Novel chimeric thyroid-stimulating hormone-receptor bioassay for thyroid-stimulating immunoglobulins

Thyroid Stimulating Hormone Receptor

Thyroid stimulating hormone receptor (TSHR) plays a pivotal role in thyroid hormone metabolism. It is a major controller of thyroid cell function and growth. Mutations in TSHR may lead to several thyroid diseases, most commonly hyperthyroidism. Although its genetic and epigenetic alterations do not directly lead to carcinogenesis, it has a crucial role in tumor growth, which is initiated by sev...

Thyroid Stimulating Hormone Thyroid Stimulating Hormone

Thyroid-stimulating hormone and thyroid-stimulating hormone receptor structure-function relationships.

This review focuses on recent advances in the structure-function relationships of thyroid-stimulating hormone (TSH) and its receptor. TSH is a member of the glycoprotein hormone family constituting a subset of the cystine-knot growth factor superfamily. TSH is produced by the pituitary thyrotrophs and released to the circulation in a pulsatile manner. It stimulates thyroid functions using speci...

Thyroid-stimulating immunoglobulins in neonatal Graves's disease.

Two patients with neonatal Graves's disease are reported. One of them had a delayed onset because of suppression of the fetal thyroid gland by antithyroid drug taken by the mother during pregnancy. Thyroid-stimulating immunoglobulins (TSAb), measured by a receptor assay, were present in both babies when they were thyrotoxic, and also in their mothers. TSAb were undetectable in both babies 1 yea...

THYROID FUNCTION TESTS Thyroid Stimulating Hormone (TSH): The thyroid stimulating hormone (TSH) assay measures the concentration of thyroid stimulating hormone in the serum. TSH assays

The thyroid stimulating hormone (TSH) assay measures the concentration of thyroid stimulating hormone in the serum. TSH assays have been classified by "generation" based on the functional sensitivity of the assay, i.e., the lowest concentration at which the assay is able to maintain an inter-assay precision, expressed in terms of percent coefficient of variation (%CV), of 20% or less. Virtually...
