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 ...
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 ...
The prolactin receptor (PRLR) is a type I cytokine receptor [1] encoded in humans by the PRLR gene on chromosome 5p13-14. It is the receptor for prolactin (PRL). The PRLR can also bind to and be activated by growth hormone (GH) and human placental lactogen (hPL).
High levels of prolactin during pregnancy and breastfeeding also increase insulin resistance, increase growth factor levels (IGF-1) and modify lipid metabolism in preparation for breastfeeding. During lactation, prolactin is the main factor maintaining tight junctions of the ductal epithelium and regulating milk production through osmotic balance.
Thyrotropin-releasing hormone (TRH) is a hypophysiotropic hormone produced by neurons in the hypothalamus that stimulates the release of thyroid-stimulating hormone (TSH) and prolactin from the anterior pituitary. TRH has been used clinically for the treatment of spinocerebellar degeneration and disturbance of consciousness in humans. [1]
Testosterone, prolactin, thyroid and other hormone tests. These hormones can all affect your performance. You can check them with a simple blood test and often get your results within a few days.
Prolactin-releasing peptide (PrRP) is a peptide hormone that in humans is encoded by the PRLH gene. [5] PrRP stimulates prolactin (PRL) release and regulates the expression of prolactin through binding to the prolactin-releasing peptide receptor (GPR10).
In women, prolactin is the hormone that regulates milk production. High prolactin levels can lead to a bunch of issues like infertility, intimate problems and bone loss, as well as breast pain and ...
