Biological functions of thyroid hormone in placenta

Area of Science:

• Endocrinology
• Reproductive Biology
• Immunology

Background:

• Thyroid hormone (3,3,5-triiodo-L-thyronine, T3) regulates critical physiological processes, including inflammation.
• Infection and inflammation are key factors in placental development and pregnancy complications, with infection being a major cause of neonatal morbidity.
• The inflammasome, a multiprotein complex, plays a significant role in placental function and inflammation.

Purpose of the Study:

• To review current knowledge on thyroid hormone receptor-regulated inflammation in the placenta.
• To identify potential biomarkers and therapeutic targets for placental disorders.
• To elucidate the physiological significance of these mechanisms in pregnancy.

Main Methods:

• Literature review of studies on thyroid hormone, inflammasome, and placental function.
• Analysis of molecular mechanisms linking thyroid hormone signaling to inflammatory pathways in the placenta.
• Synthesis of information on potential biomarkers for pregnancy-related diseases.

Main Results:

• Thyroid hormone modulates inflammatory processes relevant to placental development.
• The inflammasome complex is implicated in placental health and disease.
• Elucidation of thyroid hormone's role in regulating inflammation-related molecules is crucial.

Conclusions:

• Understanding thyroid hormone receptor-regulated inflammation in the placenta is vital for advancing reproductive health.
• Novel predictive and therapeutic targets for placental disorders, including pre-eclampsia and infections, can be identified.
• Further research into placental biomarkers is needed for improved diagnosis and management.
