Thyroid hormone levels are strongly affected by inflammation. In a wide spectrum of diseases, ranging from critical illness in the ICU to ischemic stroke, a decrease in circulating T3 and T4 is observed without the expected increase in TSH. This disruption of the negative feedback system of the hypothalamic–pituitary–thyroid (HPT) axis is accompanied by various changes in thyroid hormone metabolism at the cellular and tissue level. C...

Thyroid hormone plays a critical role in the production and maintenance of myelin, the lipid-rich sheath that surrounds the outer surface of axons. Myelin is made from processes that extend from oligodendrocytes (OL), a glia cell that comprises about 20% of the cells in the adult central nervous system (CNS). Mature, myelinating OL are produced from a differentiation pathway that begins with neural stem cells and involves the differentiation of oligodendrocyte progenitor cells...
