  2. Prolactin - Wikipedia

    en.wikipedia.org/wiki/Prolactin

    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 ...

  3. 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.

  4. Witch's milk - Wikipedia

    en.wikipedia.org/wiki/Witch's_milk

    The hormone prolactin has a key role in lactation and breast development in the human body and it is also a functional component of homeostasis. [15] It has varying originations including the central nervous system (CNS), the immune system, mammary glands, and uterus.

  5. Pregnancy hormones - Wikipedia

    en.wikipedia.org/wiki/Pregnancy_hormones

    During pregnancy, the production of prolactin by the mother increases steadily, starting at 6–8 weeks of gestation and continuing until the end of the pregnancy. [32] Prolactin levels in the human fetal circulation see a gradual increase from around 30 weeks of gestation until birth. [32]

  6. Lactation - Wikipedia

    en.wikipedia.org/wiki/Lactation

    During lactation, prolactin is the main factor maintaining tight junctions of the ductal epithelium and regulating milk production through osmotic balance. Human placental lactogen (HPL) – from the second month of pregnancy, the placenta releases large amounts of HPL. This hormone is closely associated with prolactin and appears to be ...

  7. Maternal physiological changes in pregnancy - Wikipedia

    en.wikipedia.org/wiki/Maternal_physiological...

    The mother's body adapts by increasing parathyroid hormone, leading to an increase in calcium uptake within the gut as well as increased calcium reabsorption by the kidneys. Maternal total serum calcium decreases due to maternal hypoalbuminemia , but the ionized calcium levels are maintained.

  8. Human milk immunity - Wikipedia

    en.wikipedia.org/wiki/Human_Milk_Immunity

    Bio-active components in human milk are speculated to colonize in human milk in several ways including secretion by the mammary gland, epithelium cells, and by milk cells. [3] [12] Maternal immune factors are transferred by lymphocytes traveling from the mother's gut to the mammary gland [8] where the secretory cells of the breast produce ...

  9. Hypothalamic–pituitary–prolactin axis - Wikipedia

    en.wikipedia.org/wiki/Hypothalamic–pituitary...

    Prolactin, a major hormone of the HPP axis.. The hypothalamic–pituitary–prolactin axis (HPP axis), also known as the hypothalamic–pituitary–mammary axis or hypothalamic–pituitary–breast axis, is a hypothalamic–pituitary axis which includes the secretion of prolactin (PRL; luteotropin) from the lactotrophs of the pituitary gland into the circulation and the subsequent action of ...
