Dear Editor, Case 1 was a 41-year-old man with history of primary hyperthyroidism. At the time diagnosis, thyroglobulin antibodies were elevated although no thyrotropin receptor (TRAB) available. The patient treated carbimazole for 20 months. cessation in May 2020, thyroid function and TRAB levels

Trace amine-associated receptor 1 (Taar1) has been suggested as putative receptor of thyronamines. These are aminergic messengers with potential metabolic and neurological effects countering their contingent precursors, the thyroid hormones (THs). Recently, we found Taar1 to be localized at the primary cilia of rodent thyroid epithelial cells in vitro and in situ. Thus, Taar1 is present in a lo...

A great deal of circumstantial evidence has linked iodine with the rising incidence of autoimmune thyroiditis in the United States. In our investigations, we have shown directly that T cells from humans with chronic lymphocytic thyroiditis proliferate in the presence of iodinated but not in the presence of noniodinated human thyroglobulin. Moreover, the proliferative response is restored when t...

We describe a reliable and convenient double-antibody radioimmunoassay for human thyroglobulin that can be performed within two days. Analytical recoveries were quantitative and immunological equivalence between several sources of human thyroglobulin was demonstrated. Cross reactivity with either thyroxine or triiodothyronine was insignificant. The between-day coefficient of variation in the 5-...

We have isolated the entire gene for rat thyroglobulin, the precursor for thyroid hormone biosynthesis. The gene is at least 170,000 base pairs (bp) long; 9000 bp of coding information are distributed in 42 exons of homogeneous size (150-200 bp) except for two exons of 1100 and 620 bp. The sequences coding for two major thyroxine-forming sites are localized in exons 2 and 39. These two sequence...

Thyroglobulin is a high molecular weight glycoprotein which has previously been shown to contain approximately 300 monosaccharide residues per molecule in the form of galactose, mannose, glucosamine, sialic acid, and fucose (2). The aim of the present investigation was to initiate a study of the structure of the carbohydrate portion of this glycoprotein by determining the size, number, and comp...

Associations between positive thyroid autoantibodies and total blood mercury in women were evaluated using the National Health and Nutrition Examination Survey (NHANES), 2007-2008. Women are at increased risk for autoimmune disorders, mercury exposure has been associated with cellular autoimmunity and mercury accumulates in the thyroid gland. We used multiple logistic regression to evaluate the...

Tissue-specific gene expression depends on the interaction between tissue-specific and general transcription factors. DREAM is a Ca2+-dependent transcriptional repressor widely expressed in the brain where it participates in nociception through its control of prodynorphin gene expression. In the periphery, DREAM is highly expressed in the thyroid gland, the immune system, and the reproductive o...
