  2. Prolactin - Wikipedia

    en.wikipedia.org/wiki/Prolactin

    The D 2 receptor is involved in the regulation of prolactin secretion, and agonists of the receptor such as bromocriptine and cabergoline decrease prolactin levels while antagonists of the receptor such as domperidone, metoclopramide, haloperidol, risperidone, and sulpiride increase prolactin levels. [82]

  3. Vasoactive intestinal peptide - Wikipedia

    en.wikipedia.org/wiki/Vasoactive_intestinal_peptide

    The production and release of the neuropeptide VIP is centralized in the hypothalamic and extrahypothalamic regions of the brain and from there it is able to modulate the release of prolactin secretion. [24] Once secreted from the pituitary gland, prolactin can increase many behaviors such as parental care and aggression.

  4. Dopaminergic pathways - Wikipedia

    en.wikipedia.org/wiki/Dopaminergic_pathways

    This pathway controls the secretion of certain hormones, including prolactin, from the pituitary gland. [9] "Infundibular" in the word "tuberoinfundibular" refers to the cup or infundibulum, out of which the pituitary gland develops. regulation of prolactin secretion [10] hyperprolactinaemia [10] Hypothalamospinal tract

  5. Hyperprolactinaemia - Wikipedia

    en.wikipedia.org/wiki/Hyperprolactinaemia

    Elevated prolactin blood levels are typically assessed in women with unexplained breast milk secretion (galactorrhea) or irregular menses or infertility, and in men with impaired sexual function and milk secretion. If high prolactin levels are present, all known conditions and medications which raises prolactin secretion must be assessed and ...

  6. Pregnancy hormones - Wikipedia

    en.wikipedia.org/wiki/Pregnancy_hormones

    Dopamine released by many groups of neurons in the brain inhibits the secretion of prolactin by activating D2 Dopamine receptors on lactotrophs in the pituitary gland. [31] Prolactin directly stimulates hypothalamic dopamine neurons, which in turn inhibit the secretion of prolactin, creating a succinct negative feedback mechanism for regulation ...

  7. Prolactin cell - Wikipedia

    en.wikipedia.org/wiki/Prolactin_cell

    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.

    How can you tell if they’re safe past their expiration dates? Here, doctors explain how long most vitamins last and any risks associated with taking expired vitamins.

  9. Arcuate nucleus (hypothalamus) - Wikipedia

    en.wikipedia.org/wiki/Arcuate_nucleus_(hypothalamus)

    Dopamine inhibits prolactin secretion, so when the TIDA neurons are inhibited, there is increased secretion of prolactin, which stimulates lactogenesis (milk production). Prolactin acts in a short-loop negative feedback manner to decrease its levels by stimulating the release of dopamine.
