A study published in Nature reveals that the thymus gland plays a crucial role in regulating the immune system and metabolic control during pregnancy. The researchers found that female sex hormones instruct changes in the thymus to produce specialized cells called Tregs, which help prevent miscarriage and gestational diabetes.
Researchers found that the thymus produces Tregs specialized in dealing with physiological changes during pregnancy, preventing miscarriages. The study also shows that a deficiency of these cells leads to gestational diabetes and long-lasting effects on offspring.
A study found that the thymus produces specialized cells called 'Tregs' during pregnancy to deal with physiological changes. RANK, a receptor expressed in the thymus epithelium, is the key molecule behind this mechanism.
