New Research on Triiodothyronine (T3) and its Effects on the Immune System

Research Triiodothyronine

and Health

Recent research on Triiodothyronine (T3) has shed some light on the influence it has on the immune system and health. T3 is one of the two hormones released by the thyroid gland and its production is regulated by the hypothalamic-pituitary-thyroid axis (HPT).

What is Triiodothyronine (T3)?

Triiodothyronine (T3) is an important hormone in the body which contributes to the regulation of several processes. It is present in all cells and plays an essential role in the body’s metabolic rate, the conversion of T4 (thyroxine) to its active form (T3), and the regulation of calcium levels.

Recent Research on T3:

Recent research has found that T3 has a direct effect on immune cells, influencing the production of cytokines and chemokines, which are molecules involved in the modulation of the immune response. Studies have also found that T3 can modulate the inflammation of various types of cells.

Effects of T3 on the Immune System and Health:

T3 has been found to be vital for the health of the immune system. Higher levels of T3 can lead to an improved immune system, as well as an increased number of immune cells. Additionally, T3 has been linked to improved cell-mediated responses, which can help fight infections.

Research has also found that T3 has a beneficial effect on overall health. T3 has been linked to decreased risk for disease, improved heart health, and improved cognitive functioning. T3 also plays a role in determining how the body deals with stress, and can lead to improved mood and mental clarity.


Recent research has provided insight into the role and importance of T3 in the human body. T3 is essential for the proper functioning of the immune system, as well as overall health. Further research is needed to better understand the mechanisms of T3 and its effects on the body.
