Prolactin (PRL), also known as lactotropin and mammotropin, is a protein best known for its role in enabling mammals to produce milk. It is influential in over 300 separate processes in various vertebrates, including humans. [5] Prolactin is secreted from the pituitary gland in response to eating, mating, estrogen treatment, ovulation and ...
The most common complex found in blood consists of prolactin and immunoglobulin G (IgG). [1] While the free prolactin hormone is active, prolactin in the macroprolactin complex does not have any biological activity in the body and is considered benign. [2] However, macroprolactin is detected by all Laboratory tests that measure prolactin in ...
The magnitude that prolactin is elevated can be used as an indicator of the etiology of the hyperprolactinemia diagnosis. Prolactin levels over 250 ng/mL may suggest prolactinoma. Prolactin levels less than 100 ng/mL may suggest drug-induced hyperprolactinemia, macroprolactinemia, nonfunctioning pituitary adenomas, or systemic disorders.
Hypoprolactinemia can result from autoimmune disease, [2] hypopituitarism, [1] growth hormone deficiency, [2] hypothyroidism, [2] excessive dopamine action in the tuberoinfundibular pathway and/or the anterior pituitary, and ingestion of drugs that activate the D 2 receptor, such as direct D 2 receptor agonists like bromocriptine and pergolide, and indirect D 2 receptor activators like ...
A prolactin cell (also known as a lactotropic cell, epsilon acidophil, lactotrope, lactotroph, mammatroph, mammotroph) is a cell in the anterior pituitary which produces prolactin (a peptide hormone) in response to hormonal signals including dopamine (which is inhibitory), thyrotropin-releasing hormone and estrogen (especially during pregnancy), which are stimulatory.
Prolactin and insulin-like growth factor binding protein are two examples of the hormones and growth factors that relaxin can stimulate the secretion of. [21] Preprorelaxin is the collective term for the signal peptide , B chain, C peptide, and A chain found in the coding area of human relaxin genes. [ 22 ]
Elevated prolactin levels in the patient's serum are indicative of hyperprolactinemia, but are not specific to prolactinoma, meaning that other diseases causing similar symptoms could produce the same test results. Similarly, tests that use dopamine agonists to suppress prolactin production are not able to rule out other diagnoses. [2]
