What are the target cells of thyroxine?
1 answer
The target cells of thyroxine (T4) are mainly the cells of tissues and organs throughout the body. Specifically, T4 acts on the nuclei of the cells to increase the rate of protein synthesis, stimulate the consumption of oxygen and glucose, and enhance the metabolism of lipids. T4 also regulates the growth and maturation of various tissues, including the brain, bone, and heart. Additionally, T4 helps to maintain the basal metabolic rate and increase the sensitivity of the body to catecholamines, such as adrenaline and noradrenaline.
