The thyroid gland, anterior pituitary gland, and hypothalamus comprise a self-regulatory circuit called the hypothalamic-pituitary-thyroid axis.

Webb2 juni 2024 · Thyroxine Binding Globulin is the primary transport protein of thyroid hormones. There are two other transport proteins, transthyretin and albumin are two other molecules that are in higher concentrations in the serum that can bind T4, T3 and reverse T3 but they don’t have the same affinity or attraction power. WebbThe primary transport protein is thyroxine-binding globulin (TBG), which has high affinity but low capacity for T3 and T4. TBG normally carries about 75% of bound thyroid hormones. The other binding proteins are Thyroxine-binding prealbumin (transthyretin), which has high affinity but low capacity for T4 hereford hospital acute medical unit
