Follicular cellThyrotropic cellHypothyroidismThyroid hormone: The thyroid hormones, triiodothyronine (T3) and its prohormone, thyroxine (T4), are tyrosine-based hormones produced by the thyroid gland that are primarily responsible for regulation of metabolism. T3 and T4 are partially composed of iodine (see molecular model).HyperthyroidismReverse triiodothyronineFamilial dysalbuminemic hyperthyroxinemia: Familial dysalbuminemic hyperthyroxinemia is a type of hyperthyroxinemia associated with mutations in the human serum albumin gene.GoitreIodine deficiencyIodothyronine deiodinase: Iodothyronine deiodinases ( and ) are a subfamily of deiodinase enzymes important in the activation and deactivation of thyroid hormones. Thyroxine (T4), the precursor of 3,5,3’-triiodothyronine (T3) is transformed into T3 by deiodinase activity.Euthyroid sick syndromeSymptoms and signs of Graves' disease: Virtually all the symptoms and signs of Graves' disease result from the direct and indirect effects of hyperthyroidism, with exceptions being Graves' ophthalmopathy, goitre and pretibial myxedema (which are caused by the autoimmune processes of Graves' disease). These clinical manifestations are dramatic and involve virtually every system in the body.Riedel's thyroiditisThyroid cancerAutoimmune thyroiditisCongenital hypothyroidismLiver biopsyAutoantibody: An autoantibody is an antibody (a type of protein) produced by the immune system that is directed against one or more of the individual's own proteins. Many autoimmune diseases, (notably lupus erythematosus), are caused by such autoantibodies.Laser ablation of thyroid nodules: Laser ablation of thyroid nodules is a minimally invasive procedure indicated to treat benign thyroid lesions such as cold nodules or single nodules within a multinodular goiter. The technique consists in the destruction of the tissue by the insertion therein of optical fibers which convey the light energy, causing a complete and not reversible lesions necrosis.Thyroglobulin: Thyroglobulin (Tg) is a 660 kDa, dimeric protein produced by the follicular cells of the thyroid and used entirely within the thyroid gland. Thyroglobulin protein accounts for approximately half of the protein content of the thyroid gland.Sodium perchloratePrenatal nutrition: Nutrition and weight management before and during :pregnancy has a profound effect on the development of infants. This is a rather critical time for healthy fetal development as infants rely heavily on maternal stores and nutrient for optimal growth and health outcome later in life.TriiodideThyroidectomyPropylthiouracilTRH stimulation test: Prior to the availability of sensitive TSH assays, thyrotropin releasing hormone (TRH)Hormone receptor: A hormone receptor is a molecule that can bind to a specific hormone. Receptors for peptide hormones tend to be found on the plasma membrane of cells, whereas receptors for lipid-soluble hormones are usually found within the cytoplasm.Toxic nodular goiterHashimoto's encephalopathy: Hashimoto's Encephalopathy is a rare autoimmune disease associated with Hashimoto's thyroiditis. It was first described in 1966.Subacute thyroiditisMyxedemaEndemic goitrePlasmodium hermani: Plasmodium hermani is a parasite of the genus Plasmodium subgenus Huffia.
