Both TRH and somatostatin are also detectable by radioimmunoassay in thyrotrophs at embryonic day 14 (Harvey et al.
The anterior lobe consists of several different cell types (somatotrophs, mammotrophs, corticotrophs, thyrotrophs, and gonadotrophs), which are involved in the biosynthesis and secretion of key hormones (growth hormone, prolactin, adenocorticotropic hormone, thyroid-stimulating hormone, and follicle-stimulating hormone/ luteinizing hormone, respectively) that regulate multiple, diverse, and important physiologic and metabolic functions in the human body (2).
Investigations revealed hyperprolactinemia and ACTH deficiency with normal function of the rest of the pituitary hormone-producing cells including thyrotrophs.
In hypothalamic disease, there is a delayed and exaggerated response to TRH because the thyrotrophs take some time to "wake up" after a prolonged lack of stimulation by endogenous TRH.
