerance, particularly the regulatory T-cell function that normally suppresses autoreactive lymphocytes; because these T-cells fail, autoreactive T-cells attack thyroglobulin. Therefore, the immune system destroys thyroid tissue, rather than maintaining immune homeostasis.
