Patterns of prolactin secretion
2020, Molecular and Cellular EndocrinologyCitation Excerpt :This rise is completely dependent on changes in ovarian steroid levels, including the abrupt decline in progesterone that precedes parturition together with rising estradiol, and is associated with a reduction in NEDA neuronal activity (Andrews et al., 2001). Remarkably, this reactivation of prolactin secretion occurs at a time when placental lactogen is still high, indicative of a change in the normal feedback system whereby elevated PL should activate NEDA neurons (Fliestra and Voogt, 1997; Grattan and Averill, 1995). Previous suggestions that the NEDA neurons become insensitive or unresponsive to prolactin (Arbogast and Voogt, 1996; Demarest et al., 1983) were not supported by direct measurement of neuronal activity (Romano et al., 2013).

2020, Handbook of Clinical NeurologyCitation Excerpt :The mechanisms mediating this adaptive response are only starting to be elucidated. Despite the presence of placental lactogen and rising levels of prolactin, the TIDA neurons apparently no longer release dopamine, rendering the short-loop negative feedback system functionally inactive (Ben-Jonathan et al., 1980; Demarest et al., 1983; Grattan and Averill, 1995; Fliestra and Voogt, 1997). The original perception that hypothalamic dopamine neurons show a “loss of response” to prolactin at this time has proved to be incorrect.
