Thyrotrophs are endocrine cells present in the anterior pituitary producing thyroid stimulating hormone (TSH) of molecular weight 28 kD. ?Thyroid stimulating hormone (TSH) is a glycoprotein that is made up of 201 amino acid residues and has two subunits i.e, alpha and beta subunits. The alpha subunit (MW 13kD) is immunologically similar to the alpha subunit of the other anterior pituitary hormones. The beta sub-unit is biological active component of TSH and it is unique to TSH and is structurally distinct. To identify thyrotrophs endocrine cells without any cross-reactivity with gonadotrophs, antibodies should be raised and directed to the TSH beta subunit must be employed. The thyrotrophs number remains constant throughout the life, the cells of Thyrotrophs do exhibit important variability in size and in frequency in certain disorders and with certain hormonal treatmentst.
