The Hypothalamic Pituitary Thyroid (HPT) axis is well-known as a classic endocrine negative feedback loop: increased levels of thyroxine (T4) in the blood are associated with a reduction of thyroid stimulating hormone (TSH) production and vice versa. However, the thyroid hormone (TH) system is sensitive to alterations by a number of endocrine disrupting chemicals (EDCs). Intriguingly, exposure to specific EDCs can decrease the levels of T4 but this might be not followed by the...

The Hypothalamic Pituitary Thyroid (HPT) axis is well-known as a classic endocrine negative feedback loop: increased levels of thyroxine (T4) in the blood are associated with a reduction of thyroid stimulating hormone (TSH) production and vice versa. However, the HPT axis is sensitive to alterations by a number of endocrine-disrupting chemicals (EDCs). Exposure to specific EDCs can deregulate the negative feedback loop and alter the TH/TSH levels. The intrinsic mechanisms for ...
